Research on Distributed Architecture Based on SOA

In essence, Service Oriented Architecture (SOA) is distributed and shall not have any centralized control point. Any application can access an SOA network for interaction as long as it complies with the corresponding standards. A centralized SOA architecture can also be regarded as a part of SOA. This paper gives a general overview of the fundamental principles, features, and core technologies of distributed SOA, analyzes the integration of distributed object technologies and Web technology, and describes the difference between distributed SOA and centralized SOA. With the previous as a basis, this paper discusses the function and implementation of SOA in the distributed architecture, proposes an SOA-based distributed multi-layer architecture and an application integration frame realized via J2EE. This application integration frame can connect any distributed application without restriction and support data and function sharing among applications,thus simplifying the implementation of the functions at various layers and providing better maintainability and scalability.
