3. What is cloud computing ?

4. “Any Situation In Which Computing Is Done In A
Remote Location (out in the clouds) Rather
than on your desktop or portable Device.”

5. Cloud Computing
 Low Cost For User And Providers.
 Independence Of Device And Software.
 Efficient Utilization Of all the resources.
 Ability to continusly add new users and
applications .
 Data is secure with policies to
protect its security

6. What is Cloud Computing
 Shared pool of configurable computing resources
 On-demand network access
 Provisioned by the Service Provider

7. What we can do with it?
Its all in cloud:
 Email
 Database
 Project Management
 Storage online
 Voicemail

8. CLOUD ARCHITECTURE

9. Key Charecteristics
 Data Stored on the cloud
 Software and services in the cloud-acess
via web brosers.
 Acessible from any devices.

10. Major Cloud Computing Services
 SaaS(Software as a Service)
 PaaS(Platform as a Service)
 IaaS(Infrastructure as a Service)

11. Cloud Service Layers - Example
Software as a
Service (SaaS)
Platform as a
Service (PaaS)
Infrastructure as
a Service (IaaS)

12. CLOUD TYPES
Private
Public
Hybrid

13. Public Cloud
Public Cloud: the services are delivered to the
client via the Internet from a third party
service provider.
Example: Amazon

14. Private Cloud
Private Cloud: These services are
managed and provided within the
organization.
Example: HP Data Centers

15. Hybrid Cloud

16. Product of Cloud Computing
Google App Engine
Amazon EC2 & S3
Windows Azure
Google App
Panda Cloud

17. The Cloud Venders
The Public Cloud Vendors
• ▫Amazon
• ▫Google
• ▫Microsoft
Private Cloud vendors (Data Centers)
• ▫IBM
• ▫Vmware

18. Amazon web service
Several large Web companies are now
exploiting the fact that they have data storage
capacity that can be hired out to others.
Amazon is one of the foremost and most
reputed Cloud Computing service provider,Which
includes:
Simple Storage Service (S3)
Elastic Compute Cloud (EC2)
SimpleDB

20. Advantages
1. Lower computer costs
2. Improved performance
3. Reduced software cost
4. Instant software updates
5. Affordable
6. Unlimited storage capacity
7. Increased data reliability
8. Universal document access
9. Latest version availability
10.Device independance

21. Disadvantage
1. Requires a constant Internet connection
2. Does not work well with low-speed connections
3. Features might be limited
4. Can be slow
5. Stored data might not be secure
6. Stored data can be lost
7. Harder to know who can alter the data and
where they come from.

22. conclusion
 Thus cloud computing provide a super-
computing power.This cloud of computer
extends beyond a single computer or
enterprise.
 In Future The Security and Reliability shall Be
Improved By the Introduction of certain
globally accepted standard.
