This document provides an overview of cloud computing. It defines cloud computing as internet-based computing where software, storage, and applications are delivered through the internet. The document outlines the cloud computing architecture and three main service models: Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). It also discusses the advantages of cloud computing in providing powerful and accessible computing resources at lower costs, while allowing for collaborative work. Types of cloud storage including public, private, and hybrid clouds are also introduced.

2. Outline
• Introduction
• What is cloud computing
• Why cloud computing
• Cloud Architecture
• Cloud service models
• Types of Cloud Storage
• Advantages
• Dis advantages
• conclusion

3. Introduction
• Isn't PC-centric; “document centric”.
• Software programs stored on servers accessed via the internet.
• Edit and collaborate documents in real time.

4. 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

5. Why cloud computing?
• User centric
• Task centric
• Powerful
• Accessible
• Intelligent
• programmable

6. 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.

7. Cloud service models
1. Software as a Service (SaaS)
2. Platform as a Service(PaaS)
3. Infrastructure as a service(IaaS)

8. 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…

9. 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.

10. IaaS
• Offers virtual machines and other resources.
• Ex.: Amazon EC2, HP cloud, SingleHop

11. Types of Cloud Storage
• Public cloud
• Private cloud
• Hybrid cloud

12. • 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.

13. 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.
