What is Erlang?

Erlang is a functional, general-purpose programming language that excels in building scalable and concurrent systems. It handles high traffic levels, remains resilient to errors, and efficiently executes real-time tasks.

Erlang is your go-to choice for creating reliable, high-performance solutions.

Erlang history: Decades of success and counting


Erlang has come a long way since its first origin decades ago — and what made it successful in the past continues to empower it today.

It all started in the ’80s. Back then, the most advanced tech systems were primarily found in telecommunications, or more precisely, in telephone switching systems. The challenge was finding the perfect technology to support these systems, specifically their need for handling many simultaneous operations.

Engineers Joe Armstrong, Robert Virding, and Mike Williams met this challenge excellently
– they created Erlang. It was designed as a “write once, run forever” solution, enabling the development of highly reliable and fault-tolerant telephone switching systems. Soon after, Erlang’s purpose extended to various other domains, and the language became open-source and widely embraced in the tech world.

Today, you can leverage Erlang’s exceptional capabilities across various fields, including banking, e-commerce, social platforms, and more. This technology stands as your ideal ally for constructing solutions that thrive in modern environments.

Why use Erlang: Key features
