Abstract

Virtualization plays a vital role in cloud computing. It provides better manageability, availability, optimistic provisioning, scalability and resource utilization in current cloud computing environments. However the performance issue is a major concern in virtualization. The performance of the application running inside the virtual machine gets affected by the interference of the co-virtual machines. This approach provides a novel task scheduling mechanism that allocates the suitable resources to virtual machines which are running in parallel. An interference prediction scheme is proposed to utilize characteristics that are collected when an application running on virtual machines to maintain less system overhead. Nelder-mead method is employed in prediction to create relationship model from the observed response and control variables. A hybrid algorithm: Ant Colony Optimization and Cuckoo search algorithm with K-means++ is adopted for task scheduling process. This approach shows effective improvements in terms of throughput and execution time.

Abstract

Cloud Computing is an emerging paradigm in the advanced network arena that facilitates the users to access shared computing resources through internet-on-demand. Cloud Computing has been widely used since it brings tremendous improvements in business. Cloud users are expected to grow exponentially in the future. In order to meet the demands of future cloud users, a full-fledged survey analyzing the various issues is the need of the hour. The different classifications presently available do not present the issues at micro levels. Amongst the various issues, the ones at design and implementation levels are of utmost importance since they directly affect the performance of the applications. Hence the cloud issues at those levels are presented in this paper from the available literature. This paper also attempts to outline a few possible solutions for some of the issues.

Keywords
