Je pense que les applications serverlesses, les fonctions serverlesses,
sont les places où nous, à Fermion, on construit des outils comme Spinn,
peuvent vraiment faire des improvements vastes et dire que,
ici est le premier step pour pourquoi l'assemblée web est cette troisième wave de computing cloud.

Hello, welcome to the DevTools FM Podcast.
This is a podcast about developer tools and the people will make them.
I'm Andrew and this my cohost Justin.
Hey everyone, our guest today is Matt Bütüncher.
If you work with Kubernetes, there's a really good chance you've used one of Matt's tools.
Welcome, Matt! So glad to have you on.
Et avant de commencer,
vous voulez dire à nos listeners un peu plus de vous-même ?
D'abord, je me sens comme un nom de la compagnie pour tous les tools de Kubernetes.
Je pense que le meilleur moyen de me décrire moi-même est de être un philosophiste en récoverie.
Mon objectif original était d'être un philosophiste, comme professeur de philosophie.
Je suis un étudiant de philosophie.
Je l'ai fait pour un moment.
Mais quelque part, along la ligne,
il me semble qu'il faut payer votre chemin à l'école.
Et les choses comme ça.
Et la philosophie ne pourrait pas être le plus cher à faire.
C'est probablement de plus en plus.
Le top 98%.
Non, c'est pas ça.
J'ai commencé à écrire des codes.
J'ai sorti dans la classe de la classe,
j'ai carried ça en college,
j'ai travaillé dans la classe de la compétition.
Je étudie la philosophie.
Et à un moment,
j'étais comme,
« Man, la philosophie s'éteint vraiment lentement.
La science de la compétition s'éteint vraiment vite.
Et je l'aime beaucoup plus.
»
Je me suis donné la première partie de mon travail
dans des systèmes d'engénagement,
et des systèmes de la compétition de la compétition.
J'ai fait du Drupal pour longtemps.
Drupal m'a fait un travail en cloud.
J'ai travaillé en cloud,
originalement dans les sites d'un drupal,
et j'ai fait des tours de la compétition
et dans l'opinion d'un stack d'opinion.
J'ai vraiment fallu m'amuser avec le cloud.
J'ai fait ça pour les dernières années.
Et puis,
en passant près de la présence,
plusieurs années auparavant,
j'ai eu un petit start-up,
un company en Boulder,
qui s'appelle DEIS.
Nous étions construitre les solutions de Kubernetes.
Nous avons commencé le projet de maison
et le guide des enfants illustrés de Kubernetes.
Encore une fois, Microsoft s'est dit
« Hey, y'a-t-il un grand groupe de gens
qui sont venus nous,
notre équipe de Kubernetes,
et j'ai spenté 5 ans à Microsoft.
J'ai vraiment, vraiment apprécié.
Mais, along the way,
quelque chose d'autre a été venu,
ce projet de WebAssembly,
j'ai dit « Oh, je dois faire ça. »
Donc, un bunch de gens m'a fait Microsoft
et ont commencé le start-up.
J'ai fait ça depuis novembre 2021.
C'est probablement le plus rapide que j'ai jamais
dit de ma histoire de vie.
Et c'est vraiment un peu dépressif
quand vous le dites.
C'est bon, c'est incroyable.
Il y a beaucoup de points.
C'est super intéressant.
J'aime toujours entendre des gens qui ne sont pas
au point d'enfinir les sciences de computer,
et puis, ils sont venus pour tout le monde.
C'est génial que vous êtes
en train de être un PhD.
Et vous vous dites « Ah, non, je ne vais pas. »
Je l'ai fait dans la partie où j'avais
de payer pour tout ça.
Et puis, c'était quand je l'ai décidé
que je ne voulais pas faire.
Donc, Kubernetes,
si nous parlons de Kubernetes
en contexte de ce que nous essayons de solider,
on a
cette première wave de computing cloud
qui vient de l'alimentation,
des machines virtuelles.
Et tout de suite, on est allés
collectivement dans ce moment
de dire « Oh, c'est correct.
Je peux prendre mon système de opérance
et je peux le packager et
le laisser à l'autre part.
Et ils vont faire la partie que j'aime
faire, et je vais juste continuer
de chier ma image de système de opérance
à chaque fois.
Et on est tous en love
avec cette idée parce que ça signifie
que nous ne sommes pas les slaves de la blanquerie
dans le centre de la data.
Et puis, nous commençons à falloir
de l'amour avec la chose que nous avons
déjà passionnée.
Pour moi, c'était comme « Je ne peux pas
ne croire, je n'ai juste pas pris 3 heures
de construire cette image, de pushing ça
dans la registre. Et maintenant, je
réalise que j'ai oublié de
inclure Curl. Donc, je vais devoir faire
l'entire tout de suite.
Et, en même temps,
nous nous en dealons avec l'orchestration
de la
« Developer Tool » ou « DevOps Tooling »
comme « Chef & Puppet ».
Et, en même temps, nous nous sommes
en même manière. « Hey, c'est génial, je peux
faire la code de procédure et, en fait,
en évaluant un tout petit peu de commandes, je peux
juste en chier tout de suite
dans
Ruby ou Python, et
tout de suite,
c'est comme l'artifact que j'ai appris.
Et puis, along comes
this next shift, right? And containers
become a thing, and we start to fall in love
with the lighter, you know, the little spelt
container that feels so much smaller
than the gigantic virtual machine
image I was building.
And this, you know, Kubernetes
comes along and the orchestration model
looks so much more attractive, and suddenly we're talking
about declarative. And declarative is the
best thing ever because procedural is so
yesterday. I used to have to write this
ugly old Ruby code in order to describe
what my architecture looks like, and now
all I do is write this beautiful YAML.
And, you know, we kind of go through these funny
phases, and
again, every time, to me, it's like
I found the last tool I'll ever need.
This is the best thing I've ever found, you know,
this will solve all of the world's
problem. Let me tell you why Kubernetes
is going to make you a happier person.
