CloudSim is a framework for modeling and simulating cloud computing infrastructures and services. It allows modeling of datacenters, virtual machines, hosts, and workloads. Key components include data centers, hosts, virtual machines, brokers, and cloudlets. It supports modeling of policies for resource provisioning and scheduling.

- 2. Simulation Without creating an actual structure we see the results by modeling a dummy structure having same parameters
- 3. Why ? Cloud computing requires a large amount of infrastructure , huge amount of money is required for it. To know the feasibility of cloud for a particular application we simulate it. Many simulaton s/w available …we see Cloud Sim today !!
- 4. Cloud Sim A frame work made on java Simulates cloud services Collection of java classes representing different features of cloud It Models DataCentre, Host, VM, Cloudlets
- 5. Cloud Sim ..Entities.. Components Data Centre Host Virtual Machine Broker Cloudlets
- 7. Data Centre: Represents Complete hardware It has set of hosts(physical machine) Hosts: Physical Machine It has variables to represent memory, processors, id, scheduling scheme etc.
- 8. Virtual Machine(Vm) One host have multiple virtual machines.
- 9. Scheduling There are two main areas to be scheduled: i) Allocation of Processor to VM (Vm Scheduler) ii) Submission of Cloudlet to VM (Cloudlet Scheduler)
