<p>Sorry for my ignorance, how does it differ from
<a class="moz-txt-link-freetext" href="http://erlangonxen.org/">http://erlangonxen.org/</a> (apart from its ability to run on bare
metal without Xen)? Does rumprun support ARM processors/boards?</p>
<p>IMHO both projects (Erlang on Xen / rumprun) suffer from a
similar problem as IoT. They look great on paper as technologies,
but it's hard to find an application in which they would be
useful. They might be just waiting for that great idea which will
allow them to break through and blow your mind.</p>
<p>I could imagine an application which scales nearly linearly with
the amount of nodes you allow it to use. When the capacity or
speed needs to be increased, you just provision new nodes, each
one a simple ARM module running Erlang, and you add it to the
cluster. The application then uses the new node and distributes a
bit of the running load to it.</p>
<p>It's not impossible from a technical point of view but it's hard
to imagine why a company would want to do that instead of moving
the system to a new server with more CPU/RAM. In any case it's
great that such an option exists and we can use it to try things.
Anyway, thanks for bringing it up, I wouldn't have known Rumprun
otherwise.<br>

<div style="font-size:12.8px">I did an initial port of Erlang on
the RumpRun unikernel (<a moz-do-not-send="true"
href="https://github.com/rumpkernel/rumprun-packages/tree/master/erlang"
target="_blank">https://github.com/rumpkernel/rumprun-packages/tree/master/erlang</a>)
in September last year. While the experience was enthralling,
there were after thoughts which remained unanswered. I wonder
what Erlang experts think regarding running Erlang on
unikernel. RumpRun unikernel is an great project which (in my
view) opened possibilities to design in some unique ways while
shifting aware from the traditional operation system based
design. There are some nuances like multi-threading instead of
providing multi-process (no fork), but I Erlang does play nice
(at least for the most part) with it. Needless to say the
energy spent and my lack of understand on Erlang internals
ensured that the project is suited for pet projects rather
than production (or any serious use).</div>
<div style="font-size:12.8px"><br>

<div style="font-size:12.8px">My choice Erlang is a bit biased
primarily it being my first experience to functional
programming language and a long history of working in the
telecommunications industry (though not using Erlang in
production as much I'd wanted to). The language is awesome for
many use cases though this email is primarily looking at its
play with unikernels. The language blew me away with the ease
and core language features for meeting complex requirements
like (though not limited to) scalablity, availability and
soft-real time behavior (not to mention the VMs capability to
magically load the system resources evenly) which takes a lot
of effort in implementing in traditional programming
languages.</div>
<div style="font-size:12.8px"><br>
</div>
<div style="font-size:12.8px">My initial motivation to attempt
the port was to look at role of Erlang (which pretty much does
most of stuff a traditional OS+utils would provide to regular
applications) in microservices architecture. In my opinion the
choice of RumpRun unikernel makes a lot of sense in this
respect rather than rely on traditional operating system
architecture. Having said that, I would like to hear opinions
from Erlang experts as to whether the marriage of Erlang with
Unikernel has a bright future :)</div>
