Simulation

Without creating an actual structure we see the

results by modeling a dummy structure having same

parameters

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 !!

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

Cloud Sim ..Entities..

Components

Data Centre

Host

Virtual Machine

Broker

Cloudlets

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.

Virtual Machine(Vm)

One host have multiple virtual machines.

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)
