Erlang is a programming language used to build massively scalable systems with high availability.
Erlang/OTP (Open Telecom Platform) is a powerful development platform for building concurrent, distributed, and fault-tolerant systems. Designed for high availability and scalability, Erlang/OTP provides a runtime system, standard libraries, and design principles for creating robust applications. It's widely used in telecommunications, messaging systems, and real-time applications where reliability and uptime are critical. The platform's actor-based concurrency model and hot code swapping capabilities make it ideal for building systems that must run continuously without downtime.
