This week, there was an internal discussion at Aditi about Netflix's Chaos Monkey tool and the usefulness of such a tool for Windows Azure developers. I decided to build a simple version of this tool called WazMonkey. The code is available on GitHub: github.com/smarx/WazMonkey.
For those who don't know, Chaos Monkey helps AWS developers test the resilience of their applications by terminating EC2 instances at random. WazMonkey does something similar: it chooses a role instance at random from a Windows Azure cloud service and reboots it (or, optionally, reimages it).
See the usage info below:
