Cloud computing is a type of computing that relies on sharing computing resources over the Internet rather than local hardware. It provides software, platforms, and infrastructure as online services with advantages like lower costs, improved performance, universal access, and unlimited storage. However, it also has disadvantages like requiring a constant Internet connection and potential security and performance issues if the connection is slow.

3. INTRODUCTION
• With traditional desktop computing, we run copies of software
programs on our own computer. The documents we create are stored
on our own pc.
• With cloud computing, the software programs one use aren’t run
from one’s personal computer, but are rather stored on servers
accessed via the Internet.
• If a computer crashes, the software is still available for others
to use. Same goes for the documents one create; they’re stored
on a collection of servers 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.
• In cloud computing, the word cloud (also phrased as "the cloud") is used as
a metaphor for "the Internet," so the phrase cloud computing means "a
type of Internet-based computing," where different services such as servers,
storage and applications are delivered to an organization's computers and
devices through the Internet.
• Cloud computing is comparable to grid computing, a type of computing
where unused processing cycles of all computers in a network are harnesses
to solve problems too intensive for any stand-alone machine.

5. Why Cloud Computing?
• Cloud Computing Is User Centric
• Cloud Computing Is Task-Centric
• Cloud Computing Is Powerful
• Cloud Computing Is Accessible
• Cloud Computing Is Intelligent
• Cloud Computing Is Programmable

6. Cloud Architecture
 Individual users connect to the cloud
from their own personal computers or
portable devices, over the Internet. To
these individual users, the cloud is seen
as a single application, device, or
document.
 The hardware in the cloud (and the
operating system that manages the
hardware connections) is invisible.

7. Cloud Service Models
 There are mainly 3 service
models given as:
1. Software as a Service (SaaS)
 2. Platform as a Service (PaaS)
 3. Infrastructure as a Service
(IaaS)

8. Some Cloud Service Providers
Utility Computing
Platform as a Service
(PaaS)
Cloud-based User
Applications

9. Cloud Storage
Cloud storage means "the storage of data online in the cloud,"
wherein a company's data is stored in and accessible from multiple
distributed and connected resources that comprise a cloud.
Cloud storage can provide the benefits of greater accessibility and
reliability; rapid deployment; strong protection for data
backup, archival and disaster recovery purposes; and lower overall
storage costs as a result of not having to purchase, manage and
maintain expensive hardware. However, cloud storage does have
the potential for security and compliance concerns.

10. Types of Cloud Storage
1. Public Cloud
2. Private Cloud
3. Hybrid Cloud

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

13. Disadvantages
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.

14. • 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.
