Which of the following is usually accessed via a web browser?

The correct answer is Software as a Service (SaaS). SaaS applications are typically accessed via a web browser, allowing users to access software solutions over the internet without the need for local installation. This model promotes ease of use, as users can simply log in to a web interface to access the application from any device with internet connectivity.

In contrast, Infrastructure as a Service (IaaS) primarily focuses on the provisioning of virtualized computing resources over the internet. While the management interfaces for IaaS may be web-based, the actual services (like virtual machines and storage) are not accessed directly through a browser but rather through APIs or management consoles.

Platform as a Service (PaaS) provides a platform allowing developers to build, test, and deploy applications over the internet. While PaaS offerings may include some web-based tools, the core functionality is intended for software development, rather than direct usage by end-users through a browser.

Virtual machines represent computing environments that can be created and run on a server. Although tools for managing them can be accessed via a browser, virtual machines themselves are not applications that users would typically access directly through a web interface; they require remote desktop protocols or similar technologies for access.

Thus, SaaS stands
