What does SaaS stand for in cloud computing?

SaaS stands for Software as a Service. This model provides software applications over the internet, allowing users to access and use them through a web browser without needing to install or manage the software on their local devices. This approach enables businesses and individuals to utilize powerful software solutions while minimizing the burden of maintenance, updates, and infrastructure management.

In contrast, the other options refer to different concepts in cloud computing. System as a Service could imply the provisioning of an entire system, but it's not a standard term. Security as a Service pertains to cloud-based security solutions, while Storage as a Service focuses on the provision of cloud storage. These are distinct services and do not encompass the broad scope of software delivery that SaaS represents. Thus, understanding SaaS is crucial for recognizing how modern software applications are distributed and utilized in a cloud environment.
