Service Models are the reference models on which the Cloud Computing is based.These can be categorized into
three basic service models first is
SaaS
In a Software as a Service model a pre-made application, along with any required software, operating system, hardware, and network are provided.Basically SaaS model allows to use software applications as a service to end users.
PaaS provides the runtime environment for applications, development & deployment tools, etc. which means
in PaaS an operating system, hardware, and
network are provided, and the customer installs or develops its own software and applications.
The IaaS model provides just the hardware and network; the customer installs or develops its own operating systems, software and applications.

In PUBLIC CLOUD
It allows systems and services to be easily accessible to the general public. Public cloud may be
less secure because of its openness, for example, e-mail.
In PRIVATE CLOUD
It allows systems and services to be accessible within an organization. It offers increased
security because of its private nature.
In COMMUNITY CLOUD
It allows systems and services to be accessible by group of organizations.
And
The Hybrid Cloud is mixture of public and private cloud. However, the critical activities are performed using private cloud while the non-critical activities are performed using public cloud.
I made this for my sweet little angel ^.^

3. INTRODUCTION
Cloud computing is the use
of computing resources (hardware and
software) that are delivered as a service
over the Internet.

5. When you store your photos online instead
of on your home computer, or use webmail
or a social networking site, you are using a
“cloud computing” service.
6. Cloud Computing promotes availability and is
composed of
Five essential characteristics
Three service models and
Four deployment models
7. CHARACTERISTICS
There are five key characteristics of cloud
computing:
On-demand self service
Broad network access
Resource pooling
Rapid elasticity and
Measured service
8. SERVICE MODELS
Service Models are the reference models on which
the Cloud Computing is based. These can be
categorized into three basic service models:
Software as a Service (SaaS)
Platform as a Service (PaaS) and
Infrastructure as a Service (IaaS)
9. Cloud Clients
Web browser, mobile app, clients
SaaS
Application CRM, Email, games, virtual desktop
PaaS
Database, web server, deployment
tools
IaaS
Virtual machines, storage, networks
Platform
Infrastructure
10. DEPLOYMENT MODELS
Deployment models define the type of access to
the cloud. These are:
Private cloud
Community cloud
Public cloud and
Hybrid cloud
11. PURPOSE OF CLOUD
COMPUTING
By using the Cloud infrastructure on “pay as used and on
demand”, all of us can save in capital and operational
investment!
Clients can:
Put their data on the platform instead of on their own
desktop PCs and/or on their own servers.
They can put their applications on the cloud and use the
servers within the cloud to do processing and data
manipulations etc.
13. DISADVANTAGES OF CLOUD
COMPUTING
Requires a constant Internet connection
Does not work well with low-speed connections
Features might be limited
Stored data might not be secure
