The Infrastructure Optimization service (Watcher) provides flexible and scalable resource optimization service for multi-tenant OpenStack-based clouds.
Watcher provides a complete optimization loop including everything from a metrics receiver, complex event processor and profiler, optimization processor and an action plan applier. 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 also supports a pluggable architecture by which custom optimization algorithms, data metrics and data profilers can be developed and inserted into the Watcher framework.
Check the documentation for watcher optimization strategies at Strategies.
Check watcher glossary at Glossary.
This chapter assumes a working setup of OpenStack following the OpenStack Installation Tutorial.
