This document provides an overview of cloud computing. It defines cloud computing as network-based computing that takes place over the internet using integrated hardware, software, and internet infrastructure. Cloud computing is characterized by services being remotely hosted and available from anywhere, and having a utility-based payment model. The document outlines the three main cloud service models: Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). It also discusses some of the opportunities of cloud computing, such as flexibility and scalability, as well as advantages like lower costs, improved performance, and unlimited storage. Finally, it briefly introduces the different types of cloud models including private, hybrid, and public

2. WHAT IS CLOUD COMPUTING

3. WHAT IS CLOUD COMPUTING?
• Cloud Computing is a general term used to
describe a new class network based computing
that takes place over the internet,
* Basically a step on from utility computing
* A collection/group of integrated and
networked hardware, software and internet
infrastructure(called a platform)
*Using the internet for communication and
transport provides hardware, software and
networking services to clients

4. CLOUD SUMMARY
• Cloud computing is an umbrella term used to refer to
internet based development and services
• A number of characteristics define are hosted on
remote infrastructure:
- Remotely hosted: Services or data are hosted on
remote infrastructure.
- Ubiquitous: Services or data are available from
anywhere.
- Commodified : The result is a utility computing model
similar to traditional utilities, like gas and electricity-
you pay for what you would want

5. CLOUD COMPUTING
CHARACTERISTICS
• COMMON CHARACTERISTICS
Massive scale Geographic Distribution
Service Orientation Virtualization
Low Cost Software Advance security

6. Essential Characteristics
-
On Demand Self- Service
Broad Network Access Rapid Elasticity
Resource Pooling Measured Service

7. CLOUD SERVICE MODELS
CLOUD SERVICES MODELS
SAAS PASS IAAS
SAAS= SOTWARE AS A SERVICE
PASS= PALTFORM AS A SERVICE
IAAS= INFRASTRUCTURE AS A SERVICE

8. SOFTWARE AS A SERVICE(SAAS):-
Saas model allows use software applications as a service to end
users
PLATFORM AS A SERVICE(PAAS):-
PaaS provides the runtime environment for applications,
development & development tools
INFRASTRUCTURE AS A SERICE (IAAS):-
IaaS provides access to fundamental resources such as physical
machine ,virtual machines

10. OPPORTUNITIES AND CHALLENGES
• The use of the cloud provides a number of
opportunities:-
* it enables services to be used without any
understanding of their infrastructure
* Cloud computing works using economic
of scale
*Data and services are stored remotely but
accessible from “ anywhere”

11. BENEFITSADVANTAGES
