Multimedia Galore: Sending JPGs and 3GPs and AMRs!


By Erlang Central | Published: March 18, 2013



A very popular feature of the WhatsApp Messenger smartphone application is the ability to send images, videos, and audio notes to the smartphones of friends, family members, and groups. As one of our 2012 server projects, we replaced our original multimedia system with an Erlang-based system.  In this talk we will describe the architecture of the new system, some of the obstacles we encountered, and the scalability, functionality, and operability improvements that were achieved.

Talk objectives: To describe the challenges and opportunities in building a scalable multimedia store-and-forward system using Erlang.
Target audience: People interested in multimedia file serving using Erlang in a global-scale communications system.