And then a few years later,
like now, I'm like, if I never see a YAML
file again, I will be happy.
You know, declarative, ah, so much of a pain
to use declarative infrastructure,
and, you know, the wheel
moves on, I guess.
Indeed, indeed. The cycle continues.

Yeah, so earlier you mentioned
that you've worked on a bunch of different
Kubernetes pieces of
tooling. So, like, what are those, and like, what
do they help you do?
Kind of the big one.
So, does it give a little bit of context?
You know, I talk about, you know, moving
from the virtual machine world into the
container world, started
working at DEIS.
DEIS was building a platform as a service.
We wanted to build the open
source competitor to Heroku.
And we wanted to do it using containers,
which were, of course, the newest
shiniest thing in view at the
moment. And it was going great, and
we were really excited about what we were building.
We were using build packs, just like Heroku.
And then Kubernetes landed,
was made public.
And we looked at it,
and I had come from Google
prior to that one, so there was a sense in which
looking at it was like, oh, hello
border gold friend, right? And in a sense
it was also like, oh, you know, I understand
right away why this would be a really
powerful way to orchestrate our stuff
in our platform as a service
thing, right? This is going to be
what sets us apart from Heroku. We'll have
containers, we'll orchestrate them, we
won't have sort of the startup time problems
that Heroku at that time was having.
And then we got working
on Kubernetes and realized
that it was actually kind of hard
to install things into
Kubernetes.
You know, you ended up having to write a YAML
file for each different artifact
you wanted to describe. So if it's a service
gateway, you're writing a service, if it's
a piece of secret
data, you're writing a secret YAML file, you need
replica sets
or at the time replication controllers
and then later on deployments and all this.
And we're writing a lot of YAML.
And we were, and I was writing the same
YAML-y objects over and over
again to try and install the latest
version of our platform into Kubernetes.
And we had Hackathon, a company
Hackathon as part of sort of an all hands
meeting. And so I came into that
frustrated with
not wanting to write the same YAML
anymore. And
got together with a couple of other people
at DEAS who were also similarly, one of
them was looking at Kubernetes and the other one was
was kind of working on
something vaguely npm-ish
at the time. And we're kind of chatting
together and going, you know
we could build a package manager for Kubernetes.
So we built this package manager
called Catesplace. This was our
entry for our Hackathon project
where the prize was a
$75 Amazon gift card.
And we're like, we are
going to win that gift card. Nothing is
going to stop us. You know, we go out for the team
dinner and you know, we're like, all right,
well, we finished the main course. Do you think we can kind of
sneak out and go work on our package manager?
So we wrote this package manager called Catesplace.
It was sort of approximately
modeled on, you know, a little, you know
one teaspoon of npm, a couple
tablespoons of apt-get
and we got to the
show and tell thing and we got there
and demoed Catesplace.
And everybody was like, yeah, that's neat. And we did end up
winning the $75 gift card. We split
it three ways. I blew mine on coffee
and I am not ashamed to admit that.
So the
day after that
the CEO
and so the offsite's all done and
the dust has settled and the CEO
and CTO call me
and I'm like, uh oh, when the CEO
and CTO call you at the same time, you're in trouble
for something and I'm thinking, did I do
anything at the also?
And they're going, so you know that
thing, that demo you did, the little
package manager thing? I'm like, yeah, yeah, yeah.
And they're like,
we think there's some potential for
that. I'm like, oh, good, good. And they're like,
we think you should start working on that.
Stop working on the paths so much
and really kind of pivot over and work on that
thing. And I said, oh, good, good. And they said
there's just one thing. We really
don't like the Catesplace name.
It sounds like a coffee shop
and I'm like, I know, right? Doesn't it sound
pleasant? It's not like the coffee shop. They're like, no,
no. So I called Jack Francis,
one of the other two guys that I was working on
along with Remis, called Jack Francis
and I'm like, I got
good news and bad news. The good news is, we can work
on this Catesplace thing, you know, forever.
And the bad news is, we have to come up with a
new name and they kind of want it to be, you know,
Kubernetes-ish. So we sat around
with a nautical dictionary, just on the
phone together, reading each other
entries out of a nautical dictionary back
and forth. It's like, Mast, Nope.
Captain. Well, that's actually what
Kubernetes means. We're just kind of back and forth
in Jack's version
of the story, we said the same word at the same time
but really Jack said it and I probably just
repeated it back. He's like, what about Helm?
I'm like, oh, yeah.
So, we renamed
the package manager Helm, started working on
that and the project kind of grew
by leaps and bounds, well beyond
what we thought it would
ever become.
I think at this point it's probably
70-ish percent of Kubernetes users use
Helm to install
Helm charts, also from the nautical
dictionary, which were really, you know, a great
way to solve that problem that I had at the beginning.
You can encapsulate your YAML files, you can
templatize them, then you don't have to write
nearly as much YAML in order to use Kubernetes
and hopefully the world is a slightly better place.
There's two lessons here.
Good things come from hackathons.
Yup. And pick a theme,
it'll make things easier to name.
Worked for Ruby
and that whole ecosystem, right?
Yeah. Back when I worked at Artsy,
it was physics and art terms.
So, we had like a list of physics
things, so we had like metaphysics
as our GraphQL service and force
with the HCP
service and yeah.
Oh, but I mean, I gotta say
the Java ecosystem as it got going,
the number of bad coffee metaphors,
we might have actually passed
some kind of threshold after which every
new project, it was like, oh,
I don't think Frappuccino should be the name
of the thing.
Yeah. I think CoffeeScript killed all of that.
We overcaffeinated at that point.
I guess we had Java, then JavaScript, then coffee.
Yeah, we really leaned hard
into the caffeinated beverage thing for a while.
I think the trick for the philosophy
behind naming things is that
the names have to be differentiable
in some meaningful way.
So, if you can tie loose logical
and make a loose logical analogy
to these two things, but when it's just
a bunch of like
nouns for drinks or whatever, it's
much harder to say, yeah,
this drink kind of represents this
web service, you know?
