This is particularly important when operational issues arise as our engineers need to be able to quickly diagnose problem areas and work to correct them. Operational issues, however, are just one potential use cas

The above diagram expands on a previous post announcing Sp

chaosmonkey — Chaos Monkey is a resiliency tool that helps applications tolerate random instance failures. The Freedom and Responsibility culture at Netflix doesn’t have a mechanism to force engineers to architect their code in any specific way. Instead, we found that we could build strong alignment around resiliency by taking the pain of disappearing servers and bringing that pain forward. We cre
