According to
Wikipedia?
Cloud
computing is the on-demand availability of computer system resources, especially
data storage (cloud storage) and computing power, without
direct active management by the user. Large clouds often have
functions distributed over
multiple locations, each location being a data center. Cloud computing relies on sharing of resources to achieve
coherence and typically uses a "pay-as-you-go" model,
which can help in reducing capital expenses but may
also lead to unexpected operating expenses for
users.
From <https://en.wikipedia.org/wiki/Cloud_computing>
According to
IBM website?
Cloud
computing is on-demand access, via the internet, to computing
resources—applications, servers (physical servers and virtual
servers), data storage, development tools, networking capabilities,
and more—hosted at a remote data center managed
by a cloud services provider (or CSP). The CSP makes these resources
available for a monthly subscription fee or bills them according to usage.
Compared
to traditional on-premises IT, and depending on the cloud services you select,
cloud computing helps do the following:
·
Lower IT costs: Cloud lets you offload some or most of the costs and effort
of purchasing, installing, configuring, and managing your own on-premises
infrastructure.
·
Improve agility and time-to-value: With
cloud, your organization can start using enterprise applications in minutes,
instead of waiting weeks or months for IT to respond to a request, purchase and
configure supporting hardware, and install software. Cloud also lets you
empower certain users—specifically developers and data scientists—to help
themselves to software and support infrastructure.
·
Scale more easily and cost-effectively: Cloud
provides elasticity—instead of purchasing excess capacity that sits unused
during slow periods, you can scale capacity up and down in response to spikes
and dips in traffic. You can also take advantage of your cloud provider’s
global network to spread your applications closer to users around the world.

Simply
put, cloud computing is the delivery of computing services—including servers,
storage, databases, networking, software, analytics, and intelligence—over the
Internet (“the cloud”) to offer faster innovation, flexible resources, and
economies of scale. You typically pay only for cloud services you use, helping
lower your operating costs, run your infrastructure more efficiently and scale
as your business needs change.

According to
Google website?
What is Cloud Computing?
Understanding
the types of cloud computing resources can be time-consuming and costly.
Enterprises need to buy physical servers and other infrastructure through
procurement processes that can take months, and support the architecture of
cloud computing. The acquired systems require a physical space, typically a
specialized room with sufficient power and cooling. After configuring and
deploying the systems, enterprises need expert personnel to manage them.
This
long process is difficult to scale when demand spikes or business expands.
Enterprises can acquire more computing resources than needed, ending up with
low utilization numbers.
Cloud
computing addresses these issues by offering computing resources as scalable,
on-demand services. Learn more about Google Cloud, a suite of cloud computing service models offered by Google.

What Is Cloud Computing?
Cloud
computing is the delivery of different services through the Internet. These
resources include tools and applications like data storage, servers, databases,
networking, and software.
Rather
than keeping files on a proprietary hard drive or local storage device, cloud-based
storage makes
it possible to save them to a remote database. As long as an electronic device
has access to the web, it has access to the data and the software programs to
run it.
Cloud
computing is a popular option for people and businesses for a number of reasons
including cost savings, increased productivity, speed and efficiency,
performance, and security.
KEY
TAKEAWAYS
·
Cloud computing is the delivery of different services through the
Internet, including data storage, servers, databases, networking, and software.
·
Cloud storage has grown increasingly popular among individuals who
need larger storage space and for businesses seeking an efficient off-site data
back-up solution.
·
Cloud-based storage makes it possible to save files to a remote
database and retrieve them on demand.
·
Services can be both public and private—public services are
provided online for a fee while private services are hosted on a network to
specific clients.
·
Cloud security has become an increasingly important field in IT.
Understanding Cloud Computing
Cloud
computing is named as such because the information being accessed is found
remotely in the cloud or a virtual space. Companies that provide cloud services
enable users to store files and applications on remote servers and then access
all the data via the Internet. This means the user is not required to be in a
specific place to gain access to it, allowing the user to work remotely.
Cloud
computing takes all the heavy lifting involved in crunching and processing data
away from the device you carry around or sit and work at. It also moves all of
that work to huge computer clusters far away in cyberspace. The Internet
becomes the cloud, and voilà —your data, work, and applications are available
from any device with which you can connect to the Internet, anywhere in the
world.
Cloud
computing can be both public and private. Public cloud services provide their
services over the Internet for a fee. Private cloud services, on the other
hand, only provide services to a certain number of people. These services are a
system of networks that supply hosted services. There is also a hybrid option,
which combines elements of both the public and private services.

local drives. The data can be anything such as files, images, documents, audio,
video, and more.
There
are the following operations that we can do using cloud computing:
·
Developing new applications and services
·
Storage, back up, and recovery of data
·
Hosting blogs and websites
·
Delivery of software on demand
·
Analysis of data

Why Cloud Computing?
Small
as well as large IT companies, follow the traditional methods to provide the IT
infrastructure. That means for any IT company, we need a Server Room that
is the basic need of IT companies.
In
that server room, there should be a database server, mail server, networking,
firewalls, routers, modem, switches, QPS (Query Per Second means how much
queries or load will be handled by the server), configurable system, high net
speed, and the maintenance engineers.
To
establish such IT infrastructure, we need to spend lots of money. To overcome
all these problems and to reduce the IT infrastructure cost, Cloud Computing
comes into existence.

