Web has become an open platform where everybody can build and run their applications. Big companies can manage the expenditure themselves. Small company or a single user wants to create web services, better they can rent the computing infrastructure. All the big companies are investing heavily on this Cloud technology. Few notable, important and popular cloud based products are g-mail and yahoo mail...
The creating of reusable mobile solutions is influenced by many factors. The platforms are arbitrary, the target audience can be new to mobile software, and the devices are not always online and restricted in their computational capabilities. This paper presents an archetype pattern- and REST-driven approach for building customizable, flexible, and efficient mobile business applications. Furthermore,...
The following topics are dealt with: service composition; quality of service; cloud services; data management; business process; semantic Web; services systems; services management; service applications; services evolution; ontology; service-oriented system engineering; SOA; services discovery; and Web services.
Paper deals with the design issues of an e-Learning Computational System based on a Task Management Model. One of the main components of the proposed e-Learning Computational Cloud is the Controller acting as an Enterprise Service Bus (ESB) for absolute Model abstraction from outside references. Simultaneously, View is completely decoupled from Model and ultimate privacy and security is achieved for...
Summary form only given. Accountability in Service Oriented Architecture (SOA) is a capability of making business processes across all participants (services, applications and people) accountable in terms of both business logic and Quality of Services (QoS). While accountability is a critical mechanism to enhance trust between collaborative services, there is the lack of standard accountability support...
Business agility is of vital importance to chemical and petroleum industry, especially in rapid response to diagnose and exchange of real-time information and other relevant data sources. From IT perspective, emerging delivery models such as cloud computing offer the possibility to build the elastic infrastructure and flexible computing platform, thus enable enterprises to focus on their core competences...
Industrial adoption of cloud computing for collaborative business processes is limited by their ability to meet inter-enterprise security requirements. Although some clouds offerings comply with security standards, no solution today allows businesses to assess security compliance of applications at the business level and dynamically link to security countermeasures on-demand. In this paper, we present...
Cloud Computing Environments enable business agility and enterprises to exploit/respond quickly to changes in the marketplace, competition, technology and operational environment. For enterprises, CCE present a number of issues and challenges. Some of these include the inability to take advantage of the dynamic resource elasticity of CCE, issues of data fragmentation and duplication, the challenge...
Cloud computing has been a hot topic in the research community since 2007. In cloud computing, the online services are conducted to be pay-as-you-use. Service customers need not be in a long term contract with service providers. Service level agreements (SLAs) are agreements signed between a service provider and another party such as a service consumer, broker agent, or monitoring agent. Because cloud...
Cloud computing promises to increase the velocity with which applications are deployed, increase innovation, and lower costs, all while increasing business agility. Based on the introduction of cloud computing layers and architecture, this paper focuses on discussing how to use cloud computing to design, build, and deliver enterprise applications with Amazon Web Services provided by Amazon. In building,...
IT Service Continuity Management (ITSCM) delivers the recovery of IT services in the event of a disaster. ITSCM is widely perceived as an expensive challenge for enterprise-class IT operations. Cloud computing offers a model for dynamic, scalable infrastructure resource allocation on a pay-per-use basis. These attributes promise to bring cost-efficiency to ITSCM invocation and operation processes...
As the growth of IT spending has trended down to the mid-single digits in recent years, the IT services industry has continued to focus on productivity improvement to take out costs. While innovations in new service business and delivery models are keys to margin growth, service quality is ever more important to protect the client base. This paper reports end-to-end current practices in the enterprise...
More and more companies are outsourcing parts of their business processes to third party providers to exploit the expertise and economies of scale of these third party providers. In the IT field, emerging delivery models for software such as Software as a Service and cloud computing offer the possibility to outsource applications and computing infrastructure and thus enable enterprises to focus on...
Cloud computing is evolving as a key computing platform for sharing resources that include infrastructures, software, applications, and business processes. Virtualization is a core technology for enabling cloud resource sharing. However, most existing cloud computing platforms have not formally adopted the service-oriented architecture (SOA) that would make them more flexible, extensible, and reusable...
BPEL is the de facto standard for business process modeling in today's enterprises and is a promising candidate for the integration of business and Grid applications. Current BPEL implementations do not provide mechanisms to schedule service calls with respect to the load of the target hosts. In this paper, a solution that automatically schedules workflow steps to underutilized hosts and provides...
