- Erlang
Erlang is a general-purpose concurrent, garbage-collected programming language and runtime system.
It was designed by Ericsson to support distributed, fault-tolerant, soft-real-time, non-stop applications.
It supports hot swapping, so that code can be changed without stopping a system.
The name "Erlang", attributed to Bjarne Däcker, has been understood as a reference to Danish mathematician and engineer Agner Krarup Erlang, and (initially at least) simultaneously as an abbreviation of "Ericsson Language".
Erlang was designed with the aim of improving the development of telephony applications. The initial version of Erlang was implemented in Prolog and was influenced by the programming language PLEX used in earlier Ericsson exchanges.

- What is Erlang?
Erlang is a programming language used to build massively scalable soft real-time systems with requirements on high availability.
Some of its uses are in telecoms, banking, e-commerce, computer telephony and instant messaging.
Erlang's runtime system has built-in support for concurrency, distribution and fault tolerance
