The internet is marvelous technology of the computing world. The most exhaustive technology that internet dispense, is the Cloud Computing. It provides instrumental values to the customers and cloud service providers. With the advent of cloud computing the client uses the resources like hardware, software or storage, that are offered by other organization, instead of buying their own resources. However, these cloud services are provided by the cloud service providers by means of virtual machines. This study proposed the various aspects related to cloud computing technology. This paper includes the service model that reveals the various cloud services provides to different types of clients according to their requirements. This study provides the details of the layers in the architecture of cloud computing. Moreover, this study also includes the information about the various types of clouds.

Internet is a great marvel of science. Internet has changed the face of world. It is most essential and revolutionary creation in this world. Cloud computing is associated with internet computing. Cloud computing has undoubtedly benefited both service provider and clients in great extent .There is rapid increase in cloud's customers constantly. Although, the cloud data centers comprised of tremendous power but due to expeditious requests of users there is sudden need of balancing load .However, load balancing emerged as the conspicuous issue in the cloud heterogeneous environment. This study highlights the performance analysis of load balancing policies which are taken in a combination with service broker policy . In Fact, this study addresses that there can be reduction in response time and data center request processing time by using efficient load balancing policies. These all evaluations and results are carried out using cloud analyst simulation tool.

This is age of internet. There is hardly any domain where internet do not play significant role. Cloud Computing relates to internet computing that has revolutionized the whole world. Cloud Computing has undeniably benefited the users in many ways. Load Balancing is emerging as the hottest issue in cloud environment at present. Load due to client requests must be balanced by resources of service provider. In this study we proposed a theoretical framework which is combination of load balancing policy and service broker policy for cloud environment. This paper includes the comparison of the results of proposed algorithm with existing algorithm .This study accomplish that there is extreme reduction in response time at client part and reduction in datacenter request servicing time and resources of resource providers are managed efficiently and effectively by using the proposed algorithm. Several parameters are also identified and these are utilized to compare the traditional round robin load balancing policy with proposed load balancing strategy by using cloud analyst tool as simulator.
