A Various Load Balancing Techniques and Challenges in Cloud Computing : Survey

Cloud computing is a virtualization of cloud program through internet connection, in which there is no need of installing application on everywhere. In cloud computing applications are provided and managed by the cloud provider. Cloud users may access the resources through computer notebook, smart phone or other devices, so they can store data on servers and can access data through Internet. It offers the facility of pay per use to their customers. In cloud computing, clients are demanding more services so for that load balancing of resourcing must be required. Load occurs when the number of job increases. The load can be a memory, CPU capacity, network, or delay load. Load balancing ensures that all the processors in the system do equal amount of work to make the best response time and also good utilization of the resources. Load balancing can be achieved by maximizing throughput or by minimizing response time. In this paper, it describes a survey on load balancing schemes in cloud environment. There are various load balancing techniques used in this paper and their corresponding performance metrics, advantages and disadvantages are studied. These scheduling algorithms focus on response time, make span, execution time and throughput as evaluation parameters.
