Cloud Computing is the Fifth Generation of Computing (after Mainframe, Personal Computer, Client-Server Computing, and the web)

Estimated size of the cloud computing Infrastructure market in 2012, up from $16B in 2008, IDC October 2008

The cloud is a next generation platform that provides dynamic resource pools, virtualization, and high availability.

• The vocational training on CLOUD COMPUTING included a majority of seminars along with practical exposure to the various cloud servers hosted by the companies like:-

Amazon Google Citrix Cotendo Strangeloop

• • Some of the major topics covered during the training were:

History of Cloud Computing Pros and Cons Deployment Models Virtualization

““The Cloud”The Cloud”

A style of computing where massively scalable (and elastic) IT-related capabilities are provided “as a service” to external customers using Internet technologies.

Acquisition Model: Based on purchasing of services

Business Model: Based on pay for use

Access Model: Over the Internet to ANY device

Technical Model: Scalable, elastic, dynamic, multi-tenant, & sharable

WHY CLOUD

• Cost– Many systems have variable demands

• Batch processing (e.g. New York Times)• Web sites with peaks (e.g. Forbes)• Startups with unknown demand (e.g. the Cash

for Clunkers program)

– Reduce risk• Don't need to buy hardware until you need it

• More than scalability - elasticity!– Ely Lilly in rapidly changing health care business

• Used to take 3 - 4 months to give a department a server cluster, then they would hoard it!

– Using EC2, about 5 minutes!• And they give it back when they are done!

• Scaling back is as important as scaling up

How Cloud Computing Works

• Various providers let you create virtual servers– Set up an account, perhaps just with a credit card

• You create virtual servers ("virtualization")– Choose the OS and software each "instance" will have– It will run on a large server farm located somewhere– You can instantiate more on a few minutes' notice– You can shut down instances in a minute or so

• They send you a bill for what you use

What is Cloud Computing?

1. Web-scale problems2. Large data centers3. Different models of computing4. Highly-interactive Web applications

DIAGRAMETRIC REPRESENTATION

CLOUD LAYERS

The cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns

On-site Community Cloud Scenario Outsourced Community Cloud

The cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services. Examples of Public Cloud:

Google App Engine IBM Smart Cloud Amazon EC2

The cloud infrastructure is a composition of two or more clouds

Examples of Hybrid Cloud:Windows Azure (capable of Hybrid Cloud)VMware vCloud (Hybrid Cloud Services)