Cloud
Computing has become the buzzing topic of today's technology, driving
mainly by marketing and services offered by prominent corporate organizations
like Google, IBM & Amazon. Cloud computing is the next stage to evolve the
Internet. Though for some people, "Cloud Computing" is a big deal, it
is not. In reality, cloud computing is something that we have been using for a
long time; it is the internet facility, along with the associated standards
that provide a set of web-services to users. When users draw the term
'Internet' as a "cloud", they represent the essential characteristics
of cloud computing.

Why this cloud technology?
The
small and extensive IT companies follow the old traditions of managing IT
infrastructure, i.e., server room, to keep all the details and maintain that
server. In a word, it is a server room consists of database servers, mail
server, firewalls, routers, switches, QPS (Query per second) & Load
handler, and other networking devices along with server engineers. To provide
such IT infrastructure, a huge amount of money has to spend. So, to reduce the
IT infrastructure cost, Cloud Computing technology came into play.

<https://w3schools.in/cloud-computing/>
How cloud computing works?
The
cloud has to be divided into different layers. These layers are
the front-end and back-end layers. The Front-end layer is
that part of the cloud with which users can interact with. For example, when we
log in to our Gmail account, we see the UI (user interface) where everything
works on event-driven buttons and graphics. Similarly, the software also runs
in the front end of the cloud. Again, the back-end comprises hardware as well
as software that delivers the back-end data from the database to the front end.

Cloud
computing is the on-demand delivery of IT resources over the Internet with
pay-as-you-go pricing. Instead of buying, owning, and maintaining physical data
centers and servers, you can access technology services, such as computing power,
storage, and databases, on an as-needed basis from a cloud provider like Amazon
Web Services (AWS).

What is cloud computing?
Cloud
computing and associated solutions provide access through the web to computing
resources and products, including development tools, business applications,
compute services, data storage, and networking solutions. These cloud services
are hosted at a software vendor’s data center and managed by the cloud services
provider or onsite at a customer's data center.

Cloud computing defined
In
simple terms, cloud computing allows you to rent instead of buy your IT. Rather
than investing heavily in databases, software, and hardware, companies opt to
access their compute power via the internet, or the cloud, and pay for it as
they use it. These cloud services now include, but are not limited to, servers,
storage, databases, networking, software, analytics, and business intelligence.
Cloud
computing provides the speed, scalability, and flexibility that enables
businesses to develop, innovate, and support business IT solutions.

Cloud computing basics
When
a company chooses to “move to the cloud,” it means that its IT infrastructure
is stored offsite, at a data center that is maintained by the cloud
computing provider. An industry-leading cloud provider has the responsibility for
managing the customer’s IT infrastructure, integrating applications, and
developing new capabilities and functionality to keep pace with market demands.
For
customers, cloud computing offers more agility, scale, and flexibility. Instead
of spending money and resources on legacy IT systems, customers are able to
focus on more strategic tasks. Without making a large upfront investment, they
can quickly access the computing resources they need—and pay only for what they
use.

What is the cloud?
Moving
to the cloud. Running in the cloud. Stored in the cloud. Accessed from the
cloud: these days is seeming like everything is happening “in the cloud”. But
what exactly is this nebulous concept?
The
short answer is that it's somewhere at the other end of your internet
connection – a place where you can access apps and services, and where your
data can be stored securely. The cloud is a big deal for three reasons:
1. It doesn't
need any effort on your part to maintain or manage it.
2. It's
effectively infinite in size, so you don't need to worry about it running out
of capacity.
3. You can
access cloud-based applications and services from anywhere – all you need is a
device with an internet connection.

How cloud computing works?
With
a cloud app, you just open a browser, log in, and start working.
That
means a field sales representative using cloud-based
CRM can
get all the information they need from their mobile device. Contact notes can
be updated in real time so they are always fresh and complete and available to
others – no more waiting to get back to the office to type it in. And sales
managers know exactly which deals will close and when, from their desktop
machines in their offices, or their tablets or phones when they are out and
about.

Cloud
computing has arrived, and everyone is interested in learning more. Your users
and customers are used to their personal mobile applications, like Facebook and
Google Docs, where they can interact and work anywhere, anytime. But there is
much more behind cloud computing than just a modern web interface. Great
response time, data storage, information access, reliability, and security are
all vital to any business looking into a possible “move to the
cloud.” More than likely your peers have told you of their success with
cloud computing and how they have the most current technology, much more
flexibility, or lower IT costs.
