Service gateway for providing a scalable and loosely coupled service oriented architecture

Abstract

The present invention utilizes a service gateway as a communication intermediary between clients and service providers. The gateway can include a dynamic runtime cache. Clients can communicate with the service gateway using a polling methodology. When polled information is already in the cache, the information can be immediately provided to the clients. Otherwise, the information can be obtained by querying a service provider. Service providers can communicate with the gateway using a subscription methodology. Information updates relating to subscriptions can be pushed to the cache. Hence, the cache always contains current information. Thus, clients are able to remain loosely-coupled in a service oriented architecture (SOA) without the SOA suffering from scalability or latency issues, which occur in conventional SOA implementations as the number of clients increase.
