Software As a Service

Introduction

Introduction to SAAS

SaaS stands for Software as a Service. It is a software distribution model where a third-party provider hosts applications and makes them available to customers over the Internet. Instead of purchasing and installing software on their own devices, users access SaaS applications through a web browser or a dedicated app, typically on a subscription basis.

Software as a Service (SaaS) has transformed the way businesses access and utilize software applications. In the traditional model, companies would purchase, install, and maintain software on their own servers or computers.

However, with the advent of SaaS, software is now delivered over the internet, eliminating the need for users to handle installation, maintenance, and updates themselves.
