The negotiation on Service Level Agreement (SLA) in current complex cloud environment often involves the multilateral negotiation. Therefore, this paper presents an SLA-oriented multiparty trust negotiation model based on Hierarchical Colored Petri Net (HCPN) in cloud environment. This model mainly provides trust negotiation of SLA parameters such as credibility, reliability, availability and s...

Cloud computing is a revolutionary concept that has brought a paradigm shift in the IT world. This has made it possible to manage and run businesses without even setting up an IT infrastructure. It offers multifold benefits to the users moving to a cloud, while posing unknown security and privacy issues. User authentication is one such growing concern and is greatly needed in order to ensure pr...

Task scheduling in cloud environment is a key technical problem on how to allocate available cloud resources to cloud users. Usually, a task in cloud environment can be cut into a serials of subtasks, which have precedence and dependency relationships among themselves. We describe the problem by means of a DAG (Directed Acyclic Graph) model. Then, we propose a priority algorithm for DAG task sc...

Bridging the gap between design and implementation stages has been a major concern of designers, analysts and developers of information systems and a major aspiration of a number of Information System (IS) engineering approaches. Cloud computing exacerbates the strain on traditional IS engineering approaches that service-oriented computing has started. At the same time, recent research has argu...

In this paper, thinking over characteristics of ant colony optimization Algorithm, taking into account the characteristics of cloud computing, combined with clonal selection algorithm (CSA) global optimum advantage of the convergence of the clonal selection algorithm (CSA) into every ACO iteration, speeding up the convergence rate, and the introduction of reverse mutation strategy, ant colony o...

Cloud computing is an upcoming efficient networking computing environment. Our work proposes sharing an application across various clients of a host system via cloud computing. The sharing is performed between the host storage system and the remote storage system in a cloud computing environment. The Host storage device of the host system is updated to retrieve the application from the remote s...

Cloud computing is emerging technology in today’s era. Its popularity is because of flexibility, scalability, cost reduction and on-demand service. But there is the demand of security in User-Cloud environment, because of dependency increases on the cloud. Several companies chooses cloud environment for business prospective. So when we choose cloud environment we must think about the security i...

Cloud technology in a multi-enterprise, collaborative context is one of the most promising topics at IT-Supply Chain (SC) intersection. Cloud comes with well-proven advantages and cost savings; enabling collaboration and business intelligence. Cloud transition is still on-going with individual enterprise-level transitions. However, collaborative paradigm dictates that entire network well-being ...

The Cloud is an internet-based computing where shared resources, software and information are provided to the computer. Now a days it is one of the prominent technologies to provide wide variety of services. In this condition data can be categorized into sensitive and insensitive. Among these two types sensitive data requires security. The existing system does not provide any security concerns ...

Based on integrated infrastructure of resource sharing and computing in distributed environment, cloud computing involves the provision of dynamically scalable and provides virtualized resources as services over the Internet. These applications also bring a large scale heterogeneous and distributed information which pose a great challenge in terms of the semantic ambiguity. It is critical for a...
