Load Balancing Techniques Applied in Cloud Data Centers: A Review

Abstract

Load balancing in cloud computing has become an important factor in cloud data centers to ensure proper utilization of resources while preserving the quality of service and meeting service-level agreement of the client applications. The paper presents a literature review on various load balancing techniques that have been applied to the cloud data centers. The techniques involve efficient task to resource mapping during provisioning, or dynamically managing resource allotment for tasks in execution, or optimal utilization of link bandwidth of software-defined networks for data flow. A brief summary of the techniques along with a comparative analysis and advantages and limitations of each have been tabulated. Finally, the paper has been concluded with future scope mentioning the essential points to be taken care of while designing a robust load balancing algorithm for better performance, quality of service and availability.
