CLOUDSIM-ArchitecturePrepared By:-Dr. Amin NezaratPayam e Noor UniversityYazd [email protected] IS CLOUD COMPUTING?Cloud computing is the delivery of computing as a service rather than a product , whereby shared resources, software, and information are provided to users as a utility (like the electricity grid) over a network (typically the Internet).Subscription-based services aim to simulateInfrastructure as a Service (IaaS)Platform as a Service (PaaS)Software as a Service (SaaS)Cloud model described by ownership and paying modelsprivate cloudspublic cloudshybrid clouds

THIS IS THE CLOUDCloud Sim: A Framework For Modelling And Simulation of Cloud Computing Infrastructures And ServicesMain featuressupport for modelling and simulation of large scale Cloud computing data centres.support for modelling and simulation of virtualized server hosts, with customizable policies for provisioning host resources to virtual machinessupport for modelling and simulation of energy-aware computational resourcessupport for modelling and simulation of data centre network topologies and message-passing applicationssupport for modelling and simulation of federated cloudssupport for dynamic insertion of simulation elements, stop and resume of simulationsupport for user-defined policies for allocation of hosts to virtual machines and policies for allocation of host resources to virtual machines

CloudletThis class models the Cloud-based application services









VMThis class models a virtual machine, which is managed and hosted by a Cloud host component.









CloudletScheduler This class is extended by implementation of different policies that determine the share of processing power among Cloudlets in a virtual machine.









HostThis class models a physical resource such as a compute or storage server.









BwProvisioner This is an class that models the policy for provisioning of bandwidth to VMs. Design and Implementation of CloudSim CloudSimNetwork TopologyCloudCoordinator








VmScheduler

This is an class implemented by a Host component that models the policies required for allocating processor cores to VMs.









Ram Provisioner This is an abstract class that represents the provisioning policy for allocating primary memory to the VMs.
