In this series of chaos engineering articles, let's discuss how to simulate CPU consumption to spike up to 100% on a host (or container). CPU consumption will spike up whenever a thread goes on an infinite loop. Here is a sample program from the open-source BuggyApp application, which would cause the CPU to spike up....

Buggy App – Simulate performance problems
Buggy App is a simple java application that simulates different performance problems like Memory Leak, OutOfMemoryError, CPU spike, thread leak, StackOverflowError, deadlock, unresponsiveness, ... Using this application, you can simulate various performance problems in your environment. Here are a few use cases where Buggy App can be used: a. You can configure and launch Buggy...
