OpenStack® is an open source software platform for private clouds and public clouds. As an Infrastructure as a Service (IaaS) platform, OpenStack enables companies to easily and efficiently add servers, storage and networking components to their cloud.
OpenStack History and Reach
Together, Rackspace and NASA launched OpenStack as an open source cloud software project in 2010. Today, OpenStack is managed by the nonprofit OpenStack Foundation. Rackspace is a platinum sponsor of the foundation and is actively involved with the OpenStack community.
OpenStack is the cloud platform of choice for some of the world’s largest companies. OpenStack powers Walmart’s ecommerce site serving 80+ million people each month. CERN, the European research organization, also uses OpenStack for its private cloud — the largest OpenStack cloud in the world, with nearly 200,000 cores.
