WebAssembly and Containers

[@TheDataMuseum]

Absolute game changer! Can't believe this hasn't been talked nearly enough as it should

7:25 "The characteristics that make it great for the browser also make it great for the cloud". Coincidence? I think not! You described cloud computing earlier as "running your code on someone else's computer securely", but that's *exactly* what a browser does. Putting JS or WASM into a webpage is, in a fact, a form of cloud computing - you are running your code on someone else's (the client's) computer.

Excellenet presentation, Now got the picture of Docker & Webassembly , This is like a fight between Apple Vs Microsoft in 90's ...Actually, truth is both does different things nd both needs to be there in the ecosystem serving different purpose.

What is the difference between wasm running in docker and a golang binary running in a scratch Docker container? I have a web server I wrote in Go in that scratch docker container with a resulting size of 7MB. This web server has served 100,000 requests and transferred 10 gigs of data in 34 seconds.

[@saidinesh5]

The wasm will still have to be run by an interpreter.. which is written in probably C++ or rust or even go. So it will obviously be slower than your go lang binary running in a scratch docker container. However, if your golang binary is supposed to serve requests based on code written by someone else.. you can use a webassembly interpreter inside your golang binary and load their code compiled to wasm and make those interpreters handle the incoming requests.

Somehow WebAssembly makes it feel like introducing compiled language to JavaScript developer for the first time ever whereas rest of the industry's been doing for years.

[@KManAbout]

Js developers have been doing compiling for years

I'm interested if docker containers could run in WASM in the browser one day. That would be truly amazing.

[@TheCardil]

Why would you like that? Browsers could run Wasm already without a Docker as middle man. Any middleman would only add overhead.

[@ryanleemartin7758]

You want docker containers to run in wasm in the browser? For what purpose? Isn't docker essentially isolating linux user space? It still needs a kernel to operate. Am I missing something? I'm intrigued but I don't grasp the concept

[@karelhrkal8753]

@@ryanleemartin7758 You could run programs that can be dockerized, but that do not compile to wasm. Also, I can just grab any docker container and just run it, I don't need to get the sources, optimize them for wasm, etc etc etc. Also, file IO could be implmeneted with local storage.

[@ryanleemartin7758]

@@karelhrkal8753 That sounds very cool but you'd still need a linux kernel. How could that work?

[@karelhrkal8753]

@@ryanleemartin7758 And what is Linux kernel implemented in? C, probably. And C can compile to WASM.

I don't know what it is, but containerization just scratches some weird itch. I love the idea of portable environments and static volumes. It almost feels transgressive lol

lovely

Now I know how Azure container apps can scale down to zero :)

Good grief! Your cat is GREEDY!

hey man, this is useless, you need to give 3 minutes high level overview with main points and not 25 minutes of useless blabbing without structure