Yeah, I mean, it gets to be a stretch really at some point.
We used to have an inside
joke at Deus that we would substitute
out the word coffee with the word slurm
and it was like one of those things where
the sort of
onomatopoetic
sound behind slurm
just sound so gross that
you know,
kind of makes you shiver a little bit.
I don't know, it was slurm from futureama,
I think it might have been from futureama.
I thought it entirely share of the origin, that was.
So, I want us to transition
to talk about spin a little bit, but before we do that,
so, Kubernetes
is like, infamous
for both being like incredible, incredibly
helpful, but also
pretty hard to wrap your head around
and like all of its facets and really get
into the weeds. Something that I
love is that you helped co-author
like Illustrated Children's Guide
to Kubernetes and I'm like super
curious, like how did that come about? Like who's like
you know what, we need to make a children's
book out of this, that'll help.
I mean, it's often the solution to life's problems.
I am not
kidding you when I say this,
the Illustrated Children's Guide to Kubernetes
happened the same day that Helmed it.
So,
In this whole
offsite that we were having
where we had the hackathon
we, the CTO
and I and a few others had been
evaluating Kubernetes as the platform to pivot to
and yet there was still a huge contingency
at the company that had never heard of
Kubernetes and of course
I mean even the word itself is so clumsy
that in order to get people kind of engaged
in this, it's a difficulty, right?
So, Gabe, who's the CTO
comes up to me and says, yeah, I'd really
like you to introduce Kubernetes to everyone
during the offsite and I said, okay, like
all of engineering and he says, oh no, no
when I say everyone, I mean like marketing
is gonna be in the room, finance is gonna
be there, I mean just kind of introduce it to
everybody and I said
oh, okay
and I said, but don't worry
I got you covered, I'm gonna give you
the slot right after lunch and I'm like
the slot when everybody's falling asleep
right after they had a really big meal
that'll be great, Gabe, that'll be great
so the night before
I had to give this presentation
I'm just kind of like
trying to build some kind of presentation
to articulate
even what Kubernetes was
let alone the value of Kubernetes
in this kind of generic way
and you know, I have three daughters
and I don't know what the
what the moment was but I'm like
it would be really funny if I took a couple
of the kids stuffed animals
and took pictures of them
and made up a story about a little
PHP program called Fippy the Giraffe
who was trying to get deployed on
Kubernetes and so
I took a couple of pictures, I wrote a this
really, really bad PowerPoint
presentation but it was essentially
the text of the Illustrated Children's Guide of Kubernetes
and during
lunch I grabbed a big old poofy chair
from another room in the hotel where we
were doing the conference, dragged it across the lobby
into the room and put it up in the front
and sat in the front like I was reading a story
and projected this slideshow behind me
and gave the first version of the Illustrated Children's Guide
of Kubernetes to Kubernetes
now marketing was in the front
yeah, yeah, so marketing is in the room
watching this presentation
and Karen too
is watching the presentation
kind of nodding along
and I didn't know if I'd kind of reached
I don't know, I had no idea
whether I had done a good job, it was a really
rinky-dink presentation, there really was nothing
special about this. Couple of weeks later
Karen calls me and says, hey, you know that
that slide deck you showed
at the off-site, I have this
wild idea
what if we really made a kid's
book out of it? And what if we
you know, use this as marketing material
we could give it away at KubeCon
which the very first KubeCon was coming up only a couple
of months away, you know this would be a great way
to get people enthusiastic about
Kubernetes, we could mail it to people
and she's like
I've already lined up an artist, I'm working on
some storyboards, thankfully she's
much better at all of these things than I am
because otherwise
you'd be looking at this kind of funny looking
giraffe and Karen's actually
Karen is brilliant
before asking the illustrator
to design the giraffe, we're dais, we're on a
shoestring budget
we can't afford a lot of stuff but she really
wanted to have a giveaway to go along with the book
so she goes and finds all the places
that can source little squishy toys
in the shape of you know, giraffes
and owls and the characters in the book
and finds some
that look you know
appropriately squishy and kind of cartoonish
and then sends our illustrator
those and says
can you just kind of riff on these
so that they'd be close enough to your illustrations
that we could give these out
and so we kind of launched the book
as a little bootstrap start up with
you know, an illustrated
you know, illustrated book along with
you know, a line of toys
to go with it and we gave those away
at the first KubeCon and it just kind of took off
from there, I think at this point there were several books
when Microsoft acquired
dais
CNCF reached out and said you know
would you be willing to donate
Fippy and that whole kind of illustrated
children's guide to CNCF so that we could use it
as more like a mascot
and
Karen et I were very enthusiastic about that
and Microsoft
actually was very enthusiastic about that too
because they had you know
really started investing in CNCF in the Kubernetes space
and so
gradually we got to kind of turn things over
to CNCF which in and of itself
was really exciting and now there are all these other
you know, illustrated children's guide
books, you know, illustrated by
different people, written by different people
and it's always fun to kind of see this and go
yep, that
silly little after lunch
presentation, it just took the right person
in the audience to see that and go
we could really do a lot with that
this has been kind of a wild ride
and it's like, okay, so I'm proud of the code
for Helm, right, and I feel like
I should
view the illustrated children's guide as a thing to be
just a little bit embarrassed about but I'm not, I think I
actually am more proud of the illustrated
children's guide at this point than any piece
of code I've ever written in my life
where you can look back on the children's
book and go, oh, that was fun, you can look back
on your old code and go, oh, god, what was I doing?
