Computing is being transformed to a model consisting of services that are commoditised and delivered in a manner similar to utilities such as water, electricity, gas, and telephony. In such a model, users access services based on their requirements without regard to where the services are hosted. Several computing paradigms have promised to deliver this utility computing vision and they include Grid...
Along with the development of grid computing and cloud computing, finite computing resources supplied by standalone server usually become the bottleneck in the process of system implementation of online trading platform. Moreover, It is difficult to reuse algorithm module and the system also becomes more complicated to achieve. Traditional online trading framework can not preferably solve the problem...
In this paper, we investigate how Service Level Agreeements (SLAs) can be incorporated as part of the system's scheduling and rental decisions to satisfy the different performance promises of high performance computing (HPC) applications. Such SLAs are contracts which specify a set of application-driven requirements such as the estimated total load, contract duration, total utility value and the estimated...
Cloud computing, possibly the most significant new technique in the 21st century, is now bringing enormous impact to the society, especially the business world. It provides services that set clients free from worrying about data processing problems so that they can focus on their major businesses. In this article, characteristics of it will be discussed with several examples, in order to show that...
This paper explores autonomic approaches for optimizing provisioning for heterogeneous workloads on enterprise grids and clouds. Specifically, this paper presents a decentralized, robust online clustering approach that addresses the distributed nature of these environments, and can be used to detect patterns and trends, and use this information to optimize provisioning of virtual (VM) resources. It...
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...
