Resumen
Erlang is a language developed to let mere mortals write, test, deploy, and debug fault-tolerant concurrent software. Developed at the Swedish telecom company Ericsson in the late 1980s, it started as a platform for developing soft real-time software for managing phone switches. With the increasing importance of concurrent programming, Erlang is seeing growing interest and adoption. Indeed, Erlang is branded as a "concurrency-oriented" language. Several companies offer commercial products and services implemented in Erlang for telecom, electronic payment systems, and social networking chat. Erlang-based Web servers are notable for their high performance and scalability. Concurrent programming will never be easy, but with Erlang, developers have a chance to use a language built from the ground up for the task and with incredible resilience engineered in its runtime system and standard libraries. The standard Erlang implementation and its documentation, ported to Unix and Microsoft Windows platforms, is open source and available for free download from http://erlang.org
