Most of the nowadays popular web applications are enriched with AJAX techniques that offer a better experience than classical applications. However, these techniques greatly impact the server’s performance because of their complex features. Regardless their complexity, web applications should ensure the achievement of the imposed performance target even in the presence of workload variations or...
This document defines a framework for certificate management interactions between an Internet Number Resource issuer ("issuer") and an Internet Number Resource recipient ("subject") through the specification of a protocol for interaction between the two parties. The protocol supports the transmission of requests from the subject, and corresponding responses from the issuer encompassing the acti...
To attain the desired reliability and energy efficiency of a cloud data center, trade-offs should be carried out between system performance and power consumption. Although the deployment of energy-efficient hardware is a crucial step, getting rid of underutilized servers is a far more effective approach. Achieving this in a cloud data center would require monitoring resource utilization as well...
Today’s information technology departments have widely varying demands for resources due to unexpected surges in subscriber demands (e.g., a large response to a product promotion). Further complicating matters is that many resource actions done in response to surges (e.g., provisioning or de-provisioning an application server) have substantial delays (lead times) between initiating the resource...
Internet service utilities host multiple server applications on a shared server cluster. A key challenge for these systems is to provision shared resources on demand to meet service quality targets at least cost. This paper presents a new approach to utility resource management focusing on coordinated provisioning of memory and storage resources. Our approach is model-based: it incorporates int...
A fundamental problem in building large scale Grid resource sharing system is the need for efficient and scalable techniques for discovery and provisioning of resources for delivering expected Quality of Service (QoS) to users’ applications. The current approaches to Grid resource sharing based on resource brokers are non-coordinated since these brokers make scheduling related decisions indepen...
The rapid growth of IP-based packet switched network and the overall bandwidth efficiency of an integrated IP network make it an attractive candidate to transport real time voice connections. However, high quality voice over IP (VoIP) remains a challenge because interactive voice imposes many performance requirements (such as loss rate and latency) on the transport network. This cannot be easil...
Cloud computing is an amazing technology, which provides services to users on-demand. Since there are many providers in the cloud, users get confused in selecting the optimal cloud service provider. To overcome this limitation, federated cloud management architecture was proposed. There is no standard framework for ranking the cloud service providers in the existing federated cloud model. The p...
Grid computing is an accumulation of heterogeneous, dynamic resources from multiple administrative areas which are geographically distributed that can be utilized to reach a mutual end. Development of resource provisioning-based scheduling in large-scale distributed environments like grid computing brings in new requirement challenges that are not being believed in traditional distributed compu...
Businesses selling multimedia rich software or e-content are growing in the Internet. The e-content can be downloaded or streamed immediately after an on-line transaction. Since Internet connection speeds are variable, ranging from dial-up access speeds to broadband speeds, a content provider may provide content at different speeds or levels-of-service. Providers offering content at different s...
