Use Load Testing to Build a Proper Mental Model of Your Service

Wednesday, 30 August, 2017 - 15:4016:10

John Looney, Intercom


Large organisations often have teams dedicated to building and using load test frameworks for their production services. Intercom's engineering team was too small to have accurate load tests for all of it's systems, but as we acquired larger customers, having accurate load-test numbers, and being able to communicate them to the business became more critical. This talk will cover some things we learnt about load testing, and how it changed our mental models of some of our infrastructure.

He is now applying SRE to Intercom's infrastructure. He is passionate about ensuring that engineers know the best use of their time and energy, but still hasn't worked out how to not burn himself out occasionally.
