In his SLOConf talk Production load testing as a guardrail for SLOs and in his blog Production Load Testing, Hassy Veldstra, founder of artillery.io makes the case for load testing in production. It helped him in various organizations to establish SLOs (Service Level Objectives) and change the way engineers think about performance. He got inspired by Building Evolutionary Architectures which introduces the concept of performance as a fitness function.Tune in into our conversation, hear our arguments pro and contra load testing in the various environments and learn why in the end we agreed on the fact that SLOs – while nothing really new – are a great chance to re-define performance engineering.Linkedinhttps://www.linkedin.com/in/hveldstra/SLOconf: Production load testing as a guardrail for SLOs - by Hassy Veldstrahttps://www.youtube.com/watch?v=Y20K1mJB6tkBlog: Load testing.