Yeah, you are
not wrong, I mean, that is totally
why that's the case, it's like the stuffed animals
are still cuddly, the code
yeah, it's just quickly all the way
at this point, it's like oh, oh my goodness
I wonder why we
why we have that feeling about our code
I mean, every engineer I've ever talked to is like
I get embarrassed about the code I wrote back then
do we really learn
so fast that the code from only
six months or a year goes that embarrassing, it really
seems to be the case in which case, you know
that says something about human
beings and our ability to improve
or at least human beings and our ability to cast
shade on things we've already done
I think it's in part
maybe that our taste
over time changes, not that
something is objectively good or bad because you
you're generally, as you look
at code from another person, you might
say, oh, this isn't how I would write it
but like it's not my code so it doesn't matter
yeah, but when you look back on your old code
you're like, I have this taste now
and I wrote it that way and I would never
write it that way now and like why did I do
that? I don't think we
acknowledge how judgmental we are
about ourselves
past me was such an idiot but present me
I'm great
speaking of present you
let's stop talking about what you have
done, let's talk about what you are doing so
the newest open source project
you've been heading and which is the like
underlying
tool for fermion
is spin, so what is spin and what
prompted you and your team to build it
so spin is a developer tool
for building serverless
applications using web assembly
and I'll just kind of unpack all of that but
really with the story of why we decided this was
even remotely a good idea
to try and do this kind of thing
I mean web assembly, so let's start with web assembly
just as a technology
we've had the browser for quite a while
now, one language has
done a really has this really kind of a
master, you might have noticed there was a language
that amassed kind of a following in the browser world
and kind of broke out from there, javascript
something like that I can't remember the name of it
you know, but others have failed
right java applets which were really
kind of the first other language to be embedded
inside of the browser came and went
vb script had a brief stint in the browser
silverlight you know flash
flash, we tried all of these different techniques
for extending
the way that we wrote software inside
the browser and it seemingly time and again
we
these technologies
failed, right, for one reason or another
each of these technologies failed yet
we still like the idea of actually being able
to run something else inside of the browser
on
in must have been around 2015
the team at mozilla
kind of introduced
their version of what would be
a really interesting way of
extending the browser to run
something other than javascript
and rather than try and tackle
the sort of soup to nut story that applets
and silverlight and all of these did where it was really all about
building code and then you know owning
a piece of the UI and
and being able to paint widgetry of your
preferred kind of there web assembly
really started more modestly
web assembly really
started more modestly by saying
you know let's just figure
the developers said let's just figure out a way
to
execute different languages in the browser
which means really we need to build sort of a language
style virtual machine of the sort that you get
in Java or dot net
but whatever the characteristics
of this runtime are
it needs to be able
to do a couple of things really well
and the first one is going to be it's got to be able to interact
with javascript it's got to be able to interact
with its environment so that we can call
in and out of these binaries from javascript
the second one
was that it had to have a really excellent security
sandbox model because as we all know
from using the internet
it is not entirely a safe place
and people try and do dastardly things
with your computer
and so they really wanted an even stronger
security sandbox model than what you get
in javascript and then they wanted kind of a binary format
that was going to be lightweight and easy to move
around fast to load fast to start
execution because we are
very very attention
deprived people who wait about 100 milliseconds
before we start getting grouchy
that we are looking at a white screen
and so these kind of characteristics
were the driving force behind
the original web assembly specification
now Mozilla did a couple of things that were really smart
here first one is in my opinion
they didn't try and tackle the UI layer
too right they just said look we'll make it interact
with javascript javascript can do
all the DOM goodness and we won't have to
invent another you know abstract
windowing toolkit like java had
or the whole kind of flashing
the second one was that they decided
that this road was best
best
traversed with friends and so they
enlisted the chrome team
the safari team the
IE team at the time
and got everybody sort of in on the
idea that they would standardize it under
W3 just like html and css
and then everybody could
collectively work in lockstep
to introduce support into the browser
so that was web assembly
so let's just put web assembly on a
shelf for a moment and go back to
Kubernetes
that's where we all want to talk more about
more yaml so we're working
in Microsoft now after deus
has been acquired working inside
of the container team in azure
and I had what I swear is the best job
at Microsoft my job
was to build open source software that exhibited
how containers and Kubernetes were going to
solve your problems and so along
with helm we just kind of kept dropping
one after another a bunch of interesting
what we thought were interesting open source projects
things like brigade that were really more like
etl pipeline kind of thing
and CNAB which is a way to package stuff
and we would contribute these up to linux foundation
or cncf whatever
whatever sort of made sense
and the way we got inspired
was to go out there and talk to people and say
you know what do you wish you could do with containers
you know at kubekons
go out to customers of Microsoft
or chat with other teams inside of Microsoft
when you ask questions like that
you're going to get some good ideas
but sometimes you're not going to get good ideas
you're just going to have problems you can't figure out
how to solve and we started to amass
a number of those problems
one of them
was that we really wanted to figure out
a way to sort of instantly scale up
and down so when you think about kubernetes
right I deploy my little application
into kubernetes
and in order to make sure
that this application is always going to be available
I want to have
3 or 5 or 7 or 9 replicas
running somewhere in my kubernetes cluster
so that if a note or 2 or 7 die
I still have a version of my application
or so that if suddenly
we trend on hacker news and we get
tens of thousands of requests coming in all at once
I don't have to
start denying service to some of them
things are just pre-scaled so that I can handle the load
and this solves really kind of two big problems
the outage problem
and the scalability problem
but it's wasteful
and
that's a problem for
me as a consumer because it means I'm paying
for 3 or 5 or 7 or 9 instances
of my app running instead of paying for
one instance of my app running
or at 2 in the morning when nobody's visiting
my app I'm still paying for 3 or 5
or 7 or 9 of these things even when nobody
is looking at or using my app
but so what we wanted to be able to do
was figure out a way where we could scale down
ideally to zero
when the app is not being used
nothing's running when traffic starts
to come in I start up an instance
if a node dies I start up another instance somewhere else
but I'm not running all of these things all of the time
so we tried various ways to do this
with containers and with virtual machines
and we were just kind of drawn a blank
we just couldn't find
a way to make containers
start fast enough
