Cloud computing refers to accessing computational resources like applications and data storage over the internet instead of locally. There are several types of cloud services including Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). Cloud computing provides advantages like reduced costs, increased reliability, and accessibility from any device with an internet connection. However, there are also risks like dependence on cloud providers and potential performance issues. The future of cloud computing is expected to include continued cost reductions and increased adoption across organizations of all sizes for both public and private cloud solutions.

2. WHAT IS CLOUD ??
Infrastructure provided by the service
provider to build internet application.
The service provided by cloud are
categorize
> Software As a Service
> Infrastructure As a Service
> Platform As a Service
> Database As a Service
> Software plus Service

3. Cloud Computing- CONCEPT
 Cloud computing refers to the use and access of multiple server-based
computational resources via a digital network (WAN), Internet connection
using the World Wide Web etc.. Cloud users may access the server resources
using a computer, netbook, pad computer, smart phone, or other device.
 In cloud computing, applications are provided and managed by the cloud
server and data is also stored remotely in the cloud configuration. Users do
not download and install applications on their own device or computer; all
processing and storage is maintained by the cloud server. The on-line services
may be offered from a cloud provider or by a private organization.

5. HISTORY
Cloud computing is a natural evolution of the widespread
adoption of virtualization, service-oriented
architecture, autonomic, and utility computing. Details are
abstracted from end-users, who no longer have need for
expertise in, or control over, the technology infrastructure
"in the cloud" that supports them.
The actual term "cloud" borrows from telephony in that
telecommunications companies, who until the 1990s
offered primarily dedicated point-to-point data circuits,
began offering Virtual Private Network (VPN) services
with comparable quality of service but at a much lower
cost.

6. NEEDS
To reduce the IT operations and
management costs
Cloud model of software architecture.

7. ISSUES RELATED TO CLOUD
COMPUTING
Cloud computing may create a dependence on the provider
(Google, Amazon) and may make it difficult to move to
another platform.
Google itself admits that Google App Engine is targeted at
consumer applications, not businesses.
There’s always the risk that the Cloud provider may change
business models or even go out of business.

8. CHARACTERISTICS
Measured Service
 Rapid Elasticity
On-Demand Self-Service
Ubiquitous Network Access
Resource Pooling

Private Cloud
Community Cloud
Hybrid Cloud
Combined Cloud

12. PROS AND CONS :
ADVANTAGES:
Software as a Subscription
Reduced Software Maintenance
Increased Reliability
Environmentally Friendly
Cost Reduction
Portability/Accessibility

13. DISADVANTAGES:
Bandwidth could bust your budget
App performance could suffer
Data might not be cloud-worthy
Too big to scale

14. Future of CLOUD COMPUTING
 The 55% of respondents believe that cloud computing
has a lower total cost of ownership (TCO).
 74 percent of respondents indicated that cloud
computing would either lead to an increase in hiring or
have no impact, while rest of respondents expected any
decrease in hiring based on cloud adoption.
 39 percent indicating that the cloud would make for
less or more complex environments.

15. Conclusions
•Cloud Computing is the fastest growing part of
IT
• Tremendous benefits to customers of all sizes
• Cloud services are simpler to acquire and scale
up or down

16. Conclusions
•Public clouds work great for some but not all
applications
• Private clouds offer many benefits for internal
applications
• Public and private clouds can be used in
combination
