Openstack : An Overview

OpenStack is open source software for building clouds. Created to drive industry standards, end cloud lock-in and speed cloud adoption, OpenStack is a common, open platform for both public and private clouds with the support of over 160 industry leading companies, more than 3,000 global project participants and 100,000+ downloads. The open source cloud operating system enables businesses to manage compute, storage and networking resources via a self-service portal and APIs on standard hardware at massive scale.

Back in July 2010, Rackspace Hosting and NASA jointly launched a new open-source cloud initiative known as OpenStack. The ultimate goal was to enable any organization to create and offer cloud computing services that run on standard hardware. Since that date, approximately six revisions of OpenStack have been released, and more than 150 companies have signed up to support the platform.
