3. Introduction

Traditional Desktop Computing:
Software and Programs created and used on
one's own computer.

Cloud Computing:
Software and Documents
stored on servers and
accessed via the
Internet.

4. What Is Cloud Computing?

Cloud computing is a type of computing that relies
on sharing computing resources rather than having
local servers or personal devices to handle
applications.
“When it is better to RENT than to BUY”

Computer resources used by companies as a
UTILITY

Cloud used to denote internet in diagrams

5. CHARACTERISTICS

Cost

Device and Location independence

Maintenance

Productivity

Security

Collaboration

6. Cloud Architecture

7. Cloud Service Models
There are mainly 3 service models given as:

8. SaaS

Software-as-a-Service

Cloud providers install and operate
application software in the cloud

Cloud users access software from cloud
clients

SaaS providers:-Google Apps, Microsoft Office
365, Onlive

9. Pros And Cons
• Free or Paid via Subscription
• Accessible from any computer
• No need to install software on every
computer
• Facilitates collaborative working
• Scalability
• Easy updates
• Generic applications not always

10. PaaS
• Platform-as-a-Service
• Cloud providers provide a computing
platform
• Eg: Operating System, Programming
language execution environment, web
server, software development platform
• PaaS providers:- Windows Azure cloud
services, OrangeScape, Force.com

11. Pros And Cons
• Rapid development at low cost
• Public or Private deployment
• Limit developers to provider
languages and tools

12. IaaS
• Infrastructure-as-a-Service
• IaaS providers offer computers
physical or (more often) virtual
machines and other resources
• Eg:- virtual machine disk image
library, firewall, load balancers
• IaaS providers supply these
resources on-demand from their large
pools installed in data-centres

15. Types of Cloud Storage

Public Cloud

Private Cloud

Hybrid Cloud

16. Public Cloud
• Enterprise and storage service provider are
separate
• Data is stored OUTSIDE of enterprise's Data
Centre
• Advantage:
Frees small businesses from the extra cost of
purchasing, managing and maintaining on-
premises Storage Hardware and Software
Resources.

17. Private Cloud
• Cloud Computing platform that is
implemented within a corporate firewall
• Offers same softwares, features, etc to all
the employees
• Advantage:
No issues about security or regulatory
control

18. Hybrid Cloud
• COMBINATION of public and private
cloud
• Critical data resides in enterprise's private
cloud
• Other data is stored and accessible from
some cloud storage provider
• Advantage:
Potential cost savings of public cloud
storage
Security and full control of private cloud

20. Advantages

Lower computer costs.

Improved performance.

Reduced software costs.

Instant software updates.

Unlimited storage capacity.

Increased data reliability.

Universal document access.

Device independence.

21. Disadvantages
• Requires a constant Internet connection.
• Does not work well with low-speed connections.
• Features might be limited.
• Stored data might not be secure.
• Stored data can be lost.

22. Conclusion
• Thus cloud computing provide a super-computing
power .
• This cloud of computers extends beyond a single
company or enterprise.
• The applications and data served by the cloud are
available to broad group of users, cross-enterprise and
cross-platform.
