Providing Interoperability for Resource Access Using Web Services

This paper focuses on resource virtualization and interoperability required in the context of large distributed environments such as clouds and grids in which shared resources located on multiple sites are accessed by multiple users. A resource is exposed as a Web service. Techniques for handling two types of resources, a computing resource and a database resource are described. Two different Web service technologies, one based on SOAP and the other on REST are experimented with. A comparison of the two technologies including a performance comparison of two implementations (one using SOAP-based Web services and the other using RESTful Web services) of a computing system exposed as a Web service is presented.
