Cloud Computing is the rising field of newest computing in this day and age. The cloud computing is based on the five essential characteristics and its three prime services (Software as a Service, Platform as a Service, Infrastructure as a Service). The major goal of cloud computing is to provide the resources as a services to the cloud consumers or clients. The new concept of Federated Cloud Computing in which multiple datacenters are distributed over different geographical regions. Since the evolution of Cloud Computing: Load balancing and management, energy efficient management, Virtual Machine(VM) migration, service brokerage policies, cost modeling, security issues and trust management are popular research topics in the field. The process of deployment of real cloud environment for testing or for commercial use is extremely costly. Cloud simulators help to model various cloud applications and it is very easy to analyze. In this survey, we used the CloudAnalyst, GUI Java based simulator with their overview are presented so it can be easily decided which one is suitable for particular research topic. And also the survey on the service broker policy, its issues and available solutions are presented. In this thesis we focused on performance evaluation of large data centers using some parameters like cost, service broker policies, User base, Number of physical machines in data centers, Data centers processing time, load balancing policies. Because there is always been the requirement to select appropriate datacenter so that further tasks for processing the request should be carried out with efficiency in least response time. So the issue of selecting appropriate datacenter which is known as service broker policy is kind of important. We also demonstrate the trust as factor majorly used between the cloud service provider and cloud consumers.
