Service Oriented Architecture (SOA) is an architectural style for building software applications that use services available in a network such as the Web. SOA is based on standard protocols such as HyperText Transfer Protocol (HTTP), Simple Object Access Protocol (SOAP), etc. SOA services are consumed by client applications over the Internet. SOA exposes business services to a wide range of service consumers. Assess SOA in terms of business integration, security,interoperability, and IT infrastructure.
