What does SaaS stand for in cloud computing?

SaaS stands for Software as a Service, which is a cloud computing model that delivers software applications over the internet. In this model, software is hosted on cloud servers and provided to users on a subscription basis, eliminating the need for local installation or maintenance.

SaaS applications are typically accessed through a web browser, making them convenient and scalable for users, as updates and maintenance are handled by the service provider. This approach allows organizations to reduce IT overhead costs, improve collaboration, and provide access to applications from any device with an internet connection.

Understanding SaaS is fundamental in cloud computing because it represents one of the key service models alongside Infrastructure as a Service (IaaS) and Platform as a Service (PaaS). By knowing that SaaS pertains specifically to software delivery and user accessibility, one can better comprehend the broad spectrum of cloud solutions available today.
