What is Cloud Computing?

As defined by Amazon Web Services or AWS, ‘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).’ 

So, cloud computing refers to an abstraction of storage, computing, and network infrastructure integrated together as a platform that enables you to deploy your systems and applications quickly and scalable on the go. 

Most frequently, when people casually refer to “the cloud,” they are referring to the major IaaS providers, such as Microsoft Azure, Google Cloud, and AWS (Amazon Web Services). The developer tools, serverless computing, machine learning services and APIs, data warehouses, and thousands of more services that go far beyond infrastructure have all grown into enormous ecosystems. Agility is a major advantage of SaaS and IaaS. Clients can quickly scale the cloud resources they use up or down according to their needs while gaining new capabilities nearly immediately without making financial investments in hardware or software.

Cloud computing facilitates businesses with big data repositories and allows them to focus on other more important aspects of the business so that they can improve their efficiencies and, eventually ROIs. 

Types of Cloud Computing Models

Not every cloud is the same, and not everyone should use the same kind of cloud computing. The development of numerous models, varieties, and services has made it possible to provide the ideal solution for your requirements.

You are required to identify the type of cloud deployment or cloud architecture first, on which your cloud services are to be implemented. The three different types include the private cloud, the public cloud, and the hybrid one. 

Private Cloud 

The model of cloud computing where the resources and services are exclusively used by a single user organization, the cloud is referred to as the private cloud. That means it is dedicated to a single organization. A company can have its private cloud installed at its on-site data center. To host their private clouds, many companies hire third-party service providers. In a private cloud, the services and infrastructure are maintained over a private network.

Some popular private cloud service providers include Azure Stack and HPE GreenLake.

Public Cloud

Third-party cloud service providers, who distribute their computing resources, such as servers and storage, over the Internet, own and run public clouds. A prime illustration of a public cloud is Microsoft Azure. With a public cloud, the cloud provider owns and manages all of the hardware, software, and other supporting infrastructure. You access these services and manage your account using a web browser.

 Apart from Microsoft Azure, the cloud giants Amazon Web Services (AWS) and Google Cloud Platform are the most common examples of Public Cloud service providers. 

Hybrid Cloud

As the name suggests, a hybrid cloud is a blend of both the public cloud and the private cloud that are integrated together by the technology that enables applications and data to be shared between them. The hybrid cloud provides greater deployment options and substantial flexibility and also allows you to optimize your existing security, infrastructure, and compliance, all this by allowing you to move data and applications between public and private clouds. 

Some of the most popular cloud service providers include Google Anthos, Azure Arc, and AWS Outposts.

Types of Cloud Services

Infrastructure as a Service(IaaS)

This is the most fundamental category of cloud services where you can rent IT infrastructure that may include operating systems, storage, networks, Virtual Machines, and servers; all these are offered by a cloud service provider on a pay-as-you-go pricing model. 

Software as a Service (SaaS)

Software as a service (SaaS) is a delivery method for software programs over the Internet, usually by subscription. SaaS applications are hosted and managed by cloud service providers, who also take care of any maintenance tasks like software upgrades and security patches. Internet connections are made by users to the program.

Platform as a Service (PaaS)

It refers to the type of cloud computing services that offer an on-demand environment for creating, testing, supplying, and maintaining software applications. It is specifically designed to simplify the processes of creating mobile or web applications without the need for installing or managing the underlying infrastructure of the network, storage, servers, and databases required for the development. 

Serverless Computing

It is specifically meant to facilitate the development of app functionality without the need to look after servers and infrastructure. The cloud provider looks after capacity planning, the setup, and server management for you. 


By now, you have got an overview of what cloud computing is all about. To dive deep into the concepts of cloud computing and make your career go places, just take up an online training course from a good training institute such as Simplilearn.
