What is Cloud Computing?

Cloud computing is defined as Internet-based services that are used to store, manage, and process data on an internet server rather than a local server or personal system.

There are basically 3 categories in cloud computing:
 

Below-listed three service categories are found in cloud computing:

A). SaaS (Software as a Service

SaaS is a short form of software as a service that allows companies to use or install the software without purchasing them. In this way, the expenditure is reduced drastically as they do not need to install them on their system and can use them directly from cloud servers.

B). PaaS (Platform as a Service)

Developers can build and collaborate applications and projects without maintaining or purchasing the infrastructure

C). IaaS (Infrastructure as a Service)

C). Cost-Efficient

It is quite a time consuming and costly affair to install and manage own servers, as you may have to install many software programs and configure them on your own server. However, in the case of cloud computing, you need not maintain, update, and install a separate server you can use the existing cloud servers and access its services as well.
