OTP is a set of useful middle-ware, libraries and tools written in Erlang. It is an integral part of the open source distribution of Erlang.
Erlang was originally developed in the Computer Science Laboratory at the Swedish Telecom company Ericsson. OTP stands for Open Telecom Platform which was a brand attempt before Ericsson released Erlang/OTP as open source. However neither Erlang nor OTP is specific to telecom applications.

It contains:

  • Erlang interpreter
  • Erlang compiler
  • A protocol for communication between servers (nodes)
  • Corba Object Request Broker
  • A static analysis tool called Dialyzer
  • A distributed database server (Mnesia)
  • Lots of libraries

Erlang/OTP has been used to build systems with 99.9999999% reliability (that’s nine nines).
