Introduction

• Isn't PC-centric; “document centric”.

• Software programs stored on servers accessed via the internet.

• Edit and collaborate documents in real time.

What is cloud computing?

• Relies on sharing computing resources

• Cloud computing- internet based computing

• Servers, storage and applications are delivered through internet.

• It is comparable to grid computing

Why cloud computing?

• User centric

• Task centric

• Powerful

• Accessible

• Intelligent

• programmable

Cloud Architecture

• Users connect to the cloud from personal

computers or portable- over the internet.

• Cloud is seen as single application, device, or

document

• Hardware in cloud is invisible.

Cloud service models

1. Software as a Service (SaaS)

2. Platform as a Service(PaaS)

3. Infrastructure as a service(IaaS)

SaaS

• Provider will license user

• E.g.: Google Apps, Microsoft Office 365, Onlive, GT Nexus,

Marketo, TradeCard.

• Prons: 1.free paid

2.accessible

3.collaborative working

• Cons: Generic applications not always suitable for business

use…

PaaS

• Cloud provider deliver a “computing platform”

• E.g., cloud foundry, Google app engine, Mendix, OrangeScape

• Pros: 1. Rapid development at low cost

2.private or public deployment

• Cons: limits developer to provider languages and tools.

IaaS

• Offers virtual machines and other resources.

• Ex.: Amazon EC2, HP cloud, SingleHop

Types of Cloud Storage

• Public cloud

• Private cloud

• Hybrid cloud

• Public cloud: computing resources are provisioned over

the Internet, and third party service provider services as

“utilities”.

• private cloud: it has removed no of objections over

security & issues connected.

• Hybrid cloud: combination of public & private cloud

storage.

Conclusion

• Provide a “super computing power”

• The applications and data served by the cloud are available to broad group of

users.

• So many advantages like lower costs, improved performance, device

independence.
