Summary

Erlang solves one of the most pressing problems facing developers today: how to write reliable, concurrent, high- performance systems. It's used worldwide by companies who need to produce reliable, efficient, and scalable applications. Invest in learning Erlang now. Erlang is a programming language designed for building highly parallel, distributed, fault-tolerant systems. It has been used commercially for many years to build massive fault-tolerant systems that run for years with minimal failures. This book presents Erlang and functional programming in the familiar Pragmatic style. And it's written by Joe Armstrong, one of the creators of Erlang.
