The document discusses OpenStack, a cloud operating system that manages compute, storage, and networking resources in a datacenter, initiated by NASA and Rackspace in 2010. It provides an overview of OpenStack's modular components, including core projects like Nova, Neutron, Cinder, and Glance, along with deployment methods and supported distributions. The document also mentions the latest releases and services available through various vendors that offer their own OpenStack solutions.

8. Components
Overview

9. OpenStack as a modular cloud
OpenStack is a modular collection of cloud components.
Each of these components, which are also known as projects, is
a collection of services that handles an IAAS resource such as
compute, networking and authentication.
There is a vast variety of projects out there,
You just need to choose.

30. OpenStack distributions
OpenStack is a free open-source platform.
As such, It doesn't have an on-call support or an official advisor.
OpenStack can also be consumed through vendors that
repacked OpenStack into their own distribution.
These vendors include RedHats OSP, Ubuntu OS,
SUSE OSC, Mirantis and even VMware’s VIO.