that they could do the work we wanted them to do
without making a sacrifice
that in order to start a container that fast
there was nothing worth having inside of the container
so really we were looking at
seconds to start a container
when as we talked about a couple minutes ago
your users got an attention span of 100 milliseconds
so they're not going to wait for 5 seconds
or 12 seconds or whatever for your container
to start up when they come in and you're in the scale up motion
so that was kind of the first catalyst
and there were several others we were frustrated by the fact
that docker containers were not cross architecture
and cross platform and especially
as ARM processors got more popular in the data center
we're like
here we are at Microsoft telling people
ok well if you want windows container support
and linux container support and intel
support and ARM support
then here's what you do you build yourself a matrix
you're compiling and building these things
oh and you're going to need different docker files
because ARM libraries are slightly different
than Intel libraries on linux
and windows obviously different
and this was a really frustrating story
to try and tell
it was obviously frustrating to everybody
when you think about it
in the contemporary platform engineering world
platform engineers are going well
if only we had an ARM version of this
we could run it a lot cheaper
well that means we have to throw it back over the wall
to the developers who are like are you kidding me
now I have to build a container on an architecture
I don't even have anywhere
and you're just introducing friction
all along both the development pipeline
and the social pipeline inside of an organization
so we're looking at problems like that
scale to zero
cross-platform, cross architecture
performance, some of these kinds of things
and just making no headway
in the container ecosystem
what was the time frame on this
oh this was 2018
was when we were really kind of working hard
on these problems
and we all got together for we worked as a distributed team
that we were dais labs
when we were at microsoft
it was about half of the dais engineers became dais labs
and then we just kind of kept pulling in
people that we like to work with
and growing the team that way
so in 2018
we were up in vancouver
up on vancouver island in fact
for an off-site meeting
and we had finished a day of planning
and we had finished dinner and we were just kind of sitting around
chilling after this venting about
the many issues we were going to have to solve in helm
things like that
and somehow the conversation
sort of turned to these problems
that were feeling intractable
and we're in you know
you get that moment where you click into kind of the creative mode
and you're not thinking about
problem solving in the sense of applying
existing patterns
but you start going well what if
you know just throwing out an idea here
what if there were some other cloud
runtime in addition to
virtual machines and containers that we could draw from
what would that runtime have to look like
well it would have to have a really good security model
cause that's just table stakes for the cloud
isolation is what makes compute
the kind of thing it is
it also have to be really high performance cause we know
we need to be able to start things up in under 100 milliseconds
it also have to
you know be able to load really quickly
it have to be cross-platform, cross-architecture
and you know this is how we'd want to be able to use it
and we're kind of talking through that
and then started going you know
we should look into this, maybe there's some technology out
maybe we don't have to invent this
maybe there's a technology out there that'll
accomplish this for us
we had research Friday time
which was basically each person
could kind of do their own research on Friday
but several of us started looking
into technologies web assembly
being really one of the first ones that we looked at
and we're going well do any of these
fit that bill you know high performance
cross-platform scalability
and over and over
you know we tried all these WAC experiments with web assembly
and each time it seemed to be working out
and we did some things
that were false starts and went
ok well that's not the right way to use this technology
but we really realized that we could kind of pluck
web assembly out of the browser
drop it into a cloud environment
and all those virtues that web assembly had in the browser
the strong security sandbox
the easy ability to call in and out of the binary
the compact binary
format that was portable across
architectures and operating systems
those were exactly the things
that we needed to make a cloud runtime work for us
so and we discovered that there were
indeed some engineers at Mozilla
some engineers at Fastly who were all working on
kind of similar stuff and we
pooled resources together
they were building a runtime called Walsham time
that was a great
standards complaint really kind of cutting edge
staying along with the standards as they emerged
and it was a great web assembly
runtime for us to start with and we began
kind of building experiments
at this point we started going alright
you know we're
well out of our Microsoft
mandate of building cool container
technologies for Kubernetes
and we decided it was
time to kind of pack up
try the startup thing and ten of us
on the same day left Microsoft started
Fermion and said ok we've got
the kernel of an idea web assembly
can be the technology
for this kind of next wave of cloud
computing that'll sit adjacent to containers and virtual machines
and we started fresh and said alright
how do we envision this working
and we started building
the first thing we decided to do was
as one does say alright
we want to start by proving
that we can build something production grade
in Kubernetes
in web assembly that trauma is going to live with me
for a long time build something
in web assembly that we can run in production
on the server and really start to exhibit this
so we built kind of with toothpicks
and marshmallows kind of built our first
version of the runtime
and then we built because
this is what we do we built a content management system
in Rust
that compiled the web assembly that could run in
our little first version of this
runtime and it worked and in
February of 2022
we launched fermion.com
running in a web assembly
based CMS on the cloud
we use nomad instead of Kubernetes
nomad is an orchestrator from
from HashiCorp that we just really like
it's a process based orchestrator it's really great to use
and then that first kind of
toothpicks and marshmallow runtime
became spin a couple of months later
and spin was our attempt to say
okay we can build a generic developer tool
that will make it easy
for the developer
our core user story all of 2022
our core user story was
as a developer
I should be able to go from a blinking cursor
to a deployed application
into a deployed serverless
web assembly application in two minutes
or less right we just wanted to build a tool
that would make it so easy
for people to try out writing these kind
of web assembly on the server side
applications that at best they had
to invest you know a few minutes of their time
I mean realistically when you're getting started
everything's a little bit harder and it probably does take
around a half hour but it was like
actually you can get the hello world
running by downloading spin starting
everything up and you can actually have it running
in two minutes or less
and
that for us was just a really important
thing to do spin is open source
and we and so we started
layering on additional things microsoft
the same people that we kind of
you know left behind
then came back and said oh we'll help with this
and we started getting more external
contributors the github star account
started going up and we're like whoa what's going on here
right we didn't think anybody would even notice
us yet and then
you know over the last
well it's been just about a year now
we've seen spin really
take off and grow very rapidly
and
