Certificate of Cloud Security Knowledge (CCSK) 2025 – 400 Free Practice Questions to Pass the Exam

The term that refers to a cloud service where users can interact primarily through web interfaces is Software as a Service (SaaS). SaaS delivers software applications over the internet, allowing users to access and use the software through a web browser without needing to install or manage the underlying infrastructure or application software. This model enhances accessibility and convenience, as users can log in from any device with internet connectivity, making it easy to collaborate and share applications.

In contrast, Platform as a Service (PaaS) focuses on providing a framework for developers to create and manage applications without handling the infrastructure, while Infrastructure as a Service (IaaS) provides virtualized computing resources over the internet. Function as a Service (FaaS) involves serverless computing, where code is executed in response to events, but it does not typically involve a user interface designed for user interaction like a SaaS application does.
