The Department of Homeland Security says it now has 12 separate cloud services available for use in federal agencies, and all but one of them have received full federal security certification. Examples include DHS’s Sharepoint-as-a-service offering, which already supports about 30,000 users in a public cloud setting. And more than 11,000 people are using the department’s email-as-a-service in the DHS private cloud. 70 percent of the department’s websites have moved to the DHS public cloud, and 100 applications are using a shared, cloud based identity management system.
