1.The World of Internet• As the number of internet users is

growing exponentially the need of cloud computing came into existence.

• 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.

2.History of Cloud Computing

• The foundation of the idea of cloud computing began in 1960s. 

• John McCarthy introduced the cloud computing along with few applications.

6GREEN CLOUD COMPUTING

3.What is Cloud Computing?

• A cloud is a distributed computing system consisting of a collection of interconnected and virtualized computers .

• Cloud is dynamically provisioned and presented as unified computing resources based on service level agreements established between the service provider and consume.

i.Software as a Service(SaaS)

Software as a Service (SaaS) is a software distribution model in which applications are hosted by a vendor or service provider and made available to customers over a network, typically the Internet.

GREEN CLOUD COMPUTING

ii.Platform as a Service(PaaS)

• Platform as a service (PaaS) is a cloud computing model that delivers applications over the Internet.

• In a PaaS model, a cloud provider delivers hardware and software tools -- usually those needed for application development -- to its users as a service.

• As a result, PaaS frees users from having to install in-house hardware and software to develop or run a new application.  

10GREEN CLOUD COMPUTING

iii.Infrastructure as a Service(IaaS)

• Infrastructure as a Service (IaaS) is a form of cloud computing that provides virtualized computing resources over the Internet.  IaaS is one of three main categories of cloud computing services, alongside Software as a Service (SaaS), Platform as a Service (PaaS).

7.What is Green Computing?

• Green computing is the study and practice of environmentally sustainable computing or Information Technology.

• The green computing can be achieved by reducing the overall power consumption.

• 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. 14GREEN CLOUD COMPUTING

8.What is Green Cloud Computing?

• The concept of Green cloud computing has come after the addition of the advantage of green computing with the cloud computing.

• The green cloud presents a simulation environment for energy aware cloud computing data centers.

9.Core component of Green cloud computing

…..• Data CenterDD

Data centers:

• 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.

GREEN CLOUD COMPUTING

10.Data center architecture

17GREEN CLOUD COMPUTING

11.The architecture typically includes three

layers:• Access layer Supports the loop-free topology due to the inexpensive Layer-

2 (L2) switches in the access layer.• Aggregation layer Increase 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.

• Core layer A 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.

18GREEN CLOUD COMPUTING

12.Devices that make a Data Center…

•L3 switches •Server racks•10 GE (Gigabyte Ethernet) Line

•Layer-2 (L2) switches

• 100 GE links

19GREEN CLOUD COMPUTING

13.Analysis of Existing system

• 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.

14.Power consumption by various sites…….

21GREEN CLOUD COMPUTING

15. A Solution……

• The key to the success of energy efficient clouds is “Virtualization”.

( Green Cloud Simulator)

22GREEN CLOUD COMPUTING

16.Green Cloud Simulator….• Green cloud simulator provides the

modeling environment for describing energy consumed by the elements of the data center such as server, switches and links.

• 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.

• 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.

17.Contents of VMWare Player

• A default Ubuntu 12.04 Desktop 32-bit installation, with many extra packages removed.

• Use of Languages like TCL, TK, OTCL and TclCL to be built from source.

• NS2 and Green Cloud simulator is installed from source by merging process.

• It also includes Eclipse IDE with the NS2/Green Cloud project already set up.

24GREEN CLOUD COMPUTING

18.Objective:• The main objective is to build a new

data centre which consumes less amount of energy and releases less harmful gases into the environment.

• It is possible only when we are able to know and calculate the amount of energy consumed now in the existing system.

• It is calculated using VMWare player.

25GREEN CLOUD COMPUTING

19.Steps for calculating the values using VMWare

are: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.

Data center

25.Conclusion • Considering the above statistical values , we

need to regulate the devices , switches, cables that are utilized in a data center , such that the energy consumption becomes less and the amount of harmful gases that are released by the data centers must be reduced.

33GREEN CLOUD COMPUTING

26.Limitations of Green Cloud Computing

• 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 maintenance of the devices included in data center is also a prime limitation.

• The high efficiency illustrated by the simulator is very difficult to implement in reality.

34GREEN CLOUD COMPUTING

27.Future Scope

• 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.

• We will also require modeling tools to measure the energy usage of all the components and services of cloud.

35GREEN CLOUD COMPUTING

28.Continuation….• 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. 36GREEN CLOUD COMPUTING
