GCN : October 2012
GCN OCTOBER 2012 • GCN.COM 47 STAN BAROUH GCN AWARDS DOD ENTERPRISE EMAIL DEFENSE INFORMATION SYSTEMS AGENCY Led by its Defense Information Systems Agency, the Defense Department is roll- ing out an enterprise e-mail system with the goal of establishing a core of networks, data centers and Internet-like information services for 4.5 million users across the de- partment. The first phase of the program, called DOD Enterprise Email, includes migrat- ing the Army's enterprise e-mail users to a private cloud hosted by DISA's Defense En- terprise Computing Centers. To date, more than 500,000 Army users have moved to the new system, which is being built by teams from DISA and General Dynamics Information Technology. One of the biggest early hurdles the teams faced was how to deliver a system that could scale to 4.5 million users around the world while maintaining continuity of operations. The answer was to build incre- mentally so that the network is not relying on one or two primary components that could bring down the whole system if they failed. "The scale of the project demanded we understood the functional and technical requirements that are unique to DOD com- ponents while maintaining a service that could be adopted by the DOD Enterprise," said Paul Crumbliss, DISA program man- ager for DOD Enterprise Email. The system is based on unique modifi- cations to Microsoft Outlook, Windows Server 2008 and Exchange 2010, ensur- ing anytime, anywhere availability with a Common Access Card. It is also designed to bolster collaboration by giving users the ability to schedule meetings across the entire DOD enterprise. Another big plus is access to DOD's Global Address List, which contains information for all email users, distribution groups and Exchange resources. The system "facilitates DOD-wide infor- mation sharing and provides access to the Global Address List, regardless of users' organizational affiliation," Crumbliss said. "This allows email to serve as a collabora- tion tool that is essential to the day-to-day operations of our mission partners, who require access across the DOD enterprise to achieve their goals and missions." In addition to consolidating DOD's email infrastructure and centralizing email man- agement, DOD Enterprise Email will also save money, officials said. In a report to Congress the Army alone has identified more than $75 billion in savings in the first year. DOD Enterprise Email "is saving valu- able budget dollars by eliminating redun- dant resources," Crumbliss said, "freeing up the agency to focus on other critical functions within their organization." • --- Richard W.
