Cloud computing allows users to access applications and files from any device with an internet connection. It provides computation resources, software, data access, and storage through remote servers rather than local hardware. There are different types of cloud deployment models including public, private, hybrid, and community clouds that are distinguished by their intended user base. The cloud architecture consists of a front-end interface and back-end servers that host applications and store data.

2. What is Cloud Computing?
 Cloud computing is a technology that uses
the internet and central remote servers to
maintain data and applications.
 Cloud computing allows consumers and
businesses to use applications without
installation and access their personal files at
any computer with internet access.

3. Example
 A simple example of cloud computing is
Yahoo mail, Gmail, or Hotmail etc.
 You don’t need a software or a server to use
them. All a consumer would need is just an
internet connection and you can start
sending emails.

5. What it provides
 computation,
 software,
 data access, and
 storage resources
without requiring cloud users to know the location and
other details of the computing infrastructure.

7. Community Cloud
Community cloud shares
infrastructure between
several organizations from a
specific community with
common concerns (security,
compliance, jurisdiction,
etc.), whether managed
internally or by a third-party
and hosted internally or
externally.

8. Public Cloud
A public cloud is
established where several
organizations have similar
requirements and seek to
share infrastructure so as
to realize some of the
benefits of cloud
computing.

9. Private Cloud
Private cloud is
infrastructure operated
solely for a single
organization, whether
managed internally or by
a third-party and hosted
internally or externally.

10. Hybrid Cloud
Hybrid cloud is a
composition of two or
more clouds (private,
community, or public)
that remain unique
entities but are bound
together, offering the
benefits of multiple
deployment models.

11. Cloud Computing Architecture
 The architecture has two sections: the front end and
the back end.
 They connect to each other through a network, usually
the Internet.
 The front end is the side the computer user, or client,
sees.
 The back end is the "cloud" section of the system.

12. Front End
 The front end includes the client's computer (or
computer network) and the application required to
access the cloud computing system.
 Not all cloud computing systems have the same user
interface. Services like Web-based e-mail programs
leverage existing Web browsers like Internet Explorer
or Firefox.
 Other systems have unique applications that provide
network access to clients.

13. Back End
 On the back end of the system are the various
computers, servers and data storage systems that
create the "cloud" of computing services.
 In theory, a cloud computing system could include
practically any computer program you can imagine,
from data processing to video games. Usually, each
application will have its own dedicated server.

15. Cloud Computing Concerns
 Perhaps the biggest concerns about cloud computing
are security and privacy. The idea of handing over
important data to another company worries some
people. Corporate executives might hesitate to take
advantage of a cloud computing system because they
can't keep their company's information under lock and
key.
