GreenCloud is an open source cloud computing simulator that allows researchers to observe and measure cloud performance. It is an extension of the NS2 network simulator and focuses on simulating communications within a cloud at the packet level. The tutorial discusses installing GreenCloud in Ubuntu either through a preconfigured virtual machine, or by manually downloading and compiling the source code. It also provides an example of running a sample simulation script.

Motivation
• The lack of detailed simulators on the market
was the motivation to develop GreenCloud that
allows researchers to observe, interact and
measure cloud performance.measure cloud performance.
GreenCloud is a sophisticated open source
cloud computing simulator
Greencloud as been elaborated in the context
of the GreenIT project.

4. There also was no provisioning for observing
clouds for their energy-efficiency
Simulation environment for energy-aware
cloud computing data centers.
GreenCloud FeatureGreenCloud Feature
GreenCloud is an extension of the well-
known NS2 network simulator
Focused primarily on the communications
within a cloud, i.e., all of the communication
processes are simulated on packet level.

9. We need to download the virtual machine
(Ubuntu) with GreenCloud simulator and
VM contains:
• default Ubuntu installation, with many extraneous
packages removed
Simple way to install GreenCloudSimple way to install GreenCloud
packages removed
• TCL, TK, OTCL, TclCL packages are installed
• NS2 and GreenCloud installed from source
• Eclipse with the NS2/GreenCloud project already set
up
• Only need the VMware Player or VMware
Workstation
VM Download Link : http://greencloud.gforge.uni.lu/vm.html

10. VMware Player 4 is a free software
To download VMware Player :
http://www.vmware.com/go/downloadplayer/
Download and install VMware player according to
the instruction on the screen
Simple way: Run SimulationSimple way: Run Simulation
the instruction on the screen
Extract ubuntu-greencloud-v1.02.tar.gz
Start VMware player from menu select open and
select your ubuntu-greencloud-v1.02 extracted
Power on ubuntu-GreenCloud

13. For example you’ve installed ubuntu 11.10 in
your machine.
Now you want to install GreenCloud in your
machine to simulate cloud.
