This provides a robust framework to realize a wide range of cloud optimization goals, including the reduction of data center operating costs, increased system performance via intelligent virtual machine migration, increased energy efficiency and more!

- watcher - is the main repository. It contains code for Watcher API server, Watcher Decision Engine and Watcher Applier.
- python-watcherclient - Client library and CLI client for Watcher.