we've added from I think our first languages
we supported were just rust
and go if I remember
correctly and we figured out a way
to sort of do first class support
for you know kind of top shelf
support with SDKs and everything for rust
go go type script
javascript now python
we're working on java dot net the dot net
team really did most of the heavy lifting
for dot net support and then we're just kind
of working our way through red monks top 20
languages and moving as many over but
we also figured by using
something that's basically CGI
made new again CGI
for those of you who are much younger than I
am was it was
was the world's first attempted building
you know dynamic website
back ends right the way I wrote it was
a pearl script and the web server
you know would get a request and it would shell out
to a pearl script and execute that
pearl script it was definitely as safe
as it sounds and then whatever the pearl
scripts bit back out it would pipe right back
to the web browser and we were looking
at WebAssembly going actually if we just
support that very basic model then
then most of the WebAssembly languages
any of them that supported the standard
called the WebAssembly system interface
most of those languages would be instantly
supportable inside of spin so from
that we kind of instantly got
support for for Swift
and for
now like prologue
and all you know sort of
exotic languages like that new languages
like grain that's a WebAssembly specific
language and so it's been
exciting to kind of see that we can give
you know a decent
experience for a really broad swath
of languages and then kind of a top shelf
experience for the languages where we have
the where we know there enough developers that we can
build a good SDK and and give them
you know start building in things like database support
and key value storage support and things
like that so it's been it's been a really
fun year as we've kind
of seen this little project go from
the from from from a glint in the
eye to something that people are using
and finding enjoyment in
yeah that's
that's a both awesome context
and really interesting story so
my understanding I
haven't really kept as up to
date on wasm as I probably should
the sort of
first iterations of that didn't have a good
story realm like garbage collection like garbage
collected languages so you really had to use
like you know compiled languages that are garbage
collector doing man manual memory management
is that solved within wasm
or do you have to like sort of like build
a garbage collector for the languages that need
it and sort of like layer that in
yeah this is my understanding of that
incorrect I need I need like
the verbal equivalent of an asterisk
oh it's
solved asterisk
so
this this has been one of the
fascinating issues of trying
to write a general purpose
language
runtime right where anything from
rust to python
to be after java script should be able to
execute inside of this thing is that
languages aren't really
built typically
with the intent
that they will fit a generic model
right it's going back to the beginning of the conversation
right we're talking about how
languages are really like a reflection
of the way we think about the world and that's true
when we're talking about you know
using a functional programming language versus
object oriented one but the people the very people
who design these languages are designing
a new language because they want to express
a different way the way they think
is the best way of describing
these kinds of abstract systems and so
of course memory management
in rust which is
I know you had Steve Klamnik on a while
back right the rust memory manager
is amazing and very
very very different from
the java memory manager which
is different in turn from the way javascript
does memory management in python
and so the early
the first version of the web assembly specification
just didn't deal with it right said what every
host language runtime will need to provide its own
collection of memory management
and of course rust
does this very elegantly
and was one of the first languages that could easily
be implemented this way this sort
of yolo style of C was made
it such that C was fairly easy to support
but then you start to hit more complicated languages
more complicated compiled ones
like go
and and you know
if you use tiny go which is a great
it was a project originally built
for embedded go
but they really have embraced the kind
of web assembly ecosystem but they actually allow
you to choose different memory management
techniques including shut off memory
management altogether and you can compile
all these into the web assembly runtime and have a good time
scripting languages are a whole different
ball wax though and so you get really
kind of and so are the java languages right so you
really have three classes of languages so is it compile
all the way down to a binary format
and have a kind of slim runtime
those where the runtime is the scripting interpreter
and then you just feed it in the script files
and it executes and those that are kind of the hybrid
bytecody ones like java
or like the anything that runs in the
clrn.net and each of those
kind of brings its unique challenges when you're trying
to do the one size fits all on
to the web assembly runtime so
along the way
a lot of the web assembly standards
contributors began
working on a
standard memory management extension
to web assembly
that would make it so that make it
just a little bit easier so that instead of each language
having to implement their memory management inside
of web assembly the runtime itself could do the memory
management and language could hook in
that specification is not finished nor
is it really entirely broadly supported yet
but it already seems
to be picking up traction
I know the Kotlin team in particular
wants to do a Kotlin directly to web assembly
compile run and they've been
they've really been pushing the new
memory management spec
but still like within the last few months
python, ruby
java.net
all of those have had web assembly
implementations none of which use
the garbage collector specification
each of which which again is not
widely implemented each of which kind of
brings its own memory manager
and as it's
turning out you know
we're all kind of waiting to see
which technique actually
turns out to be more efficient
because when you use a generic
memory manager then there's some amount
of contorting your language to fit the
the abstraction that that provides you and
maybe that'll be hyper
efficient or maybe it'll be clumsy we're
not entirely sure we haven't seen a whole lot
of languages supported yet on the flip side
you know if you're just compiling your
runtime into web assembly and you've
already got your memory management
strategy in the runtime
then you know I don't to my knowledge
the python neither the python nor the ruby teams
did any major alteration
of their memory management
in order to compile the runtime into
web assembly so we'll kind of see
and I think that's
that's sort of the
the microcosm of the bigger story
with web assembly in that
you know we've got a generic runtime
that seems to be really well designed
and reasonably flexible
we're just now starting to see
the momentum build to the point where
some of us are going
are kind of you know sitting there with fingers cross going
I hope all these design assumptions
prove true because
I got a lot invested in this now
and you know so far it's been
it's been I wouldn't say smooth sailing
it's been good sailing right challenges
come up they get solved
rough drafts get replaced
by second drafts get replaced
by production quality code
and things keep looking better and better
it's an exciting time and maybe this is
why we get myopic
about how how enthusiastic we are
about today's technology while less
enthusiastic about yesterday's technology
it's exciting to watch this stuff sort of
unfurl in front of your eyes right and
to know that the thing that you
you banged your head against the keyboard
when you ran into it a month ago
is now
totally well supported and easy to do
