As the IT industry is growing day by day, the need of computing and storage is increasing rapidly. The amount of data exchanged over the network is constantly increasing. These services return the required information in form of text, images, video etc. In Cloud computing, Load Balancing is required in such situations to avoid overload. A load balancer technique mediates client access requests to servers and intelligently decides which server is best placed to fulfil each request. Restful interfaces are mainly used for implementation of web services and are based on the resource-oriented approach. This paper discusses the some existing load balancing algorithms in cloud computing. In this review paper, Restful services are used for data storage and retrieval from Cloud system. Cloud is a storage mechanism in which one can store, process data on demand. Load balancing approach is used to distribute load dynamically among the all the nodes in the cloud. Load balancing avoids the occurrence of such a situation where some virtual machines are heavily loaded or in ideal situation. This approach has reduced the amount of data used for recovery to almost half and also maintains a secure access control mechanism for authenticated user.
