Gremlin brings Chaos Engineering as a Service to Kubernetes
The practice of Chaos Engineering developed at Amazon and Netflix a decade ago to help these web scale test their systems for worst case scenarios before they happened. Gremlin was started by a former employee of both these companies to make it easier to perform this type of testing without a team of Site Reliability Engineers (SREs). Today, the company announced that it now supports chaos engineering-style testing on Kubernetes clusters.
The company made the announcement at the beginning of KubeCon, the Kubernetes conference taking place in San Diego this week.
Gremlin co-founder and CEO Kolton Andrus says that the idea is to be able to test and configure Kubernetes clusters so they will not fail, or at least reduce the likelihood. He says to do this it's critical to run chaos testing in live environments, whether you're testing Kubernetes clusters or anything else, but it's also a bit dangerous to do be doing this. He says to mitigate the risk, best practices suggest that you limit the experiment to the smallest test possible that gives you the most information.
"We can come in and say I'm going to deal with just these clusters. I want to cause failure here to understand what happens in Kubernetes when these pieces fail. For instance, being able to see what happens when you pause the scheduler. The goal is being able to help people understand this concept of the blast radius, and safely guide them to running an experiment," Andrus explained.
In addition, Gremlin is helping customers harden their Kubernetes clusters to help prevent failures with a set of best practices. "We clearly have the tooling that people need [to conduct this type of testing], but we've also learned thro
