FaaS
Function as a Service
Definition
FaaS is the execution model underlying serverless computing, where individual functions are the unit of deployment and billing. AWS Lambda, Google Cloud Functions, and Cloudflare Workers are leading FaaS platforms.
Functions are stateless, short-lived, and triggered by events (HTTP requests, queue messages, timer schedules). FaaS enables extreme granularity in scaling and cost but complicates observability and local development.
