Load Balancing Algorithm for Cloud Computing Using Distributed Data-Centers

Abstract Virtualization techniques, high speed internet access and Service Oriented Architecture (SOA) allow users to access computing resources on pay-as-you-go basis under Cloud environment. The organizations neither need to purchase expensive hardware such as servers, storage, networking equipments etc. nor require skilled manpower for in-house software development. Cloud computing provides scalable and cost-effective solution at a nominal initial investment. Distributed data-centers in Cloud environment run user’s applications with minimum latency by exploiting computing resources geographically near their locations. Load balancing algorithms play important role in equalizing load among datacenters and in efficient use of computing resources. In this paper, performance of a dynamic load balancing algorithm has been evaluated by dividing data-centers in different zones. It has been shown that the proposed algorithm improves the computing efficiency of data-centers and minimizes the response time of user’s applications.
