Cloud computing is where software applications, data storage, and processing capacity are accessed over the Internet. There are three ways to cloud compute.

The three building blocks of Cloud Computing are: SaaS (Software as a Service), PaaS (Platform as a Service), and IaaS (Infrastructure as a Service). All of these allow users to run applications or store data online. However, each offers a different level of user flexibility and control.

In basic terms, SaaS is a business model that allows existing online applications to run on the cloud.

On the other hand, PaaS allows users to create their own cloud applications using supplier-specific tools and languages.

And IaaS allows users to run any applications they please on their choice of cloud hardware.

This explanation is an initial overview. We’ll get deeper into each layer of cloud computing in our upcoming posts.

But it’s good to know that there are three reasons why Cloud hosting is becoming so popular:

  • Scalability: Cloud is easy to grow or shrink according to the user’s demand.
  • Immediacy: The computing power is there when needed—the user can turn it on or off.
  • Affordability: Users pay only for what they use.

And finally, do you already work with cloud? What kind of block are you using? Do you see the benefits?
