There is an emergence of Cloud application platforms such as Microsoft's Azure, Google's App Engine and Amazon's EC2/SimpleDB/S3. Startups and Enterprise alike, lured by the promise of `infinite scalability', `ease of development', `low infrastructure setup cost' are increasingly using these Cloud service building blocks to develop and deploy their web based applications. However, the precise nature...
Web services composition technology is promising technology to efficiently integrate heterogeneous, distributed and legacy software system. Performance becomes the key issue when Web services composition model complex and mission-critical application. The defect of design can result in the performance bottleneck problem in the running time. In this paper, we propose a simulation-based model for the...
In recently years, Web service composition becomes a new approach to overcome many difficult problems confronted by B2B e-commerce, inter-organization workflow management, enterprise application integration etc. Due to the uncertainty of the Internet and various Web services, the performance of the composed Web service can not be ensured. How to model and predict the performance of the composed Web...
Web Services can be composed to build domain-specific application and solution. Some Web Services Composition (WSC) standards are proposed, for instance, WS-BPEL and WS-CDL. WS-BPEL consists of basic activity, structured activity and control-flow. It uses control-flow to construct sequence, branching, parallelism, synchronization, etc. This paper proposes an approach to formally analyze transaction...
Web services can be composed to build domain-specific application and solution. The standards of several Web services composition (WSC) are proposed, for example, WS-BPEL and WS-CDL. Moreover, there is a great demand for the performance optimization of WSC recently. However, WS-BPEL lacks formal semantics, so it is very difficult to verify WSC and evaluate the performance of WSC. Therefore, considering...
With the development of information service, tourism e-commerce is facing more challenges. Through a profound analysis of Chinese current tourism e-commerce, the paper puts forward a tourism e-commerce model based on web service, and probes the application of this model, which realizes information services in Chinese tourism industry.
The existing modeling methods for Web service composition are not suitable for modeling Web service composition on the business layer. A novel concept model, called DWSCCM, for Web service composition on the business layer are represented in this paper. The initial experiments based on DWSCCM model show that this model is feasible and efficient.
Many new-style medical treatment systems have been developed. Due to employing various incompatible methods respectively, the most of existing medical systems lack abilities to collaborate with each other. To break the technical barriers and build an open and collaborative medical treatment system, a distributed model, named DM4MTS is represented in this paper. Combining multiple techniques, such...
