Building a server to manage high concurrent connections is non-trival task. For those developers that use ActionScript 3 to build games on the client side it means having a totally different skillset. Being able to use ActionScript 3 on the server to build MMO’s or port client code to the server allows developers to leverage their skills on the server.
By walking through a live game example with more then 15,000 concurrent connections running on a medium Amazon EC2 server the presentation will:
1. Introduce Linux server configuration for high concurrent connected usage.
2. Introduce Socket class based on libev library for high concurrent connection.
3. Introduce leveraging Tamarin project for ActionScript 3 on the server.
