The evolution of IT l ed Cloud computing technology emerge as a new prototype in providing the services to its users on re nted basis at any time or place. Considering the flexibility of cloud services, innumerable organizations switched their businesses to the cloud technology by setting up more data centers. Nevertheless, it has become mandatory to provide profitable executi on of tasks and appropriate resource utilization. A few approaches were outlined in literature to enhance performance, job scheduling, storage resources, Q oS and load distribution. Load balancing concept permits data centers to avert over -loading or under-loading in virtual machines that as such is an issue in cloud computing domain. Consequently, it necessitate the researchers to layout and apply a proper l oad balancer for cloud environment. The respective study represents a view of problems and threats f aced by the current load balancing techniques and make the researchers find more efficient algorithms.
