About OpenStack
OpenStack is a collection of interoperable components that can be deployed together to provide computing, networking and storage resources.

The project lives in the Python ecosystem and is released under the Apache 2.0 license, with development coordinated at opendev.org and documentation hosted at openstack.org.
