Cloud computing provides on-demand access to shared computing resources over the internet. It allows users to access files, applications, and storage from any device. The term cloud refers to the internet in diagrams. There are private, public, and hybrid cloud models. Advantages include worldwide access, increased storage, easy setup, automatic updates, and reduced costs. Disadvantages can include downtime if the internet is offline, security issues with hackers accessing data, high data transfer costs, and inflexibility changing cloud providers. Popular cloud companies include Apple, IBM Smart Cloud, and Google Cloud.

3.  Cloud computing is a type of Internet-based
computing that provides shared computer
processing resources and data to computers and
other devices on demand.
It can also be defined as the practice of using a
network of remote servers hosted on the Internet
to store, manage, and process data, rather than a
local server or a personal.
Cloud computing is a model for enabling
convenient, on-demand network access to a
shared pool of configurable computing resources
(e.g., networks, servers, storage, applications,
and services)

6. Origin Of Cloud Computing
The origin of the term Cloud Computing is unclear. The
word "cloud" is commonly used in science to describe
a large agglomeration of objects that visually appear
from a distance as a cloud and describes any set of
things whose details are not further inspected in a
given context. Another explanation is that the old
programs that drew network schematics surrounded
the icons for servers with a circle, and a cluster of
servers in a network diagram had several overlapping
circles, which resembled a cloud.

7. Private cloud:
Private cloud is cloud infrastructure operated solely for a single
organization, whether managed internally or by a third-party, and
hosted either internally or externally.
Public cloud:
A cloud is called a "public cloud" when the services are rendered
over a network that is open for public use. Public cloud services
may be free.
Hybrid cloud:
Hybrid cloud is a composition of two or more clouds (private,
community or public) that remain distinct entities but are bound
together, offering the benefits of multiple deployment models.

8. Advantages Of Cloud Computing :-
 Worldwide Access:-
Cloud computing increases mobility, as you can
access your documents from any device in any part
of the world. For businesses, this means that
employees can work from home or on business trips,
without having to carry around documents.
More Storage:-
In the past, memory was limited by the particular
device in question. If you ran out of memory, you
would need a USB drive to backup your current
device. Cloud computing provides increased storage,
so you won’t have to worry about running out of
space on your hard drive.

9.  Easy Set-Up:-
You can set up a cloud computing service in a matter of
minutes. Adjusting your individual settings, such as
choosing a password or selecting which devices you
want to connect to the network, is similarly simple.
Automatic Updates:-
The cloud computing provider is responsible for making
sure that updates are available. You just have to
download them.
Reduced Cost:-
Cloud computing is often inexpensive. The software is
already installed online, so you won’t need to install it
yourself. There are numerous cloud computing
applications available for free, such as Dropbox.

10. Disadvantages:-
Cloud Computing Is Not the Solution for
Everything:-
 Cloud computing is not solution of everything we will
study what problems we can face by using it.

11. Possible Downtime:-
 Cloud computing makes your small business
dependent on the reliability of your Internet
connection. When it's offline, you're offline. If your
internet service suffers from frequent outages or
slow speeds, cloud computing may not be suitable
for your business.

12. Security Issues:-
 How safe is your data? Cloud computing
means internet computing. So you should not be
using cloud computing applications that involve
using or storing data that you are not comfortable
having on the internet.
Keep in mind also that your cloud data is accessible
from anywhere on the internet, meaning that if a data
breach occurs via hacking, a disgruntled employee,
or careless username/password security,
your business data can be compromised.

13. Cost:-
 At first glance, a cloud computing application may appear to
be a lot cheaper than a particular software solution installed
and run in-house, but you need to be sure you're
comparing apples and apples.
To be sure you're saving money, you have to look closely
at the pricing plans and details for each application, taking
into account possible future expansion.
If your business involves
transferring large amounts
of data, be aware that while
transferring data to the
cloud (inbound) is free,
outbound data transfers
over the basic monthly
allowance are charged on a per GB
GB basis .

14. Inflexibility:-
 The inflexibility of some cloud apps can be another
serious disadvantage of cloud computing. Be careful
when you're choosing a cloud computing vendor that
you're not going to become a "forever" customer
because their applications and/or data formats do not
allow easy transfer/conversion of information into other
systems
