Software as a Service (SaaS) is a cloud service model that delivers ready-to-use software over the internet. Users access the application through a web browser without installing or maintaining it.
Common SaaS applications include Gmail, Microsoft 365, Google Docs, and Salesforce. The cloud provider manages the software, infrastructure, updates, and security.
In simple words, SaaS lets you use software anytime, from anywhere, with only an internet connection.
