―CLOUD.....CLOUD .....‖ become the buzzwords for the research field. The cloud has been provided by the service providers like Microsoft, Google, Rackspace, and IBM.

The services given to users can be affected by many issues like security, service level agreement, and multi-level tenancy. This paper gives the review on the load balancing concepts, what are the previous methods to balance the traffic, issues in load balancing and its types. This paper also reviews the various techniques in load balancing cloud environment.
