Services are expected to be a promising way for people to use information and computing resources in the emerging ubiquitous network society. In this study, we propose a metaphoric concept called flowable service. It is defined as a logical stream that organizes and provides circumjacent services in such a way that they are perceived by individuals as those naturally embedded in their surrounding...
Cloud computing, a new thing which is only three years old, becomes the most fashionable technology and developing trend in IT industry now. People say “X as a service” in the cloud computing, which means that everything including software and hardware can be taken as a service for consumers in the cloud. Meanwhile, a high quality multimedia conferencing has been an urgent requirement these years...
In order to relieve the conflict between improving service quality and enhancing resource efficiency in Web proxy cache cluster, a new elastic Web proxy cache cluster-EWPCC is presented. Basing on the “on demand” characteristic of cloud computing, EWPCC could acquire resource from cloud when the Web cache system is overloaded and release unnecessary cloud resource after load down. In this way, using...
Cloud computing, as an emerging computing model, is drawing much attention from academia and industry. Storage resource, computing resource and network resource are three basic resources in a cloud computing infrastructure. How to utilize these resources efficiently and conveniently is a big challenge for building a good cloud computing infrastructure. This paper presents a service-oriented storage...
To follow the technology advancement and satisfy the needs on the RTI software in the “Cloud computing” age, a scheme of remodeling the traditional RTI software to be with “Platform as a Service (PaaS)” architecture was proposed. Software construction, sub-component functions and the method of interacting based on the remodeled RTI software on the WAN were studied. The focus was scheduling computing...
Cloud Computing is a paradigm in which data, applications or software are accessed over a network. This network of servers is called as “Cloud”. Using a client such as desktops, entertainment centers, tablet computers, notebooks, wall computers, handhelds etc, users can reach into the cloud for resources as they need them. Cloud computing is on-demand access to virtualized IT resources that are housed...
Service-oriented computing, cloud computing, and web services composition mark cornerstones of a paradigm shift in software systems engineering. The general new idea is to use as much as possible services that are made available by others, mostly disseminated via the web. In this paper, we present an abstract model for clouds as federations of services together with a specification of semantics and...
This paper proposes a Diseases Notification System which is designed using a SOA pattern. Disease notification is an import component of the disease control systems. A successful diseases notification system will deliver positive effects for human beings. The proposed system is designed and implemented by use of the Business Process Execution Language for the business process layer and Enterprise...
As an emerging technology and business paradigm, Cloud Computing has taken commercial computing by storm. Cloud computing platforms provide easy access to a company's high-performance computing and storage infrastructure through web services. With cloud computing, the aim is to hide the complexity of IT infrastructure management from its users. At the same time, cloud computing platforms provide massive...
