What is Cloud Computing?

Ans: Let me describe Cloud Computing in details so that you can have a clear understanding.I believe most of us have heard the name ‘CLOUD COMPUTING’.But what does it mean?

First of all, why the name is so?

Let me describe in simple words.

The name ‘CLOUD’ has no relation with the internal technology used. And it does not have any relation with the computing area also.The name ‘CLOUD’ has come from the ‘CLOUD-SHAPED’ symbol used to represent abstraction/abstract layer around the software/hardware/infrastructure or any other service (known as services provided by the cloud).If you check any picture of cloud computing, you will found the CLOUD shaped diagram and everything is kept inside it.

The basic idea of cloud computing is, keep everything as SERVICE and use it when ever you need.

Users can access cloud-based applications through a web browser or a light-weight desktop or mobile app while the business software and user’s data are stored on servers at a remote location.

Cloud computing allows enterprises to get their applications up and running faster with improved manageability and less maintenance. It gives the flexibility to rapidly adjust resources to meet fluctuating and unpredictable business demand.

There are many types of public cloud computing like

a) Infrastructure as a service (IaaS)
b) Platform as a service (PaaS)
c) Software as a service (SaaS)
d) Storage as a service (STaaS)
e) Security as a service (SECaaS)
f) Data as a service (DaaS)
g) Test environment as a service (TEaaS)
h) Desktop as a service (DaaS)
i) API as a service (APIaaS)
