3. Cloud Computing is the technology in which various types
of services are provided using the Internet. These services can
be anything, whether it is some kind of software or storage
space is to be given on the server or any other service. Cloud
computing means providing any kind of computing service on
the demand of the user through the Internet.
Example : Many examples of Cloud Computing Technology
exist in the world today. Of which we present to you some
selected famous examples.
1. Facebook
2. Youtube
3.Gmail
INTRODUCTION

5. Cloud Computing Architecture
 The two most significant components of cloud computing
architecture are known as the front end and the back end.
 The front end is the part seen by the client, i.e. the computer
user. This includes the client’s network (or computer) and the
applications used to access the cloud via a user interface such
as a web browser.
 The back end of the cloud computing architecture is the
‘cloud’ itself, comprising various computers, servers and data
storage devices.

8. On the basis of deployment
1. Public Cloud Computing :
The public cloud is accessible to everyone and is managed by
the service provider. Public cloud services are sometimes free or
charged very little for them.
Amazon Web Services (AWS), Microsoft Azure are all examples
of Public Cloud Computing.

9. 2. Private Cloud Computing :
In Private Cloud Computing, services and networks are stored
on a private cloud. In this, the user does not have to share his
cloud storage with any other person.
Example: Google Drive is an example of Private Cloud
Computing. Here all your data is protected with your email ID and
password and in this your drive cannot be used by anyone other
than you.

10. 3. Community Cloud Computing :
Community Cloud Computing is available to only one group of
people. Apart from this, no other external person can access this
data.
Example : For a government office, only its employees can use
the data available on its site or only the students of that university
can use the material available on the website created by a
university.

11. 4. Hybrid Cloud Computing :
In hybrid cloud both private cloud and public cloud are
used. If some content on a site is available only to registered
people and some content is available to public then such cloud is
called hybrid cloud.

12. On the basis of service provider
1. Iaas (Infrastructure as a service)
In this type of service, the computing power, storage,
software, network power and all other control of the cloud is
with the user. This service is basically used for business.
The biggest example of this is VPS i.e. Virtual Private Server. In
which you get software and network as well as computing
power.

13. 2. Paas (Platform as a service)
In PaaS (Platform as a service), the user gets only one
platform. Which can have either storage or computing power, in
which you do not control things completely, they can be
controlled only by the cloud provider.
Its examples are Gmail, Rediff, Yahoo etc.

14. 3. Saas (Software as a service)
In SaaS (Software as a service) you get only one software
hosted on a remote server which is used for a certain
task. These types of services are mostly used by small
businesses. This type of service can contain any kind of
software such as
Google Docs Online or Google GSuite etc. These are all
examples of SaaS.

15. Pros
1. Large storage :
In this, all your data is saved on the cloud, in which you can
increase your storage according to your wish and need.
2. Ease of Data Access :
The biggest advantage of storing data on the cloud is that
you can access it from anywhere and from any device. If you
need only internet connection, using which you can access your
cloud.
3. Large processing power :
On Cloud Computing, you do not have to compromise with
the processing power, in this you can buy as much processing
power as you want.

16. 4. Less price :
In Cloud Computing, you can buy storage space as per
your requirement and you have to pay only that amount. For
example, if you need 20 GB of storage, then you can buy the
same amount of space by paying 20 GB. For this you will not
have to buy 500 GB hard disk.

17. Conclusion
Cloud computing is recently new technological development
that has the potential to have a great impact on the world. It
has many benefits that it provides to it users and businesses.
For example, some of the benefits that it provides to
businesses, is that it reduces operating cost by spending less on
maintenance and software upgrades and focus more on the
businesses it self.
