FaaS — Function as a Service
Definition: A cloud model where you ship individual functions and the platform handles servers, scaling, and idle time. Pay-per-execution makes it brilliant for spiky workloads and brutal for steady ones.
Example
Moving the image-resize job to FaaS cut idle cost to near-zero — but the always-on API server stayed on a VM where it belonged.
When you'll hear it
FaaS shows up most often in engineering planning, architecture reviews, and sprint retrospectives. When someone uses it, they're usually referring to function as a service — and they expect the room to already know what that means.
