What is Cloud Computing? Explained in Simple Words

Nowadays the world of internet is changing very fast. Earlier we used to keep all the data and software in our computer, mobile or laptop. But now you can store data, run apps and use servers from your phone or computer while sitting in any corner of the world. This is Cloud Computing .

Many people hear this name but do not understand what it is. In this blog we will understand Cloud Computing in easy Hindi and know how it works, what are its advantages and disadvantages, and why it is important for us.

What is Cloud Computing?

In simple terms, Cloud Computing means using servers, storage, and software over the Internet without having to keep them on your computer.

This means that you do not need to keep your data or programs on your computer. You can store and use your data, files or applications on another company's server (computer) via the Internet.

For example, you must have heard the names of Google Drive, Dropbox, iCloud. All these are cloud services. In these, your data is not stored on your computer but is kept safe in the big data centers (servers) of companies and you can use it from the internet whenever and wherever you want.

How does Cloud Computing work?

Cloud Computing consists of large data centers that have thousands of computers and servers. These data centers are located at different places around the world.

When you save a file in the Cloud, it is actually saved on the servers of these data centers.
When you open that file, it comes to your device via the Internet.
That is, you remain connected to the servers through the Internet, where your files and apps are stored.

Types of Cloud Computing

There are mainly three types of Cloud Computing –

  1. IaaS (Infrastructure as a Service)
    In this, companies rent their server, storage and network to you. You do not need to buy hardware. For example - Amazon Web Services (AWS), Google Cloud Platform.

  2. PaaS (Platform as a Service)
    In this, companies provide you a platform on which you can develop your software or app. There is no hassle of hardware and software. Like - Microsoft Azure, Google App Engine.

  3. SaaS (Software as a Service)
    In this, companies directly provide you software which you can use from the internet. Such as Gmail, Google Drive, Zoom, Dropbox.
