OpenStack is a free and open-source software platform for cloud-computing, mostly deployed as an infrastructure-as-a-service (IaaS).〔(【引用サイトリンク】url= http://www.openstack.org )〕 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 of NASA. it is managed by the OpenStack Foundation, a non-profit corporate entity established in September 2012〔 〕 to promote OpenStack software and its community.〔 (【引用サイトリンク】url= http://wiki.openstack.org/Governance/Foundation/Mission )〕 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, Oracle, PLUMgrid, Pure Storage, Qosmos, Red Hat, Solidfire, SUSE Linux, VMware, VMTurbo and Yahoo!.〔 〕〔 〕〔 〕〔 〕〔 〕〔 〕〔 〕〔(【引用サイトリンク】url= http://www.enterprisenetworkingplanet.com/datacenter/avaya-looks-to-openstack-horizon-for-the-software-defined-data-center.html )〕〔 〕 The OpenStack community collaborates around a six-month, time-based release cycle with frequent development milestones.〔 (【引用サイトリンク】url= http://wiki.openstack.org/ReleaseCycle )〕 During the planning phase of each release, the community gathers for an OpenStack Design Summit to facilitate developer working sessions and to assemble plans.〔 (【引用サイトリンク】url= http://wiki.openstack.org/Summit )〕 Recent OpenStack Summits have taken place in Vancouver in May 2015 and in Paris in November 2014. The summit in May 2014 in Atlanta drew 4,500 attendees — a 50% increase from the Hong Kong Summit six months earlier. == History == In July 2010, Rackspace Hosting and NASA jointly launched an open-source cloud-software initiative known as OpenStack. The OpenStack project intended to help organizations offer cloud-computing services running on standard hardware. The community's first official release, code-named Austin, appeared four months later, with plans to release regular updates of the software every few months. The early code came from NASA's Nebula platform as well as from Rackspace's Cloud Files platform. In 2011, developers of the Ubuntu Linux distribution adopted OpenStack〔 〕 with an unsupported technology preview of the OpenStack "Bexar" release for Ubuntu 11.04 "Natty Narwhal".〔 〕 Ubuntu's sponsor Canonical then introduced full support for OpenStack clouds, starting with OpenStack's Cactus release. OpenStack became available in Debian Sid from the Openstack "Cactus" release in 2011, and the first release of Debian including OpenStack was Debian 7.0 (code name "Wheezy"), including OpenStack 2012.1 (code name: "Essex").〔 〕〔 〕 In October 2011, SUSE announced the public preview of the industry's first fully configured OpenStack powered appliance based on the "Diablo" OpenStack release. In 2012, Red Hat announced a preview of their OpenStack distribution, beginning with the "Essex" release. After another preview release, Red Hat introduced commercial support for OpenStack with the "Grizzly" release, in July 2013.〔 〕 In July 2013, NASA released an internal audit citing lack of technical progress and other factors as the agency's primary reason for dropping out as an active developer of the project and instead focus on the use of public clouds. This report is contradicted in part by remarks made by Ames Research Center CIO, Ray Obrien. In December 2013, Oracle announced it had joined OpenStack as a Sponsor and planned to bring OpenStack to Oracle Solaris, Oracle Linux, and many of its products.〔(【引用サイトリンク】url=http://www.oracle.com/us/corporate/press/2079843 )〕 It followed by announcing Oracle OpenStack distributions for Oracle Solaris〔(【引用サイトリンク】url=http://www.oracle.com/us/corporate/pressrelease/solaris-11-2-042914 )〕〔(【引用サイトリンク】url=http://www.oracle.com/us/corporate/press/2254736 )〕 and for Oracle Linux using Icehouse on 24 September 2014.〔(【引用サイトリンク】url=http://www.oracle.com/us/corporate/press/2298602 )〕 In May 2014, HP announced HP Helion and released a preview of HP Helion OpenStack Community, beginning with the IceHouse release. HP has operated HP Helion Public Cloud on OpenStack since 2012.〔(【引用サイトリンク】url=http://www8.hp.com/us/en/hp-news/press-release.html?id=1668354#.U-0sMmN7RpQ Press Release )〕 At the 2014 Interop and Tech Field Day, software-defined networking was demonstrated by Avaya using Shortest path bridging and OpenStack as an automated campus, extending automation from the data center to the end device, removing manual provisioning from service delivery.〔(【引用サイトリンク】date=26 March 2014 )〕 As of March 2015, NASA still makes use of OpenStack private cloud and has RFPs out for OpenStack public cloud support. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「OpenStack」の詳細全文を読む スポンサード リンク
