Erlang is a programming language traditionally 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.
Some highlights of Erlang include:
- Simple and consistent error recovery and supervision
- Built-in fault tolerance
- Software upgrade (hot code loading) during runtime
- Run on a variety of platforms, supports heterogeneous networks.
- Network aware runtime, out-of-the-box distributed architectures
- Lightweight processes, highly scalable transparent or explicit concurrency
- Transparent Multi-core Support
- Functional programming language, high abstraction level, concise readable programs.
- 4–20 times less code compared to C/C++/Java
- Suitable for rapid prototyping
- Powerful middleware and libraries (OTP)

“The world is concurrent. Things in the world don’t share data. Things communicate with messages. Things fail”
