2. Welcome!!
In the simplest terms, cloud computing
means storing and accessing data and programs over the int
ernet instead of your computers hard drive.
With cloud computing user can access database resources
via the internet from anywhere for as long as they need witho
ut worrying about maintenance.
3. Agenda
1

To study concept of cloud computing.
To know Benefits of cloud computing
To know the types of cloud computing
5. Meaning of cloud computing?
cloud computing
Cloud is related with network or
Internet Or in simple language it is
“Any time Any where” service.
Computer is related with the storage ,
program, data etc...
Cloud computing is both a combination of software and hardware based comput
ing resources delivered as a network service. it make your data safe and secure
and you can access that data any time any where.
6. Basic concept
There are certain services and modules working behind the
scene making cloud computing flexible and accessible to end users. Following are the w
orking modules for cloud computing.
1. Deployment Modules
2. Services Modules
8. Types of cloud computing access
Types
Public cloud
Private cloud
Hybrid cloud
Community
cloud
9. Public cloud
The public cloud allows systems and se
rvices to be easily accessible to the general public cloud may be less secur
e because of its openness e.g. e-mail
10.
11. Private computing
The private cloud allows systems and services
to be accessible with in organization. It offers increased security because of its priva
te nature.
12. Community cloud
The community cloud computing allows systems
and services to be accessible by group of organization.
13. Hybrid cloud
The hybrid cloud is mixture of public
and private cloud. However, the critical activates and performance using
private cloud while the non- critical activates are performed using public
cloud.
14. Service modules
Services models are the reference models
on which the cloud computing is based. These can be categorised into three servi
ces models as listed below.
A. Infrastructure as a services {IAAS}
B. Platform as a service { PAAS}
C. Software as a services {SAAS}
15. Infrastructure as a services
{IAAS}
IAAS is the delivery of technology Infrasture as ON dema
nd scalable service. IAAS provides access to fundamental resource such as phys
ical machines, virtual machines, virtual storage, etc…
16. Platform as a service
{PAAS}
PAAS provides the runtime enviro
nmental for application, development & deployment tools , etc..
it provides all of the facilities re
quired to support the complete life cycle of building and delivering
web application and services entirely from the internet.
17. Software as a service
{SAAS}
Saas models allows to use software
application as a services to end users.
SaaS is a software delivery methodology that provides lice
nsed multi tenant access to software and it functions remotely as a web-
based services.
