Services – Service Oriented Architecture

Competition for many organizations demand that the organization stays nimble enough to adapt their information technology systems to increase system productivity, data integrity, lower costs, and increase end-user productivity.  The problem that many organizations face today is that they are supporting a myriad of different systems and applications which makes exchanging data between applications and between systems very difficult if not nearly impossible.  Imagine if you will, trying to mesh legacy systems and applications with object-oriented applications, various databases and files, and various communication protocols.  Enter Service Oriented Architectures (SOA) and Web Services.

Service Oriented Architectures, through the implementation of XML and Web Services, allows an organization the means to start addressing the challenges described above.  “According to Gartner, SOA is ‘an application topology in which the business logic of the application is organized in modules (services) with clear identity, purpose and programmatic-access interfaces.  Services behave as ‘black boxes’:  their internal design is independent of the nature and purpose of the requestor.  In SOA, data and business logic are encapsulated in modular business components with documented interfaces.  This clarifies design and facilitates incremental development and future extensions.  An SOA application can also be integrated with heterogeneous, external legacy and purchased applications more easily that a monolithic, non-SOA application can.’ (Gartner IT Glossary) – Service Oriented Architecture – A New Alternative to Traditional Technology Integration – A White Paper by John Senor, President, iWay Software
