A comparative study on Load-balancing Algorithms for Cloud Environments

Today, demand of distributed computing technique has grown drastically where cloud computing also has gain considerable attention from researchers and industries for various applications. Cloud computing is provided by cloud service provides where various virtual machines are deployed to accomplish the assigned task. During cloud deployment, cloud service providers aim on the energy cost reduction, load-balancing and efficiently accomplishment of the task. Several researches have been carried out to improve the performance of cloud computing but still there arc various issues are unaddressed such as load-balancing, resource allocation, VM migration and energy efficient task scheduling etc. In this article, we have reviewed recent techniques of load-balancing, and resource allocation and discussed about their advantages and drawbacks. A future work plan is also focused for energy efficient load balancing techniques by which performance of cloud computing is enhanced.
