Software as a Service (SaaS): Cloud-Hosted Applications & Business Solutions

Introduction to Software as a Service (SaaS)

Software as a Service (SaaS) is a cloud computing model that delivers fully managed applications over the internet. Users can access SaaS applications through a web browser without needing to install or maintain software on their devices. SaaS solutions power a wide range of business operations, including email, customer relationship management (CRM), collaboration tools, and enterprise applications.

Key Benefits of SaaS:

Provides automatic updates and security patches.
Offers pay-as-you-go pricing for cost efficiency.
Enables remote access from any device with an internet connection.
