Research And Implementation Of Cloud And Enterprise Appolication Integration

With cloud computing technology becoming mature, capability and stability of the cloud platform also mature, more and more enterprise applications migrate to the cloud platform. Demand for enterprise integration gradually changes from integration among corporations’internal systems to the integration between cloud services and enterprise applications. However, the existing enterprise integration solutions are only suitable within the enterprises that have stable business and load. Once the need to integrate with cloud services arises, these solutions have to adapt to the features of cloud services, which consist of diversity, scalability, and deploying outside the corporate firewall, etc. In order to realize the integration between cloud services and enterprise applications, this thesis studies and implements the following two aspects of cloud service bus: heterogeneous service access, scalability of application integration. The cloud service bus based on an enterprise service bus is a cloud platform, contributing to realizing the integration of cloud to enterprise applications.Firstly, the thesis discusses the elements to realize the interoperability of heterogeneous services. Eliminating the heterogeneity is the basis of the integration. However, the situation of heterogeneous services in the cloud integration is more complicated than in enterprise internal integration. The thesis explores and analyzes unified interface specifications for the interoperability of heterogeneous service, taking advantage of a lightweight data format and design in an interactive way, realizing the rapid and safe access to heterogeneous services.Secondly, this thesis researches the scalability of integration application which assembles heterogeneous services. Cloud service integration brings issues on the scalability of integrated framework. Traditional enterprise integration solutions, which are not scalable, will inevitably become the bottleneck in the process to cloud integration. Taking the model and operational process of integration application into consideration, this thesis designs a distributed framework and a transferring policy for service instances. In addition, it makes a detailed analysis and comparison of scalable timing and strategies, realizing the dynamic scalability of application integration.Finally, the thesis introduces the prototype system for cloud service bus, and combined with specific scenarios demonstrates the effect of Cloud Service Bus.
