Cloud computing has become a major force for change in how web design, configure, provision, and manage IT infrastructure. Instead of custom-provisioning individual systems or clusters, an architect or administrator is expected to have hundreds, or even thousands of resources under their control! A variety of approaches have emerged to do this. CloudSim enables seamless modeling, simulation, and experimentation of emerging Cloud computing infrastructures and application services. In the CloudSim simulator there are two fundamental problems: i) Lack of links between Datacenters, this lack of links will lead necessarily to a lack of communication between them and therefore no exchange or shared of any service or information with other datacenters. ii) No possibility to create a virtual machine in more Datacenters. In a first time, we propose to use a ring topology to allow the exchange and the and sharing of information and services between different Datacenter, and in the second time improving the method of creating virtual machines, and by consequence to allow the creation of a virtual machine in several Datacenter, which improves fault tolerance in this type of environment.
