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)
Cloud Features & Benefits for Users
Highly virtualized and standardized infrastructures
Massive scalability
Fault tolerant & highly reliable
Intra- & Inter-cloud load balance
Instant application deployment
No need to install or update SW or HW; access from any browser
Unlimited use
Always on
Access from anywhere
Many services to choose from
