Dynamic scaling of web services for xen based virtual cloud environment

Abstract

According to its supporters, cloud computing is emerging as a fast-growing technology that is gauged to succeed where other attempts to deliver hands-on computing to general public with a network connection have failed. One of the essential benefits of using cloud computing is the feature of scalability. In this paper, keeping in mind the `scalability' factor of the Cloud, a system is proposed that dynamically scales the web services in a virtualised cloud computing environment consisting of a front end load balancer that balances the load of the incoming HTTP requests, a Cluster Monitoring System that constantly fetches the information of the current states of the Virtual Machines and an auto-provisioning system that runs a novel algorithm in the back-end according to which virtual machines are scaled.
