Elixir is a dynamic functional language based on almost 30 years old Erlang language and platform. Erlang is used in the systems that require high throughput and reliability (uptime). Examples of such systems are telecom servers and also big Internet apps like WhatsApp. Elixir is running on Erlang's virtual machine called BEAM. Elixir author José Valim got inspiration from languages like Ruby, Clojure and of course Erlang. For web development with Elixir there has recently been released a version 1.0 of Phoenix framework. Phoenix and Elixir combination is distringuished by µS response times, short and long term productivity, advanced failure handling and much more.
