Elixir
Elixir is built on the foundation laid by Erlang/OTP. It runs on a virtual machine called BEAM.
The BEAM is built to run in a distributed fashion. It has its own scheduler and a facility to spawn light-weight processes which are not OS threads. Those processes are isolated and they communicate through message passing.
OTP (The Open Telecom Platform) was designed to build telecom systems at Ericsson.
