Introduction
Books
Computer books
Erlang/OTP concurrent programming practices focuses on Erlang development in the production environment, mainly explaining how to build stable, well-controlled, and maintainable product-level code, it has accumulated many years of practical experience from three Erlang masters.
Erlang/OTP concurrency Programming Practice is divided into three parts: the first part explains Erlang programming and OTP basics; the second part explains how to add OTP advanced features one by one in actual development to improve application, through the main project in this book-accelerating distributed cache applications for web access, the author elaborates on various skills in practice in a simple way. The third part discusses how to integrate code with other systems and users, and how to optimize the performance.
Erlang/OTP concurrent programming practices is intended for Erlang programmers and developers interested in Erlang/OTP.
