Location transparency offers some significant benefits in the areas of middleware, Service-Oriented Architecture (SOA) and Cloud Computing. However, methods for achieving location transparency in a Web service environment are scarcely presented in the literature. This paper introduces such a method by describing a design and HTTP protocol-based implementation of location transparency. A number of benefits, including support for the creation of a virtual platform and increased mobility, availability and scalability of services, are elaborated. Two significant capabilities -performance-based load balancing and failover -are demonstrated as part of the experimental results.
