Resilience testing is similar to disaster recovery testing because youre testing what happens when infrastructure fails, but the difference is that in resilience testing, youre expecting your application to keep running, with little or no downtime. With disaster recovery testing, some downtime is expected. One common testing scenario is to terminate a random instance within an autoscaling instance group. Netflix created software called Chaos Monkey that automates this sort of testing. If your application in the autoscaling instance group is stateless, then it should be able to survive this sort of failure without any noticeable impact on users.
