For now, the services are available only on a pre-release basis, but the space agency says it will release the capability to production within a few weeks, after the completion of a series of final spot checks called an Operational Readiness Review. Already, users are lining up: within the first 24 hours of pre-release, about 50 new projects fired up on Nebula, about a fifth of the 250 or so users that accessed Nebula during the entire summer of beta testing.
NASA Cloud Services will include storage and computing services initially, and were designed with research computing rather than either critical control systems or traditional IT apps in mind. "Our goal is to get scientists who would otherwise buy lab computers and give them an alternative where they can get up and running more quickly than buying things off the shelf," Chris Kemp, NASA's CTO for IT, said in an interview Tuesday. "We're trying to prevent people from buying unnecessary servers and infrastructure, and make their applications faster in speed and faster to provision."
Nebula is one of the cornerstones of government cloud computing, and has arguably attracted the most public attention of any federal cloud computing effort. NASA's announcement of its impending launch, which came the same day the General Services Administration announced that it will soon make a number of infrastructure-as-a-service cloud services available to government, indicates the progress the federal government is beginning to make toward actual adoption of cloud computing as opposed to simply hyping its potential.
Under the hood, Nebula was built on 10 Gig-E switching fabric at a major peering location for Tier 1 ISPs, and connects to high-speed academic and research networks CENIC and Internet2, thereby mitigating latency concerns. Each Nebula account comes with 100 Gbytes of storage, with more available. Its performance also rests on relatively high-end computing power.
