The Defense Department needs a fresh new approach to running its information technology (IT) systems. One idea is platform-as-a-service (PaaS) cloud computing, which would reduce the number of stovepipe systems. The biggest challenge ahead: convincing department decision makers to accept PaaS as a solution and to encourage its funding. The first step is separating the defense infrastructure from the applications, according to Paul A. Strassmann in his article, "Two Barriers Block New Architecture" in this issue of SIGNAL Magazine.
The computing device shouldn't matter, nor its provider: Defense Department personnel just want their information securely, by authorized channels, in a timely manner. Department customers want personal information assistants (PIAs), adapted to their position, training level and necessary connections. Paul A. Strassmann discusses the potential way forward in his article, "A Culture Shock Is Coming," in this issue of SIGNAL Magazine.
