GREEN CLOUD COMPUTING- A PROGRESS TOWARDS
ENVIRONMENT SUSTAINABILITY
SUBMITTED BY:-SYED JAUWAD
The World of Interneto As the number of internet
users is growing exponentially the need of cloud computing came into existence.
o This overcomes the limitation of the amount of information present on a single server by allowing the user to link to any remote server for information.
o Cloud computing is providing utility
based services to all the users
worldwide.
o Data centers created for cloud
computing applications consume huge
amounts of energy, contributing to high
operational costs and a large amount of
carbon dioxide emission to the
environment.
o It leads to an abrupt level of power
consumption and increasing the amount
of harmful gases in environment.
Why think for green cloud computing??
Our Concern……….
We need green cloud computing solutions that can not only save energy, but also reduce operational costs and enrich environment sustainability.

What constitutes Green Cloud computing?
1. Cloud Computingo A cloud is a distributed
computing system consisting of a collection of interconnected and virtualized computers .
o Cloud is dynamically provisioned and presented as unified computing resources based on service level agreements established through negotiation between the service provider and consumers.
Software as a Service
(SaaS)
Platform as a service
(PaaS)
Infrastructure as a
Service (IaaS)
Types of cloud computing
i) Software as a Service (SaaS):o Topmost layer of cloud computing architecture, which is a software delivery
model providing on-demand access to application.o Referred to as “On demand software” and is usually priced on a pay per use
basis.ii) Platform as a service (PaaS):o Facilitates the deployment of application without the cost of buying managing
the hardware and software and provisioning the hosting capabilities.o It may also include facilities for application design, application development,
testing and deployment.
iii) Infrastructure as a Service (IaaS):o Presents computers as virtual machines and offers additional resources such
as images in a virtual machine image library, block and file based storage, firewalls, load balancers and IP addresses.

2. Green Computingo Green computing is the study and
practice of environmentally sustainable computing or Information Technology.
o The green computing can be achieved by reducing the overall power consumption.
o This can be accomplished by redesigning the infrastructure of network by reducing the number of servers, switches and cables or by applying the different power consumption schemes and patterns.
o The concept of Green cloud computing has come after the addition of the advantage of green computing with the cloud computing.
o The green cloud presents a simulation environment for energy aware cloud computing data centers.
3. Green Cloud Computing
Core component of Green cloud computing …..
o Data Center :
Data center is a subdivision of information and communication technology service provider organization where this organization can operate most of the ICT infrastructure that supports to their clients.
the network system devices used in creating data centers are switches, links and servers.
Three tier high speed Data center architecture
Data center architecture
The architecture typically includes three layers:o Access layerSupports the loop-free topology due to the inexpensive Layer-2 (L2) switches in
the access layer.o Aggregation layerIncrease the number of server nodes to more than 10,000 servers but it leads to
the increase in the cost due to increase in number of servers.o Core layerA typical three tier architecture includes eight core switches). An 8-way ECMP
includes 10 GE (Gigabyte Ethernet) Line Aggregation Groups (LAGs) which permit a client to access several links and network ports with a single MAC address.
Devices that make a Data Center…
o L3 switches o Server rackso 10 GE (Gigabyte
Ethernet) Line o Layer-2 (L2) switches o 100 GE links
Annual Number of Google Searches in
2012 is 1,873,910,000,000 as
per the official web blog of Google.
One Google search releases about 0.2
grams of CO2.
It means 1026 tones greenhouse gas
emissions per day by Google.
Several recent studies and articles show that most computers create
40-80 grams of greenhouse gas
emissions per hour through their
electricity use.
Analysis and findings for existing systems
( Green Cloud Simulator)
The key to the success of energy efficient clouds is “Virtualization”.
Green Cloud Simulator….
o Green cloud simulator provides the modeling environment for describing energy consumed by the elements of the data center such as server, switches and links.
o The main focus of green cloud simulator is on the packet level simulation of communication in the data center infrastructure which provides the finest control and distinguishes it from any other cloud simulation environment.
o The baseline of Green cloud simulator is derived from NS-2 network simulator. It comes as a pre-confined virtual machine (VM) which works with VMWare player.
Green Cloud Simulator….
o The baseline of Green cloud is derived from NS-2 network simulator.
o It comes as a pre-confined virtual machine (VM) which works with VMWare player.
o This VM contains:1. A default Ubuntu 12.04 Desktop 32-bit
installation, with many extra packages removed.2. Use of Languages like TCL, TK, OTCL and TclCL to
be built from source.3. NS2 and Green Cloud simulator is installed from
source by merging process.4. It also includes Eclipse IDE with the NS2/Green
Cloud project already set up.
We try building a new data center in order to describe the total power consumption by several devices of data center.
Objective:
The steps are:1. Install VMPLayer which provides Ubuntu working environment
on windows operating system.2. Open Eclipse IDE which is integrated with a default NS2/Green
Cloud project set up. The source code is displayed in tool command language(TCL).
3. The source code consist of numerical values representing the number of servers, each type of switches and total number of users. To create a new data center, make changes in the numerical values applicable with the formulas.
4. Run the green cloud simulator to perform the calculation on the values and for displaying the progress. It calculates the total energy consumption by each of the device used in data center.
5. The statistical result is displayed on the default browser (i.e. Mozilla Firefox). The output is presented in the form of pie chart and various graphs.
The principle limitation is the high cost of purchase of components that are required to make the cloud computing more efficient (like cooling equipment, carbon emission rating meter, etc.).The high efficiency illustrated by the simulator is very difficult to implement in reality.
The maintenance of the devices included in data center is also a prime limitation.
Limitations of Green Cloud Computing
Future Scopeo For enabling green cloud data
centers, we will understand and analyze the existing data center power and cooling designs, power consumption by the servers and their cooling requirements to achieve maximum efficiency.
o We will also require modeling tools to measure the energy usage of all the components and services of cloud.
For designing the holistic solutions we will consider such as number of servers, each type of switches, number of users and total links in a data center to minimize the overall power usage of a data center.Our main aim will be improving the efficiency of the equipment used in the cloud computing.
