OpenStack, the open source cloud computing platform that allows enterprises to essentially run their own version of AWS in their data centers, was founded by NASA and Rackspace in 2010. Today, it’s being used by the likes of Comcast, PayPal, Volkswagen, CERN, AT&T, China Mobile and Her Majesty’s Revenue and Customs in the U.K. The OpenStack Foundation’s bi-annual developer conferences now regularly attract thousands of developers and while the project started with only a few core services (compute, storage and networking), it now features six core services and about 60 small projects under its umbrella.
