What Is Cloud Computing?

The on-demand, pay-as-you-go delivery of IT resources through the Internet is known as cloud computing. You can use technological services like computing power, storage, and databases on an as-needed basis from a cloud provider like Amazon Web Services (AWS), rather than purchasing, operating, and maintaining physical data centers and servers.

Who makes use of the cloud?

A wide range of use cases, including data backup, disaster recovery, email, virtual desktops, software development and testing, big data analytics, and customer-facing web apps, are being used by businesses of every size, type, and sector. For instance, healthcare organizations are utilizing the cloud to provide more patient-specific treatments.

Companies that provide financial services use the cloud to support real-time fraud prevention and detection. Additionally, online games are distributed to millions of players worldwide by video game developers via the cloud.

Depending on the cloud services you choose and in comparison, to conventional on-premises IT, cloud computing aids in the following:

  1. Reduced IT costs: By using the cloud, you may offload some or all of the costs and work associated with building, installing, configuring, and administering your own on-premises infrastructure.
  • Enhance responsiveness and time-to-value: Instead of waiting weeks or months for IT to reply to a request, buy and set up supplementary hardware, and install software, your organization may begin utilizing enterprise apps in the cloud in only a few minutes. Cloud also enables you to give some users—more especially, developers and data scientists—free access to software and infrastructure assistance.
  • Scale more easily and affordably: Cloud offers elasticity, allowing you to scale capacity up and down in response to spikes and dips in demand rather than purchasing extra capacity that sits idle during slack periods. You may distribute your applications closer to users all over the world by utilizing the worldwide network of your cloud provider.

Cloud Services Types

No matter the service type, cloud computing services provide users with several benefits, such as:

  • Email backup, storage, and data retrieval
  • developing and evaluating apps
  • streaming audio and video while analyzing data
  • On-demand software delivery

Although it is still a relatively new technology, cloud computing is being utilized by a wide range of industries, including large corporations, small businesses, nonprofit organizations, governmental agencies, and even individual consumers.

Services For Cloud Computing

1)     Software as a Service (SaaS)

Application software that is hosted in the cloud and that users access via a web browser, a dedicated desktop client, or an API that connects with a desktop or mobile operating system is known as SaaS, sometimes known as cloud-based software or cloud apps. Users of SaaS often pay a monthly or yearly membership fee, while some may provide “pay-as-you-go” pricing depending on actual usage.

2)     Platform-as-a-Service, or PaaS

PaaS offers software developers an on-demand platform for managing, running, and developing applications without the expense, complexity, and rigidity of maintaining that platform on-premises. This platform includes hardware, the entire software stack, infrastructure, and even development tools.

3)     Infrastructure-as-a-Service (IaaS)

IaaS offers pay-as-you-go online access to the most basic computer resources, including networking, storage, and physical and virtual servers. With the help of IaaS, end users can scale and downsize resources as needed, eliminating the need for large, upfront capital investments, pointless on-premises or ‘owned’ infrastructure, and over-purchasing resources to account for sporadic spikes in consumption.

Computing Without Servers

Serverless computing, also known as serverless, is a cloud computing model that frees developers to devote all of their time and energy to the code and business logic specific to their applications by offloading all backend infrastructure management tasks to the cloud provider, including provisioning, scaling, scheduling, and patching.

Additionally, serverless executes application code for each request and scales the auxiliary infrastructure up or down automatically based on the volume of requests. Customers never pay for unused capacity when using a serverless since they only pay for the resources used while the application is active.

Gains from Cloud Computing

Companies from all industries can profit from using cloud-based software, which can be accessed by browsers or native apps on any device. Users may seamlessly transfer their files and settings from one device to another as a consequence.

Final Words

Using cloud computing for file access is simply the tip of the iceberg. Users may check their email on any computer and store files using services like Dropbox and Google Drive thanks to cloud computing.

Users can back up their music, files, and images using cloud computing services, ensuring that they will always have access to them in the event of a hard drive accident.


a) What is an example of cloud computing?

We utilize cloud computing examples like emails, calendars, Skype, and WhatsApp every day. They make advantage of the cloud’s remote data accessibility function to support our data in the cloud architecture and enable anytime, anywhere access to them via the Internet.

b) Which four forms of cloud computing are there?

Private, public, hybrid, and multi-clouds are the four basic subtypes of cloud computing.
