What is Software as a Service (SaaS)?

Software as a Service (SaaS) refers to a cloud computing model in which software applications are delivered over the internet on a subscription basis. Instead of purchasing and installing software on local devices or servers, users access and use SaaS applications through web browsers. SaaS providers host and maintain the software, handle updates, and ensure availability and security. Common examples of SaaS applications include email services like Gmail, customer relationship management (CRM) software like Salesforce, and productivity suites like Microsoft 365. SaaS offers benefits such as scalability, cost-effectiveness, and ease of access from anywhere with an internet connection.
