Platform as a Service is the major productivity enabler in the cloud computing stack. By providing managed and highly automated application environments, it enhances developer productivity and reduces developer operations and maintenance efforts. The market, however, is fast-changing and offerings are differing conceptually as well as in their supported technological ecosystem. Therefore, provider...
Heterogeneous data and various system that manage data in organization can be one of the difficult factor to manage data and application. SOA proposed several years ago boast an open standard based on loosely coupled architecture for better integrating application in distributed and heterogeneous environment. ESB is introduced as infrastructure for SOA service connection and message exchange that...
Complex application deployment and management over multiple heterogeneous PaaS platform is one of the key problems that have emerged with the cloud technology revolution. Presently, vendor lock-in has become a major PaaS technology challenge. Multi-Cloud PaaS Architecture (MCPA) has been recently proposed research project, intended to resolve complexity and interoperability challenges. MCPA offers...
Cloud Federation offers Cloud Service Providers (CSPs) the ability to lease excess capacity to other CSPs in need of temporary additional resources such as large amounts of computational and networking power, or storage capacity to meet consumer's insatiable demand requirements. This promise, not only directly contradicts the Cloud Computing principles of scalability and elasticity, but also challenges...
Cloud standards are uniquely suited to crossing boundaries that occur in hybrid cloud deployments. This column presents several new efforts in this area and discusses their history and current state, along with related software projects.
The energy consumption of Cloud computing continues to be an area of significant concern as data center growth continues to increase. This paper reports on an energy efficient interoperable Cloud architecture realized as a Cloud toolbox that focuses on reducing the energy consumption of Cloud applications holistically across all deployments models. The architecture supports energy efficiency at service...
Cloud computing (the delivery of computing as services rather than products) creates new challenges with respect to openness. Existing approaches such as open source licensing of software products have proven inadequate in a service-oriented world; attempts to address the limitations by closing the “service provider loophole” have failed to gain traction. Similarly, multiple providers are yet to fully...
Cloud computing has the potential to revolutionize the way systems are developed and marketed. The cloud has become an important research subject in software engineering nowadays. Among the many research gaps related to this new computing model is the lack of portability between cloud platforms, which generates the Data Lock-In. The Data Lock-In is the difficulty in migrating data and applications...
In order to realize the sharing of medical information, coordination of medical, as well as the efficient and cost-effective health information system through the construction of a distributed and high-integrated platform, the medical and health information system infrastructure based on the cloud computing is proposed. And three kinds of application mode, SaaS, PaaS and IaaS, are applied in this...
