Web Services  & Grid Computing

Web services are Internet-based, modular applications that perform a specific business task and conform to a particular technical format. The technical format ensures each of these self-contained business services is an application that will easily integrate with other services to create a complete business process. This interoperability allows businesses to dynamically publish, discover, and aggregate a range of Web services through the Internet to more easily create innovative products, business processes and value chains. 

For Web Services architecture, XML plays a role of normalizing the exchange of business data among trading partners by providing cross-platform approach in the areas of data encoding and data formatting. Simple Object Access Protocol (SOAP), built on XML, defines a simple way to package information for information exchange across system boundaries. Universal Description, Discovery and Integration (UDDI) Registries, on the other hand, allow programmable elements to be placed on Internet where others can access remotely. A typical usage of Web Services is Dynamic e-business integration, which is the dynamic adaptation of business processes and associated systems to support changing business scenarios. 

Building on both Grid and Web services technologies, the OGSA (Open Grid Services Architecture) is a distributed interaction and computing architecture based around the Grid service assuring interoperability on heterogeneous systems. It leverages the emerging Web Services to define the WSDL interfaces. All services adhere to specified Grid service interfaces and behaviors. The Grid can be defined at Enterprise level (Enterprise Grid), Partner level (Partner Grid) and Service level (Service Grid). On the other hand, the OGSA is a model for system composition. The Grid Computing is the key to advancing e-business into the future and the next step in the evolution of the Internet towards a true computing platform. In general, companies offering grid-based Web Service will tap new revenue streams as valuable data created on a grid system becomes information that can be sold via Web Service to partners or subscribers.
