Introduction
With the advancement of Internet and computer software technology, a new trend
known as Cloud Computing has emerged and is likely to continue. It is one of the IT industry'
buzzwords. The cloud is a metaphor for the Internet or the infrastructure of communication
between architectural components, and this paper will look briefly into the definitions of cloud
computing, its deployment models, and its service model, as well as a solution as to why ATN
needs to use cloud computing today and how it benefits them.
I.WHAT IS CLOUD COMPUTING TECHNOLOGY?

The popularity of Cloud computing solutions is rapidly increasing. As a result,
they've already been used in a variety of contexts, including social networking, commercial
applications, and content delivery networks. To offer additional information about the cloud
computing paradigm, there are several components that are required for the cloud to work.
A.CLOUD COMPUTING BASICS
1.Basic definition
Cloud computing can be understood simply: huge computing resources such as
software, services, etc. will reside in virtual servers (clouds) on the Internet instead of in
home computers. and offices (on the ground) for people to connect and use when they
need it. With services available on the Internet, businesses do not have to buy and

maintain hundreds or even thousands of computers and software. They just need to focus
on production because someone else takes care of the infrastructure and technology for
them. You can access any resource that exists in the “cloud” at any time and from
anywhere through the Internet.
Thus, cloud computing is just a complete concept for a trend that is not new
because many businesses currently do not have their own servers, PCs only install some
basic software and all depend on the cloud. For example, they sign up for a hosting service
for a company website, hire a revenue management tool from Salesforce.com, get market
survey data from Survey Monkey... Analyze, share and store documents.
2.Who uses cloud computing?
Organizations of all types, sizes, and operating industries are using cloud services
for a wide range of use cases, such as data backup, disaster recovery, email, virtual
desktops, development and software testing, big data analytics, and customer-facing web
applications. For example, healthcare companies are using cloud services to develop more
tailored treatments for patients. Financial services companies are using cloud services to
enhance real-time fraud detection and prevention. And video game makers are using
cloud services to deliver online games to millions of players worldwide.

3.The benefits of cloud computing
a.Fast
The cloud gives you easy access to many technologies so you can innovate faster
and develop nearly anything you can imagine. You can quickly gather resources when
you need them—from infrastructure services, like compute, storage, and databases, to
the Internet of Things, machine learning, data warehousing and analytics, and more.
You can deploy technology services quickly and go from concept to completion

business.

b.Flexible scale
With cloud computing, you don't have to over-provision resources to handle
future peak business operations. Instead, you provide the amount of resources you
actually need. You can scale these resources up or down instantly to increase and
decrease capacity as your business needs change.

c.Cost savings
The cloud allows you to replace capital costs (data centers, physical servers, etc.)
with variable costs and pay only for the IT resources you use. In addition, variable costs
will also be much lower than your out-of-pocket costs due to economies of scale.

d.Deploy globally in minutes
With the cloud, you can expand to new geographies and deploy globally in
minutes. For example, AWS has infrastructure around the world, so you can deploy

applications closer to end users reduces latency and improves their experience.

4.Types of Cloud Computing
The three main types of cloud computing include Infrastructure as a Service,
Platform as a Service, and Software as a Service. Each type of cloud offers different levels
of control, flexibility, and management so you can choose the right set of services for
your needs.
