Developing Service Oriented Computing Model Based On Context-Aware
SOA and Cloud Computing are making major changes in the way companies build and deploy applications. The challenge is to meet the business expectation of faster delivery of new functionality, while at the same time maintaining control of application performance and availability across a growing network of service providers. SOA facilitates the development cycle by providing common features to everyone. However, SOA has some disadvantages such as the lack of information of what a service can provide and how can we discover it. When working with web services, the number of exposed methods or functions becomes a problem for developers. We do not need to deal with whole services if a developer needs to call one function. This article suggests and validates a new selected service model for the SOA. The layout presentation and the communication is described between client and services.
