Cloud computing is a recent breakthrough in which infrastructure and IT applications are provided as "services" to end users in a usage-based payment model. You can take advantage of virtualized services even on the fly based on the requirements (workload and QoS patterns) that vary over time. Application services hosted under the Cloud Computing model have complex requirements for provisioning, composition, configuration, and deployment. It is difficult to evaluate the performance of cloud provisioning policies, application workload models, and resource performance models in a repeatable manner under different system and user configurations and requirements. To overcome this challenge, we propose CloudSim: a set of extensible simulation tools that allows modeling and simulation of cloud computing systems and application provisioning environments. The CloudSim toolkit supports both system modeling and behavior of Cloud system components such as data centers, virtual machines (VMs), and resource provisioning policies. It implements generic application procurement techniques that can be extended with ease and limited effort. Currently, it supports the modeling and simulation of cloud computing environments that consist of individual and interconnected clouds (cloud federation).
In addition, it exposes custom interfaces to implement procurement policies and techniques for allocating VMs in cloud computing scenarios across networks. Several researchers from organizations, such as HP Labs in the United States, are using CloudSim in their research into cloud resource provisioning and efficient power management of data center resources. The CloudSim utility is demonstrated by a case study that involves the dynamic provisioning of application services in the hybrid federated cloud environment. The result of this case study demonstrates that the federated cloud computing model significantly improves application QoS requirements under fluctuating patterns of demand for resources and services.
