Effective Load Balancing in Cloud Computing

Abstract

Internet, from its beginning so far, has undergone a lot of changes which some of them has changed human's lifestyle in recent decades. One of the latest changes in the functionality of the Internet has been the introduction of Cloud Computing. Cloud Computing is a new internet service, which involves virtualization, distributed computing, networking, software etc. This technology is becoming popular to provide various services to users. Naturally, any changes and new concepts in the world of technology have its own problems and complexities. Using Cloud Computing is no exception and has many challenges facing the authorities in this area such as load balancing, security, reliability, ownership, data backup and data portability. Load balancing is one of the essential factors to enhance the working performance of the Cloud service provider by shifting of workload among the processors. Proper load balancing aids in minimizing resource consumption, implementing fail-over, enabling scalability, avoiding bottlenecks and over-provisioning etc. Given the importance of the process of load balancing in Cloud Computing, the aim of this paper is to review the process and to compare techniques in this field.
