Erlang (/ ˈ ɜːr l æ ŋ / UR-lang) is a general-purpose, concurrent, functional high-level programming language, and a garbage-collected runtime system.The term Erlang is used interchangeably with Erlang/OTP, or Open Telecom Platform (OTP), which consists of the Erlang runtime system, several ready-to-use components (OTP) mainly written in Erlang, and a set of design principles for Erlang ...
OTP is a collection of useful middleware, libraries, and tools written in the Erlang programming language.It is an integral part of the open-source distribution of Erlang. . The name OTP was originally an acronym for Open Telecom Platform, which was a branding attempt before Ericsson released Erlang/OTP as open sou
List comprehension is a syntactic construct available in some programming languages for creating a list based on existing lists. It follows the form of the mathematical set-builder notation (set comprehension) as distinct from the use of map and filter functions.
As of 2009, it is one of the most popular open source applications written in Erlang. [4] XMPP: The Definitive Guide ( O'Reilly Media , 2009) praised ejabberd for its scalability and clustering feature, at the same time pointing out that being written in Erlang is a potential acceptance issue for users and contributors.

Elixir is a functional, concurrent, high-level general-purpose programming language that runs on the BEAM virtual machine, which is also used to implement the Erlang programming language. [3] Elixir builds on top of Erlang and shares the same abstractions for building distributed, fault-tolerant applications.
The LYME and LYCE software bundles are based on Erlang and comprise Yaws. They are composed entirely of free and open-source software. Yaws (Yet another web server) is a web server written in Erlang by Claes (klacke) Wikström. Yaws can be embedded into other Erlang-based applications or run as a regular standalone web server. [2]
Implementation in Erlang confers an efficiency benefit because of the use of a single virtual machine throughout an application. LYME makes use of this, since the Yaws web server is also implemented in Erlang. Address space is shared (although safely so, under Erlang) between code and data, including Mnesia's table data.

Agner Krarup Erlang (1 January 1878 – 3 February 1929) was a Danish mathematician, statistician and engineer, who invented the fields of traffic engineering [2] [3] and queueing theory. [ 3 ] Erlang's 1909 paper, and subsequent papers over the decades, are regarded as containing some of most important concepts and techniques for queueing theory.
