What is Software-as-a-Service (SaaS)?

Software-as-a-Service (SaaS) is a cloud-based software delivery model where applications are hosted by a service provider and made available to users over the internet. Instead of installing and maintaining software on individual computers or servers, users can access it via a web browser or app, typically through a subscription model.

Cloud-Based: No local installation; accessible from anywhere with an internet connection.
Subscription Model: Users pay monthly or annually, reducing upfront costs.
Automatic Updates: Software is maintained and updated by the provider.
Scalability: Easily adjustable to the number of users or features needed.

-Productivity tools (e.g., Microsoft 365, Google Workspace)
-Customer relationship management (CRM) systems (e.g., Salesforce)
-Communication platforms (e.g., Slack, Zoom)
-Enterprise resource planning (ERP) systems

-Reduces IT infrastructure and maintenance costs.
-Enables remote work and collaboration.
-Rapid deployment and easy scalability.

A company using Salesforce CRM via a web browser without installing any software on its computers is using SaaS.
