A Robust Algorithm for Capacity Management to Improve Response Time in Virtualized Data Centers

Cloud computing is the use of computing assets or resources (hardware and software) that are consigned as a service over the internet. If cloud computing environment is deployed in a data centre than users can store their data in the cloud centers (i.e. Cloud storage) using storage as a service. When data centre provides storage as a service, the capacity of data centre is biggest challenge. The management required to maintain the capacity at the data centre result in increase of overhead and cost of service on cloud. Therefore to provide scalable and elastic cloud storage to the users or consumers virtualization of data centers is required. In this work, to manage the capacity of these virtual data centers efficiently, it is proposed to do the scheduling of resources over the data centers. The results of the implementation of the proposed methodology not only provides efficient capacity management but also reduces communication overheads and minimize computational cost of the cloud.
