Which cloud service model provides software applications that can be accessed over the internet?

• A. IaaS
• B. PaaS
• C. SaaS
• D. CaaS

Answer: (C)

The main idea here is software delivered over the internet as a ready-to-use application. In this model, the provider hosts the software and takes care of the underlying infrastructure, runtime, and maintenance. You access the application through a web browser or similar client, without installing or managing the software on your own machines. This is exactly what Software as a Service offers: you use the software as a service, typically via subscription. Infrastructure as a Service provides raw compute, storage, and networking that you configure and manage, including the operating system and applications you install on it. Platform as a Service gives you a managed platform to develop and deploy your own apps, but you’re still responsible for developing and managing those applications. Container as a Service centers on deploying and orchestrating containers, focusing on infrastructure and runtime for containers rather than providing a standalone end-user software app. So the option that best matches software applications accessible over the internet is Software as a Service.
