Erlang for Scalable Insatant Messaging

Devcon June Conference, Thursday, June 20, 2013, 15:30

ooVoo’s instant messaging solution is an Erlang-based implementation of XMPP server (eJabberd) with focus on performance and scalability. Specifically designed for high end service provider’s purposes, it is fault-tolerant, distributed and can utilize resources of multi-core CPUs. It provides support for multiple client platforms, including WebSockets, reliable message delivery in mobile networks and in-game multi-user chats. Its modular architecture allows customizing it to cater to specific needs like in-house authentication or application-specific traffic such as VoIP signaling. Alexander Fok, System Architect at ooVoo, will present ooVoo’s implementation of highly scalable and high performance messaging solutions. The presentation will cover:

- eJabberd – current service implementation
