What describes a way of delivering applications remotely over the internet instead of locally on machines?

• A. Platform as a Service (PaaS)
• B. Application Streaming
• C. Software as a Service (SaaS)
• D. Infrastructure as a Service (IaaS)

Answer: (C)

Delivering applications remotely over the internet as a service means you access the software via a web-based interface rather than installing it on your own device. This is Software as a Service. The vendor hosts the application, handles maintenance, security, and updates, and you typically pay a subscription to use it. You can use it from various devices through a browser or lightweight client, with little to no local installation.

This differs from platform as a service, which provides a environment to develop and run your own applications rather than offering a ready-made app for end users. It also differs from infrastructure as a service, which gives you virtualized computing resources to deploy and manage your own software. Application streaming exists as a way to run apps remotely and send the UI to the local device, but SaaS is the standard model for delivering ready-made software over the internet.
