Erlang Processes
Erlang Processes are lightweight, concurrent execution units in the Erlang programming language, designed for building highly scalable and fault-tolerant systems. They operate independently with isolated memory, communicate via message passing, and are managed by the Erlang runtime system (BEAM), enabling massive concurrency with minimal overhead. This model is fundamental to Erlang's actor-based concurrency and underpins its reliability in distributed and real-time applications.
Developers should learn Erlang Processes when building systems requiring high concurrency, fault tolerance, and low-latency communication, such as telecommunications switches, messaging platforms, or distributed databases. They are essential for leveraging Erlang's strengths in handling millions of concurrent connections efficiently, as seen in use cases like WhatsApp's backend or financial trading systems, where reliability and scalability are critical.
