An Elixir program consist of a large number of lightweight, concurrent processes communicating with each other via asynchronous messages. A process receives and handles incoming messages, transforming its internal state in a functional way. Inside a process, all code is sequential. The VM running Elixir, BEAM, normally utilizes all cores of a modern CPU and schedules processes for execution. By running many concurrent processes you can maximize the performance of current hardware.

The distributed database built on SQLite
Fault tolerance and high availability with zero hassle

Why run rqlite?

rqlite combines the simplicity of SQLite with a fault-tolerant, highly available system. Whether you're deploying resilient services in the cloud or reliable applications at the edge, rqlite provides a developer-friendly database that's exceptionally easy to operate.

Icecream was created by SUSE based on distcc. Like distcc, Icecream takes compile jobs from a build and distributes them among remote machines allowing a parallel build. But unlike distcc, Icecream uses a central server that dynamically schedules the compile jobs to the fastest free server. This advantage pays off mostly for shared computers, if you're the only user on x machines, you have full control over them.
