In computing, the term Service-Oriented Architecture (SOA "es-ō-ā") expresses a perspective of software architecture that defines the use of services to support the requirements of software users. In an SOA environment, resources on a network are made available as independent services that can be accessed without knowledge of their underlying platform implementationChannabasavaiah, Holley and Tuggle, Migrating to a service-oriented architecture, IBM DeveloperWorks, 16 Dec 2003
Service Oriented Architecture was first proposed by Roy W. Schulte and Yefim V. Natis who were Gartner analysts. They specified SOA as "a style of multitier computing that helps organizations share logic and data among multiple applications and usage modes." Roy W. Schulte and Yefim V. NatisService Oriented Architecture,Gartner, 12 April 1996
SOA is usually based on Web services standards (e.g., using SOAP or REST) that have gained broad industry acceptance. These standards (also referred to as Web service specifications) also provide greater interoperability and some protection from lock-in to proprietary vendor software. However, one can implement SOA using any service-based technology.
