WASHINGTON - One of the U.S. government's strongest advocates of cloud computing is also one of its most secretive operations: the Central Intelligence Agency. Jill Tummler Singer, the CIA's deputy CIO, says that she sees enormous benefits to a cloud approach. But the CIA has adopted cloud computing in a big way, and the agency believes that the cloud approach makes IT environments more flexible and secure.
And while the CIA has been moving steadily to build a cloud-friendly infrastructure - it has adopted virtualization, among other things - cloud computing is still a relatively new idea among federal agencies. "Cloud computing as a term really didn't hit our vocabulary until a year ago," said Singer. For example, a cloud approach could bolster security , in part, because it entails the use of a standards-based environment that reduces complexity and allows faster deployment of patches. "By keeping the cloud inside your firewalls, you can focus your strongest intrusion-detection and -prevention sensors on your perimeter, thus gaining significant advantage over the most common attack vector, the Internet," said Singer. But now that the CIA is building an internal cloud, Singer sees numerous benefits. Moreover, everything in a cloud environment is built on common approaches. But there are limits.
That includes security, meaning there's a "consistent approach to assuring the identity, the access and the audit of individuals and systems," said Singer. The agency isn't using a Google model and "striking" data across all its servers; instead, data is kept in private enclaves protected by encryption, security and audits. And it has virtualized storage, protecting itself "against a physical intruder that might be intent on taking your server or your equipment out of the data center," said Singer. The CIA uses mostly Web-based applications and thin clients , reducing the need to administer and secure individual workstations. Speaking at Sys-Con Media's GovIT Expo conference today, Singer not only provided a rare glimpse into the IT approaches used by the agency, but also talked about one of its greatest challenges: the cultural change cloud environments bring to IT. A move to cloud environments "does engender and produce very real human fear that 'I'm going to lose my job,'" she said. Barry Lynn, the chairman and CEO of cloud computing provider 3tera Inc. in Aliso Viejo, Calif., said a typical environment may have one systems administrator for every 75 physical servers.
In practice, highly virtualized environments reduce the need for hardware administration and, consequently, for system administrators. In contrast, a cloud-based environment may have just one administrator for every 500 servers or more. Federal CIO Vivek Kundra is encouraging agencies to adopt cloud computing, and he recently opened an online apps store that enables federal agencies to buy cloud-based services from Google, Salesforce.com and other vendors. The CIA has "seen a significant amount of pushback, slow-rolling [and] big-process engineering efforts to try to build another human-intensive process on top of enterprise cloud computing," said Singer. "It will take us a good long while to break that." One thing the agency will do to address resistance will be to base contract competitions on performance, not head count, "where it's to [a service provider's] benefit to do the work with fewer bodies and make more profit for their company," said Singer. That's something the CIA will not do; its data will remain within the agency's firewalls, said Singer.
Obstacles to the adoption of cloud computing, including concerns about security and loss of data control, may slow momentum, but "I think we'll see broader adoption and higher spending after the administration makes progress in some of the pilot programs it has planned," said Peterson. Government market research firm Input has revised its forecast for federal cloud-related spending upward; it now expects the government's cloud expenditures to grow from $363 million this year to $1.2 billion by 2014. "I think this is probably a conservative estimate, considering the push from the administration," said Deniece Peterson, an analyst at Reston, Va.-based Input. Singer said the CIA's IT department was moving in the direction of cloud computing, even if it wasn't using that term, when it widely deployed virtualization technology. Abstracting the operating system and software from the hardware "is the foundation of the cloud," Singer said. "We were headed to an enterprise cloud all along."