and trivial and how come
wasn't this easy all the time
and then the things I'm banging my head
against the keyboard today I'm like I really
have to wait another month or two
we're so impatient
but it's been fun it's a lot of fun
to watch this ecosystem develop
develop rapidly
one of the cool things I think about WebAssembly
as a general technology observation
right we see technologies that are invented
for a niche and then they
and they stay in the niche for their entire life cycle
we see some that are generic languages
that then later find their niche I think Ruby is a good example of that
that was invented to be sort of like a system scripting language
and I think it must have been 5-10 years old
before Rails came along and suddenly
Ruby had a reason for existence
and then everybody was doing Rails
and then there are instances like
the web itself right
or Java
or
HTML which was originally built to
transmit physics papers right where
suddenly we look at a technology that was designed to do a very small thing
and realize that it's general
that it's solved
for a generic enough use case
for a generic enough scenario that there are actually a whole bunch of use cases
and I feel like WebAssembly
in the last
maybe 12-18 months
is experiencing
that kind of collective realization
as we all look at this and go
oh, you know, Fermion figured out a way to pull this out of the browser
and drop it in the cloud
oh, somebody else, you know, single store figured out how to pull this out of the browser
and drop it into their database
so that they can run stored procedures
that are compiled to WebAssembly
next to the data instead of selecting it all out
munging it and then shoving it back in
et on va en savoir
ces applications intéressantes
où WebAssembly
nous a donné
des capacités qu'on n'a pas avant
et
en même temps, on va en savoir
que, vous savez, Fermion, on va en savoir
on pense que nous avons le moment de la règle pour WebAssembly
on aime cet application serverless
que nous avons développée et en même temps,
on va en savoir que
nous avons trouvé le moment de la règle pour WebAssembly
il va y avoir des fonctions dans la database
et, vous savez,
l'extisme va en dire
nous avons écrit le dernier système de plugins
que vous n'aurez jamais besoin d'utiliser
et c'est écrit dans WebAssembly
donc nous avons tous expérimenté
la rencontre avec le succès ici et là
et les défis de la décision, mais aussi de dire
qu'est-ce que le futur de WebAssembly a vraiment de l'air
est-ce que c'est un technologie vraiment broad
est-ce que ça va trouver
une niche et est-ce que la niche, sur le point de nous tous,
va être quelque chose de la browser
c'est fun parce que
les choses se sont en train de se faire
mais c'est aussi fun parce que nous nous sommes
regardés pour la sort de
l'explosion conceptuelle de toutes les choses
qui peuvent être faites avec cette technologie
et nous nous regardons tout le monde y trouver
est-ce que c'est le bon moment
pour se résoudre à ce problème que j'ai eu
depuis longtemps
c'est intéressant, une des soucis qu'on a parlé
beaucoup de la podcast
est l'incentif de la complexité
quand nous nous avons développé les applications
et, vous savez, je pense que la question
de l'adaptation de l'Oubernete
était cette réponse pour ce
problème complexe
d'enregistrer et de déployer des workloads
mais les gens qui veulent
avoir une plus grande simplité
sont comme, je ne veux pas penser à ça
je veux juste penser à la code
et je pense que les fonctions
comme un service, le mouvement de plateformes
et l'EBS Lambda, les travailleurs de Cloudflare
ce genre de choses, vraiment
on a été entourés en des gens
comme nous pouvons avoir une même simple
expérience de développeur
où nous commoditons ces ressources
même plus tard
et je pense que c'est vraiment intéressant
que l'ASM se trouve un plus
pour le public
c'est cool de voir ça s'évoluer
c'est vraiment intéressant
et quand vous portez les fonctions serverlesses
comme Lambda
ou Azure, Cloudflare
ou des choses comme ça
c'est un cas où l'Assemblée Web
a un spot réel qui mèche bien
et part de ça c'est parce
que la idée serverlesses
parle de fonctions serverlesses
c'est une idée
c'est un moyen
que nous introduisons l'élegance
d'une zone où il y avait une complexité
en fait, j'ai eu
une surface de service de TLS
et de processus management
et de multithrédition et tout
pour prendre des requises de TDP
je vais juste faire une fonction
pour que l'environnement
ait un appel à mon fonction et que je le fais
et puis quand le appel s'entend
mon fonction commence
est donné les requises
processus de complication, se remettra
et s'arrête
maintenant, avant je parlais
de la chose qu'on était après était scale to zero
et l'Assemblée Web a été offert scale to zero
functions de services
sont une architecture de scale to zero
ideally
dans l'abstract, il devrait être un architecture de scale to zero
architecture
le moyen que nous avons
à la première wave
de services en fonction
était un peu clumsier car nous n'avons pas
Lambda a été construite sans WebAssembly
Lambda a été construite en train
d'une machine virtual architecture
qui, comme on l'a parlé, est vraiment la plus slowe
de la cloud compute
c'est le
des machines de virtual qui peuvent prendre
minutes pour s'entendre
et donc il y a tout ce
optimisation derrière les scènes
sur les plateformes comme Azure Functions
et AWS Lambda
et Google Functions qui sont
créées pour pré-warmer les choses
et les prendre toutes les épaules et les être prêts
et chaque fois qu'on commence à utiliser des mots
comme cuir les choses et pré-warmer
nous sommes dans la tête de nos mains
oh, la haine, la haine, c'est vrai
plus d'électro-sécutes
les compétences sont en train de s'adresser
quand elles peuvent faire quelque chose
des ingénieurs sont en train de
payer les choses et les autres de nous
sont en train de payer ces choses
les fonctions typiques
même avec toutes ces optimisations
elles sont encore en train de prendre
200 à 500 milliseconds pour les start-up
pour les langues AWS de la tier 1

comme on l'a déjà déclenché
100 milliseconds est quand votre user
commence à perdre l'intérêt
donc déjà nous sommes au-delà de la bounds
de la nature de l'usage
et pour cette raison, je pense que Lambda
n'a pas vraiment, ou bien,
des choses de service-lesses
n'ont pas été très bien déclinés
avec les pouvoirs de mettre
les plateformes de web en arrière
nous avons pu couvrir les choses
comme si c'était satisfait
mais la couvrir ne sent pas
comme si c'était finit
et je pense que l'Assemblée Web
a donné une avenue très intéressante
pour nous à commencer à construire
le premier version de services-lesses
dans lesquels
notre assemblée Web
en temps de start-up est
à peu près de 2 milliseconds
et vraiment notre avantage est
à 1 millisecondes pour commencer
avant d'execuer les instructions
et c'est le profil
si vous voulez avoir un page
qui servit à 99% au rank de page
Google et qui s'écoute bien sur SEO
et c'est incroyable
WebAssemblée a un truc à offerter
pour faire, en addition
d'autres, la sécurité
la paquette
et ce genre de choses
donc je pense que les applications
de services-lesses
sont un des places
où nous, à Fermion
pour construire des outils comme Spinn
peuvent vraiment faire des improvements vastes
et dire que, ici, c'est un premier
step pour pourquoi WebAssemblée
est cette troisième wave de computing cloud
qui va pouvoir speed-up
la performance
speed-up le processus de développement
pour soutenir une grande variety de languages
et puis, comme WebAssemblée
s'y mètre et on a des choses comme le modèle
de component, on va pouvoir
construire des applications
très intéressantes et suffisant
en utilisant WebAssemblée pour tout le temps
et l'une des choses qui est incroyable
c'est que, maintenant, vous pouvez construire
une application de services-lesses
en utilisant les languages que vous voulez
c'est un grand exemple de la technologie
avant de nous changer
on va parler de Fermion
on a parlé de plateformes hostes
vous avez construit une plateforme hoste
pourquoi vous utilisez Fermion et qu'est-ce que c'est ?
