Web Services Platform Architecture Machine and SOA Model Design

Service-oriented new software system development has gradually been proposed and gets rapid development with the emergence of Web services.Service oriented architecture (SOA) makes changes in creation and development of deployment application system, and will become the effective way to solve enterprise complex IT environment.This paper expounds the basic concepts of SOA, system structure, basic characteristics and relationship between SOA and Web Service technology, and probes into SOA system application architecture design based on Web Service.In recent years, SOA, service-oriented software architecture, a software engineering method rises gradually.It provides an effective way to solve SOA scattered business and the application of crossplatform.It has characteristics like coarse-grain, loosely coupled, standard structure, and shared services, etc.But at the moment, in terms of Web Service's SOA structure design, there is still lack of in-depth research.This paper explores the basic concept, system structure, basic features of SOA and the relationship between SOA and Web Service technology, and studies SOA system application architecture design based on Web services platform architecture. I. SOA AND WEB SERVICE TECHNOLOGYA. The basic concepts of SOA SOA, on the thought of software becoming services, puts forward new software integration and solutions of software reuse.SOA model can be more suitable for large-scale application scenario like across enterprise electronic commerce system or a cross-department e-government system and so on.Service-oriented software architecture is a component model.It contacts contract through well-defined interfaces between services.SOA uses a neutral way to define interfaces.This defining with neutral excuse characteristic is known as loose coupling between services.Loose coupling system not only has good flexibility, but also is able to exist in each service internal structures' gradual changes for the application composition.SOA is an alternative model for object-oriented model.Compared with the previous object model and component model, service-oriented architecture (SOA) pays more attention to "business as the center" service entity, rather than "technology as the center" fine-grained entity.It seems that SOA is coarse-grained, loosely coupled services architecture, and it does not involve the underlying programming interface and communication model between services.It communicates only through simple and accurate definition interfaces.SOA can help enterprise system architectures more rapid and reliable entire business system, and can also help software engineer stand in a whole new level to understand various forms development of the enterprise architecture.In SOA, service is one of the critical concepts.Developers can understand the data from one or more data changes to obtain data.SOA organization is different from single application.It forms its own applications through direct services building by developers.SOA has a huge advantage, and is a kind of new solution for Web application system building.By analyzing the interaction between services, make the analysts and administrators optimize business process specifically.B. SOA architecture Service users, service provider and service registry center are the three roles in SOA architecture, as shown in Figure 1.Service providers pack available information or business process as a service, and then release them into the registry.Service registry will classify service issued by the service 4th National Conference on Electrical, Electronics and Computer Engineering (NCEECE 2015)
