This document provides an overview of cloud computing including definitions, service types, deployment patterns, market drivers and pros and cons. It defines cloud computing as a pay-as-you-go model where consumers pay only for what they use. The main service types are SaaS, PaaS and IaaS. Common deployment patterns are public, private and hybrid clouds. Key market drivers include cost reduction and scalability while disadvantages include availability issues and data ownership concerns.

What is cloud computing?
Cloud Computing is ……..
“An approach to consume technology in a pay-as-you-go
model where consumers only pay for what they use.”

Layers

6. Software as a service(Saas):-
Software deployed as a hosted service accessed over the
internet
Features:-
•Open,Flexible
•Easy to upgrade
•Easy to deploy
•Easy to use

7. Platform as a service:-
Platform providing all the facilities necessary to the
complete process of building and delivering web
applications and service, all available over the Internet.
Entirely virtualized platform that includes one or more
servers,operating systems and specific applications
Features:-
•Database management system
•Server Software
•Support
•Storage

8. Infrastructure-as-a-Service(Iaas):-
Infrastructure as a service delivers basic storage and
Compute capabilities as standardized services over the
network.
Server ,storage system,switche,router and other system
are Pooled and made available to handel workloads the
range from application components to high-performance
computing Applications.
Features:-
• The service provider owns the equipment and is
responsible for housing,running and maintaining it.
• The client typically pays on a per-use basis.

9. Patterns For Cloud Computing:-

10. Public Cloud:-
•A single or combination of SaaS,IaaS,PaaS offerings
shall be shared between multiple companies to reduce
costs and enable a dynamic resource usage following a
pay-per-use pricing model.
•Additional security mechanisms are implemented to
isolate customers from each other.

11. Private Cloud:-
•A single or combination of SaaS,IaaS,PaaS
offerings shall be used internally of a company
since privacy requirements or restrictions by law
render the usage of public clouds impossible.
•A private cloud is established in a dedicated data
center by the company itself or by an external
provider. The services offered by this cloud are
only accessible by one company.

12. Hybrid Cloud:-
•A single or combination of SaaS,IaaS,PaaS offerings
shall be offered exclusively to companies with high
privacy and security requirements while others shall
be shared between multiple companies to reduce costs
of the offerings and enable a dynamic resource usage
following a pay-per-use pricing model.
•A hybrid cloud integrates services
of public and private clouds and establishes common
management functionality.

13. Evolution & Market Drivers:-

14. As an end-consumer, believe it or not you’ve been using
Cloud for long times
•Keep up Friends
•Share what’s new
•Gmail
•Drive
•Online CRM
•Buy Books online

15. Key Player’s in Market:-
Ec2 Cloud (Elastic Compute)
S3 storage (Simple storage service)
Elastic app Infrastructure
App Platform

App Platform

16. Private Cloud vendors (Data Centers):-
▫IBM
▫Vmware
▫Sun/Oracle
▫3Tera
Hosting players
Hundreds of them around
the world

17. Global Perspective:-
•A Market survey says the cloud market will reach 270 billion
dollars in 2020 estimating that it will hit 143 billion dollars by
2013.
•The top five rankings for markets with the most robust cloud
policies went to Japan, Australia, Germany, the United States, and
France.
•Today there are 100 cloud companies ,in two years there will be
5000.

18. Smart Devices Cloud Connection
• Broad band conectivity
• Run Sophisticated apps
• Rich media and social networking
• Location services
• Accessible by everyone from
anywhere

19. Green IT Strategy via Cloud:-
•In theory, a shared resource like Amazon or Google's
public clouds can have higher utilization and thus
greater power efficiency.
•Cloud-based enterprise mobility ! It reduces the
significance of device operating systems, providing
easier multi-vendor support and enabling access to
applications from mass-market handsets; it reduces
the amount of data stored on the device

20. Pro’s & Con’s:-
Pro’s
•Cost reduction
•It’s scalable
•Easier collaboration
•Increased Storage Capacity
•Backup and Recovery
•Cloud is environmentally friendly

21. Con’s
•Availability
•Data mobility and ownership
•Technical Difficulties and Downtime
•Increased Vulnerability

22. Conclusion:-
•Despite its disadvantages and the fact that it is
still in an infant age, cloud computing remains
strong and has great potential for the future. Its
user base grows constantly and more big players
are attracted to it, offering better and more fine
tuned services and solutions.
•If you decide that your business should be in the
cloud, be sure to take the time to layout your
transition plan and determine how you will make
progress. At the end of the day, moving to the
cloud is a big decision that should not be taken
lightly
