An Enhanced R-R Load Balancing Algorithm for VM Scheduling in Cloud Computing Environment

Cloud computing is the next generation of computation and comprises web-based tools and applications as opposed to a direct connection to a server. Cloud providers typically use a "pay-as-you-go" model, which can lead to unexpected operating expenses if administrators are not familiarized with cloud-pricing models. The availability of high-capacity networks, low-cost computers and storage devices as well as the widespread adoption of hardware virtualization, service-oriented architecture, and autonomic and utility computing has led to growth in cloud computing. It is a model that provides an on-demand network access to a shared pool of computing resources. It comprises a huge number of concepts primarily Load Balancing, Scheduling, etc. The number of users in cloud computing is growing in an exponential rate at every day. The number users access cloud server by sending enormous request for many application which lead to high load on cloud server. To reducing the heavy load on server, the virtual machines are allocated for resources based on priority. Allocating the resources on virtual machines based on priority achieves the better response time and processing time. The main aim of the system is to minimize the make span and to maximize the resource utilization and user satisfaction.
