SOA and Web Services

       

Service Oriented Architecture (SOA) is a new architecture for the development of loosely coupled distributed applications. In fact service-oriented architecture is collection of many services in the network. These services communicate with each other and the communications involves data exchange & even service coordination. Earlier SOA was based on the DCOM or Object Request Brokers
(ORBs). Nowadays SOA is based on the Web Services. Broadly SOA can be classified into two terms: Services and Connections.

  • Services:
    A service is a function or some processing logic or business processing that is well defined, selfcontained, and does not depend on the context or state of other services.
     
  • Connections:
    Connections means the link connecting these self-contained distributed services with each other, it enable client to Services communications. In case of Web services SOAP over HTTP is used to communicate the between services.
     
  • Different Technologies Used:
    SOA is much different from point-to-point architectures. SOA comprise loosely coupled, highly interoperable application services. These services can be developed in different development technologies (such as Java, .NET, C++, PERL, PHP), the software components become very reusable i.e. the same C# (C Sharp) service may be used by a Java application and / or any other programming language.
