With Erlang's emphasis on highly parallel and fault-tolerant distributed systems, it has become an important language for any developer involved in writing concurrent, high-performance systems today. Mastering Erlang will help you become a master of Erlang, taking your skills to a professional level with the language and the real-world systems you'll find yourself working in with it. So if you're involved in a project where concurrency and high performance are key, the techniques in Mastering Erlang will take your Erlang skills to the level you need to succeed in the real job. Mastering Erlang takes you beyond the basics of the Erlang programming language, looking straight into key real-world topics of writing production code, debugging, and actually deploying Erlang systems--as well as upgrading them. You'll learn how to work with Mnesia, and you'll find drill-downs into drivers and OTP modules. Takes your Erlang skills to professional, real-world levels Explains the operations and ecology behind OTP Shows how to build, deploy, and upgrade reliable distributed systems Shows you how to debug and profile live Erlang systems What you'll learn How to work with Erlang in the real world Why you should deploy OTP behaviors How Mnesia really works How to work with Paxos and other Erlang clustering technologies in the real world How to debug a live cluster How your cluster can repair itself How to write production-quality Erlang code Who is this book for? You have learned some Erlang, but now you would like to become proficient at it, and you're ready for a professional environment. You might like to know what the OTP in Erlang/OTP is about. Or you are an Erlang programmer who has written a single-node system and you would like to add distribution and fault tolerance to your code. Or you would like to write a production-ready system from scratch. In all these cases, this is the book to have.
