Leveraging Federal IT Investment Using SOA
SOA builds on computer engineering approaches of the past to offer an architectural approach for enterprise systems, oriented around the offering of services on a network of consumers. A focus of this service-oriented approach is on the definition of service interfaces and predictable service behaviors. A set of industry standards, collectively labeled “Web Service” standards in this paper, provide and implement the general SOA concept and have become the predominant set of practical tools used by enterprise engineers for current SOA projects. Some Web Service standards have become foundational and more widely adopted, while many are still seeking broad industry or Government acceptance.
A Perspective on Emerging Industry SOA Best Practices (Executive Version)
Using a Service-Oriented Architecture (SOA) approach allows organizations to become both more efficient in meeting their current needs and more agile in meeting future—and possibly unknown—challenges. SOA, however, is not a panacea. As with any large-scale systems integration effort, there are challenges with employing SOA techniques effectively. This article presents industry best practices to deal with key SOA challenges.
A Perspective on Emerging SOA Best Practices
Service-Oriented Architecture (SOA) practices are intended to create an agile, integrated information technology (IT) infrastructure that is scalable, reliable, and can rapidly respond to an organization’s changing needs by employing loosely coupled and dynamic services. An SOA approach enables business needs to drive an organization’s strategic IT decisions. As a result, SOA allows a business to become more efficient in meeting its current business needs and more agile in meeting future (and possibly unknown) business needs. It is important to note, however, that an SOA is neither a panacea nor something that can be purchased. There are challenges with employing SOA techniques effectively, some of which are explored in this paper.
