We will discuss the eighth domain of CEH, which is ‘Cloud Computing.’
What is Cloud Computing?
Cloud computing delivers services like databases, software, servers, intelligence, and
storage over the internet to provide faster innovation, economics of scale, and flexible
resources.
To know the importance of cloud computing, let me tell you about life without cloud
computing. Assume you are willing to host a website. You will need to buy a lot of
servers, manage the traffic, maintain and monitor the servers. Now to do so, we need
both extra money and extra human resources.
 If you consider the cost, buying servers is very expensive.
 Troubleshooting server problems can be tedious and can reduce the efficiency of
your business.
 As traffic will change from time to time, your servers will mostly be in the ideal state.
 And storing a lot of data is always a big problem.
 So, to help us overcome these problems, cloud computing has come into existence.
 In simple terms, cloud computing is a tremendous amount of space available online
to store the data, process it, and access it whenever we want.

How does cloud computing work?
Rather than buying complete infrastructure and data centers, organizations
can actually rent storage, applications, and other functionalities from cloud
providers.
Companies using cloud computing services can avoid much of the upfront
cost and complexity of owning and maintaining their own IT infrastructure
and instead only pay for the services they have used.
The providers of cloud computing services can benefit from substantial
economies of scale by delivering the same services to a broader range of
clients.

A few examples of cloud computing
Below are some of the examples of cloud computing we usually use every day.
Zoom: Zoom is a cloud-based audio and video mobile application used on both
iOS and Android devices. You can either start or join a meeting by using zoom.
Microsoft Office 365 and Google Docs: Google Docs and Microsoft Office 365
can be used by online users. We can use Google Docs and Microsoft Office 365
for presentations and maintain and store data.
Aws Lambda: Lambda allows developers to execute code without the need to
provide or manage servers for apps or backend services. The pay-as-you-go
approach scales consistently with an organization in order to accommodate
changes in data use and storage in real-time.

The advantages of cloud computing
Cost: Cloud computing is a lot cheaper. Because in the cloud computing
environment, we need not buy servers and computers, and there is no need to
hire technical staff to maintain these servers.
Speed: The majority of cloud computing services are self-service and on-
demand, which means that even massive quantities of computing resources can
be provisioned within minutes, typically with just a few clicks, which allows
companies a great deal of flexibility.
Security: The majority of cloud providers offer several policies, controls, and
technologies that improve your overall security posture, supporting the
protection of your data, apps, and infrastructure. So, data saved in the cloud is
more secure than files, videos, and images stored on our own devices.
Reliability: Due to the fact that data can be mirrored at multiple redundant sites
within the provider’s network, cloud computing makes data backup, disaster
recovery, and business continuity more convenient and less expensive.

Performance: A large number of cloud computing services run on secure data centers
located globally that are regularly upgraded to the most current generation of fast
and efficient computing hardware. As a result, applications run more smoothly, and
there are greater savings than using a single data center.
Characteristics of cloud computing
Elasticity: If there is massive traffic, we can scale up our services, and when there is
less traffic, we can scale down the services we need, which is also one of the most
significant advantages of cloud computing.
Pay-per-use: By having a physical server of our own, we have to pay ideally without
considering our usage. But with cloud computing, we can only pay for the servers and
resources we have used. This characteristic of cloud computing can save a lot of
money.
Self-service provisioning: Almost any workload type can be accelerated on-demand
by an end-user. IT administrators are no longer needed to manage and provision
computing resources, as end users can provision resources like server time and
network storage.
