Cloud computing brings a rapid way for enterprises to launch a new software, which needs lower cost compared with self-purchased infrastructure. More and more enterprises compact their business software as services into cloud platform to the users. In service auction, the service provider aims to make more profits from the service it provides, but the service consumer hopes to select a good quality...
One of the obvious challenges in cloud environments is trust crisis and its influence on the development of cloud computing. This paper analyzes the similarities and differences between cloud computing and other distributed environments, proposes the concept of trust and three different directions of trust-oriented research in cloud environments. According to three directions of trust-oriented research,...
While most of work on task-resource matching in centreless network has focus on evaluating multi-QoS constraints in quantity, our work addresses this problem from types of QoS constraints, objectivity of matching process, and concurrency of multiple matches. An algorithm of matching resources for multi-tasks synchronously, MRMT, is presented. Firstly, an improved analytic hierarchy process (AHP) method...
To improve the performance of center-less network, appropriate strategies and algorithms of task-resource matching are of importance. Some of QoS guided algorithms based on Min-Min have been investigated while flexibility and multi-QoS constraints of them need to be further researched. Firstly, task-resource matching methods in center-less network are reviewed. Secondly, a multi-QoS constrained task-resource...
While most of the work on resource scheduling in Grid computing has focused on optimal make span of the whole systems, our work addresses this problem from the resource consumer's point of view by providing multi QoS constraints and related methods. An algorithm of resource evaluation and selection, RESA, is presented, applying multiple attribute decision making (MADM) and hierarchical analysis methods...
