美国电话电报公司（AT&T）于周一与OpenStack云正式签约，OpenStack云是Rackspace和美国国家航空航天局共同创建的开源云计算项目。

在拉斯维加斯举行的AT&T开发者峰会上，美国国家航空航天局显示了对OpenStack的忠诚。加入AT&T标志着OpenStack的第一次运输政变，而这仅仅用了18个月的时间。

自去年年初就有流言称AT&T 已经与OpenStack进行合作，并且在AT&T 首席技术官John Donovan的博客中得到官方证实。

他写道：“我们今天还宣布了AT&T已经成为美国第一个加入OpenStack的电信服务供应商，OpenStack拥有全球140多家技术公司。我们已经加入OpenStack一年之久并且已经为OpenStack的潜在新功能规划了蓝图，着眼于事务性任务管理。”

Donavan又说道：“如今我们正在把专用基础设施上的OpenStack功能加入到AT&T位于达拉斯、圣地亚哥和新考克斯新泽西州的数据中心。我们计划在2012年让双倍的数据中心具有开源功能。”

AT&T加入了OpenStack145多家公司的行列，其他主要IT企业包括思科、Citrix、戴尔、惠普、英特尔。

OpenStack现在正式发行了第四版本，名为Diablo，自从2010年7月发行此项目起，开源企业已经得到了从自身资料库中超过5万的下载量并且吸引了300多位活跃的开发者。

AT&T 的加入正值OpenStack云产品组合持续增长之时。云管理供应商Zenoss十一月的一项包括了几百位调查OpenStack与会者的调查发现，73的受调查者正在考虑使用OpenStack部署，43%的人计划一年内在OpenStack实现运行。

AT&T与OpenStack的合作也是推动云计算的另一个发展，在这其中主要的服务供应和载体正在通过收购（如Verizon收购Terremark）或是大笔的云投资把服务范围扩大到云领域。

除了公布与OpenStack的合作外，AT&T在周一还列出了云开发者计划。AT&T展示了AT&T云架构，它是一个以开发者为中心，使开发者划算的得到灵活、综合的计算和应用开发服务的云。

“云架构将提供一套强大的选项和配置，”他写道。“你将能够安装公共和私有计算实例或者选择用裸机或是专用服务器选项自始至终的进行构建。云架构将在几周后投入应用，我们也将全年扩展以开发者为中心的服务供应。”

AT&T on Monday officially signed on with the OpenStack cloud, the Rackspace- and NASA-created open-source cloud computing project.

The major carrier revealed its OpenStack allegiance during its AT&T Developer Summit in Las Vegas. Adding AT&T marks the first carrier coup for the OpenStack play, which just hit the 18-month mark.

AT&T has been rumored to be working with OpenStack since early last year and in a blog post, John Donovan, AT&T's CTO, made it official.

"We also announced today that AT&T has become the first U.S. telecom services provider to join the OpenStack initiative, a community of more than 140 technology companies worldwide," he wrote. "We've been participating in OpenStack for more than a year and have already contributed a blueprint for a potential new function within OpenStack, focused on transactional task management.

"We’re housing our OpenStack capabilities on dedicated infrastructure in three AT&T data centers today, with locations in Dallas, San Diego and Secaucus, New Jersey," Donavan continued. "We plan to more than double the number of our centers with open-source capabilities in 2012."

AT&T joins the ranks of other major IT players like Cisco, Citrix, Dell, HP, Intel and others that comprise the now more than 145 companies that participate in OpenStack.OpenStack is now in its fourth official release, called Diablo, and since the project's launch in July 2010 the open-source cloud initiative has experienced well over 50,000 downloads from its own repository and has enticed more than 300 active developers.

AT&T joining OpenStack also comes as OpenStack's cloud profile continues to grow. A recent survey by cloud management vendor Zenoss, which polled several hundred attendees at the OpenStack Conference in October, found that 73 percent are considering some kind of OpenStack deployment and that 43 percent plan to be operational on OpenStack within a year.

AT&T pairing with OpenStack is yet another development in the carrier push into cloud computing, in which major service providers and carriers are broadening their offerings to include the cloud, either through acquisition, like Verizon's purchase of Terremark, or massive monetary cloud investments.

In addition to unveiling its OpenStack partnership, AT&T on Monday also outlined plans for cloud developers. AT&T showcased AT&T Cloud Architect, a developer-centric cloud that gives developers cost-efficient access to flexible, integrated computing and app development services.

"Cloud Architect will provide a powerful set of options and configurations," he wrote. "You'll be able to set up a public and private computing instances or choose to build from the ground up with our bare metal or dedicated server options. Cloud Architect will be available in coming weeks, and our developer-centric service offers will expand throughout the year."
