Highly distributed VoIP at Aptela – Cool features (and headaches)

By Erlang Central | Published: March 21, 2011

Aptela provides hosted communications services for small business. Our platform includes complex call routing, messaging, web-portals, mobile apps, PSTN/SIP access, and a coffee-grinder attachment. At peak, we handle dozens of calls – and an infinity of HTTP requests – per second

Last year we swapped out our (homegrown) EJB/Postgres based platform with a (also homegrown) highly distributed OTP/CouchDB based one. It wasn’t an easy switch given the peculiarities and pitfalls of designing for a call-processing world.

In this talk, I’ll describe our architecture and process model, with an emphasis on issues we’ve faced re: race-conditions, memory constraints, hot upgrades, all whilst accessing and working with extremely large amounts of data in a near-real-time manner.

Target audience: Anyone writing complex data-heavy distributed applications, and in particular distributed VoIP application developers (if there are any others out there!)

Talk objective: Describing the development and evolution of a complex call-processing environment, and the joys (!) of merging telephony with business applications in a highly distributed world
