Due to rapid increase in use of Cloud Computing, moving of more and more applications on cloud and demand of clients for more services and better results, load balancing in Cloud has become a very interesting and important research area. Load Balancing is essential for efficient operations in distributed environments. In cloud computing the load balancing concept broadly classify in three stages as Data Centre Selection, Virtual Machine Scheduling and Task Scheduling at particular data centre. Many algorithms were suggested to provide efficient mechanisms and algorithms for assigning the client’s requests to available Cloud nodes. In this paper, we explained different algorithms and techniques proposed for Virtual Machine Scheduling either at single data centre or multiple data center. Also infers their characteristics to resolve the issue of efficient Virtual Machine Management in Cloud Computing. We discuss and compare these algorithms and techniques in regards of various performance matrices to provide an overview of the latest approaches in the field.
