In theory, it's a slam dunk: Public sec- tor IT managers run dozens of virtual ma- chines on a core set of physical devices, vastly reducing the server footprint and costs of the typical data center. Virtualiza- tion also improves hardware usage and creates a stepping stone toward the cloud. It also provides options: A hardware-in- dependent virtualized application -- from simple email to an enterprise resources planning system -- can readily move BUILDING BLOCKS OF THE NEW GOVERNMENT DATA CENTER Agencies are turning to flexible data center approaches, including converged, modular and software-defined systems, to meet their specific requirements and mission BY JOHN MOORE east Michigan region. The department is now revamping its data center to better support its shared services model. "We are architecting our data center to allow for more of those sharing opportu- nities to exist," said Phil Bertolini, deputy county executive and CIO of Oakland County. Accordingly, agencies are revisiting their physical infrastructure. The result is a re-architecting of the physical data center, including servers, storage and net- working, as agencies seek to harness new technologies including converged infra- structure, higher-speed connectivity and software-defined products. This renewed emphasis on physical devices may seem like a hardware renais- sance, but the cloud is very much a part of these new data center overhauls. In these cases, organizations may view the cloud as a resource to soak up spikes in data center workload or as a disaster recovery (DR) utility. The City of Asheville, N.C., for example, among an organization's servers or mi- grate outwardly to the cloud. But not all applications are departing for the cloud, at least at this point. Public safety systems and financial ap- plications, for example, continue to live within the four walls of the government enterprise. In addition, some agencies plan to offer shared services to other gov- ernment entities on a private cloud basis. And hardware remains important in such scenarios. For example, Oakland County, Mich.'s Department of Information Technology provides services to government offices inside the county and within the south- 20 GCN AUGUST 2014 • GCN.COM