je pense que si tout le monde ne se fait pas
construire une plateforme hoste, ce n'est pas ce que nous faisons
le monde est entièrement...
nous voulons construire
Spinn est un outil de développement pour montrer
comment construire des applications WebAssemblées
nous voulons vraiment construire un endroit
qui pourrait exécuter ces applications
nous voulons faire cela de manière
très facile pour les gens pour essayer
de construire ces applications
nous avons une source d'open source
un outil de développement
Nomad, console, vault, Spinn
tout ce genre de choses où vous pouvez
installer le service en quoi que vous soyez
un outil de développement
mais c'est un processus de consommation
il va prendre un temps pour vous faire le setup
et vous devez maintenir ceci
nous voulons vraiment donner des développeurs
pour essayer de les faire
de manière à l'instant
de retourner à cette histoire de core
nous voulons aller de l'incursion
pour déployer l'application
dans deux minutes ou moins
66 secondes ou moins c'est ce que nous sommes
maintenant en train de faire
vous typez un commande, le Spinn est nouveau
il s'arrête votre projet
vous pouvez le construire, le WebAssemblée
vous le déploie et vous le vous

et vous vous vous vous vous vous
vous en vous vous vous vous vous vous
et c'est essentiellement
ce qu'on est maintenant
c'est une plateforme libre, c'est un BAT
il va s'éloigner
et c'est un peu rater
parce que quand vous avez
1000 ou 2000 applications
vous devez l'avoir à regarder le budget
mais je pense que ça va évoluer
dans le genre de choses
où le platform Fermion est en train de se coucher
pour quelques mois vous pouvez
augmenter votre plan
faire tous les Wiskers et Slats
que vous voulez, construire tout ce que vous voulez
comme application de service
ou de l'application de service
et si c'est vraiment plus votre chose
que vous voulez que vous manquez votre plateforme
il y a encore le Spinn & Fermion
un plateforme libre que vous pouvez faire
votre propre chose
je pense que c'est commendable
que vous avez tout le tech
essentiellement libre
si vous voulez vous hostez ça vous pouvez
je pense que c'est super cool
je pense que c'est en fait l'une des choses
qu'on a appris à Microsoft de tous les places
quand vous pensez à Helm
on n'a jamais tenté de moneter
Helm à Microsoft
le seul objectif de Helm
c'est de faire ça plus facile
pour les gens d'avoir le travail qu'ils ont voulu
ce qui, dans Helm's purview
c'est de la batterie de la jambe
et de la réutiliser les mêmes packages
pour installer votre software
sur des instances de Kubernetes
que vous avez vus
mais ce que nous avons observé c'est
quand vous donnez des gens un outil
qui fait que c'est plus facile pour eux
pour construire les choses qu'ils veulent
ils construisent plus de choses
par la plateforme
et AKS était le plus grand
service offert
AKS, le service de Kubernetes
le plus grand offert
dans tous les catalogues Azure
il y a des types de applications
et services à Azure
et AKS était l'un des plus grands
et la raison pour laquelle
j'ai été convaincu
c'est parce que nous avons
offert un whole bunch de tools
qui ont fait ça compétent
c'était facile de bouger
à l'un des petits applications
et les databases
et les stack monitoring
et tout ça, en utilisant des tools
comme Helm, pas exclusive
mais c'était l'une des tools
donc, nous avons regardé le Fermion
nous avons dit que nous sommes des développeurs
de la source d'envoi
mais nous voulons vraiment appeler
ce que nous voulons vraiment faire
ce que nous voulons vraiment faire
c'est que nous voulons vraiment
faire un tour de la source de la source
et nous voulons vraiment

et nous voulons vraiment

et nous voulons vraiment

et nous voulons vraiment
faire un tour de la source de la source
et nous voulons vraiment
et nous voulons vraiment
faire un tour de la source de la source
et nous voulons vraiment
faire un tour de la source de la source
et nous voulons vraiment
faire un tour de la source de la source
et nous voulons vraiment
faire un tour de la source de la source
et nous voulons vraiment





et ça c'est vraiment

avec ça on va nous faire des tour de la source de la source de la source
j'ai envie de entendre la toute interview
c'est juste de me faire peur
le président est très peur
c'est une des choses
où on doit avoir des gens
pour payer le passage au futur
et ça crée
on va faire des tools pour y aller
on apprécie
les works que tu as fait
j'ai expérimé les joies de Helm
donc pas avoir à refaire
je apprécie
les works que tu as fait
c'est un épisode super drôle
j'ai vraiment apprécié ce que tu as fait
c'est un lot de fun
