An Erlang Streaming Media Server with Custom DDoS Defenses

We converted a large Java media server into Erlang in the space of a few months. The system performs better and more reliably than the Java system with less staff and maintenance issues.

Talk objectives:

This presentation will describe a first experience with functional programming.   We replaced a large Java system of 35,000+ lines of code with an Erlang system of less than 4000 lines.   A particularly interesting feature of the new system is the C++ module responsible for DDoS defense tied to the Erlang with Google Protobufs.  We will survey the key points of the Erlang system with particular emphasis on the DDoS module.

Target audience:

Anyone interested in real world examples of successful Erlang implementations.
