=================================== Infrastructure Optimization service =================================== .. toctree:: :maxdepth: 2 get_started.rst install.rst verify.rst next-steps.rst 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 https://docs.openstack.org/watcher/latest/strategies/index.html Check watcher glossary at https://docs.openstack.org/watcher/latest/glossary.html This chapter assumes a working setup of OpenStack following the `OpenStack Installation Tutorial `_.
