Four Pillars of Service-Oriented Architecture
Grace A. Lewis, Dennis B. Smith · 2007
Abstract : A cornerstone of DoD policy for future software and systems policy is the migration of systems to net-centric operations. The net-centric vision requires the leveraging of a highly flexible set of capabilities that can be composed quickly and flexibly into applications that take advantage of the interoperable aspects of the web and provide effective mission value. Among current technologies, SOA has the greatest potential for implementing this vision. However, there is a great deal of con- fusion a bout what SOA is, whether it is real, and what it takes to implement a SO A-based system. This artic le provides a high-level introduction to SOA, and then outlines how a DoD organization can develop an effective strategy for implementing the vision.
