Which cloud service model delivers software applications over the internet and is accessed via a web browser?

• A. Desktop as a Service
• B. Software as a Service
• C. Platform as a Service
• D. Infrastructure as a Service

Answer: (B)

Software as a Service delivers software applications over the internet and is accessed through a web browser. In this model, the provider hosts the application, takes care of updates, security, and maintenance, and you simply use the software online without installing anything on your device. This is why you can open a browser, sign in, and start using the app right away. This differs from other cloud service models that focus on providing spaces to run or build things rather than the software itself. The other models involve closer control of the environment: one gives you a remote desktop experience, another provides a platform for developing and deploying applications, and the last offers virtual hardware and infrastructure to manage. The key trait of the scenario—software hosted and accessed via a browser—points to Software as a Service.
