OpenStack

OpenStack is a free and open-source software platform for cloud computing, mostly deployed as an infrastructure-as-a-service (IaaS). The software platform consists of interrelated components that control hardware pools of processing, storage, and networking resources throughout a data center. Users either manage it through a web-based dashboard, through command-line tools, or through a RESTful API. OpenStack.org released it under the terms of the Apache License.

OpenStack began in 2010 as a joint project of Rackspace Hosting and NASA. As of 2016 it is managed by the OpenStack Foundation, a non-profit corporate entity established in September 2012 to promote OpenStack software and its community. More than 500 companies have joined the project, including AppFormix, Arista Networks, AT&T, AMD, Avaya, Brocade, Canonical, Cisco, Citrix, Comcast, Cray, Dell, Dreamhost, EMC, Ericsson, Fujitsu, Go Daddy, Google, Hewlett-Packard, Hitachi Data Systems, Huawei, IBM, Intel, Internap, Juniper Networks, Mellanox, Mirantis, NEC, NetApp, Nexenta, OpenIO, Oracle, OVH, PLUMgrid, Pure Storage, Qosmos, Red Hat, Solidfire, SUSE, VMware, VMTurbo and Yahoo!.
