About OpenStack
OpenStack is a collection of interoperable components that can be deployed together to provide computing, networking and storage resources. Those infrastructure resources are then exposed to end users through programmable APIs, so that capacity can be requested and managed by software rather than by hand. 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.
