# Valet

Valet gives OpenStack the ability to optimize cloud resources while simultaneously meeting a cloud application's QoS requirements. Valet provides an api service, a placement optimizer (Ostro), a high availability data storage and persistence layer (Music), and a set of OpenStack plugins.

**IMPORTANT**: [Overall Installation of Valet is covered in a separate document](https://github.com/att-comdev/valet/blob/master/doc/valet_os.md).
