Distribution to multiple virtual machines in the cloud or servers is the way to scale horizontally when there is no more room or resources to grow vertically. In this talk we will discuss how to load test an XMPP server and distribute load generation using Erlang/OTP as a platform. Experiences from testing production ready MongooseIM systems will be presented.

Talk objectives: show from the ground up how to plan and execute load tests of a distributed service and distribute load generation.

Talk audience: DevOps people wanting to load test their XMPP or other message oriented services. People evaluating XMPP solutions in terms of capacity and scalability.
