Dear list,

sorry for the repost, it turns out that I needed to relax my dmarc
settings [a] for this list to work properly. Please find the original
message below.

Cheers, Markus

Hi all,

I started writing OCaml recently, coming from a background of Scala and
Python. My interest was triggered by a HackerNews post announcing an
MOOC [1] for a language I never heard of before. As you might
comprehend, I was quickly pulled into this amazing world of global type
inference, multi-paradigm programming and native compilation.

Since my day job is heavily focused on cloud development, I also came
round to write some Go code. You can tell that this language is designed
for containers, but what struck me as odd were the many parallels that I
saw to OCaml - static compilation to native code, object oriented
programming, first-class functions. Made me wonder if OCaml would be a
good fit for running in, say, Kubernetes.

I wrote a simple TCP utility to accompany my mail server, which is
running on k8s, and after having dealt with some quirks I found that the
language and ecosystem fit the cloud-native paradigm quite nicely. It
also motivated me to write some of my findings up [2] and see if I can
come up with some cool use cases.

Are you deploying OCaml in containers? Are you aware of some libraries
and/or tooling to accelerate developing OCaml for the cloud?

Cheers, Markus

Dear Markus,

I am not sure that I understand what you are referring to. Kubernetes
(and the underlying Docker) is just a method for distributing code to
Linux. As OCaml compiles natively to Linux, it is a perfect fit from
that perspective.

For sure you can write servers in OCaml (though in direct comparison
with Go it only shines when you really can exploit its language features
- there are downsides like missing multicore capability - for that
reason we are currently developing a server in Go where some (complex)
functionality is handed off to OCaml and linked via FFI). Whether there
is some special language feature primarily useful in cloud environments?
I don't know, I guess this depends heavily on the application area.

Gerd

Hi Markus, check out https://mirage.io/

Anil Madhavapeddy's team has been working on the Mirage unikernel for
several years and they were recently acquired by Docker. The value
proposition is being able to compile a kernel and any other stack you need
right inside your server and spin up a new instance in a few milliseconds
as soon as a request comes in. Anil spoke about it in this classic episode
of the FLOSS Weekly podcast: https://twit.tv/shows/floss-weekly/episodes/302

Cheers,

Yawar
