GCP Cloud Functions
ELI5 — The Vibe Check
Cloud Functions is Google's serverless compute — write a function, deploy it, and Google handles everything else. No servers, no scaling decisions, no midnight pages about container health. It just runs when triggered. It's like AWS Lambda but with that distinctly Google 'we might deprecate this' energy.
Real Talk
Google Cloud Functions is an event-driven serverless compute platform that runs single-purpose functions in response to cloud events. It supports Node.js, Python, Go, Java, .NET, Ruby, and PHP runtimes. Gen 2 is built on Cloud Run and offers longer timeouts, larger instances, and concurrency support.
When You'll Hear This
"We use Cloud Functions for all our webhook handlers." / "Cloud Functions Gen 2 finally supports concurrency — one instance handles multiple requests."

FaaS (Function as a Service)
FaaS is when you write a tiny function and deploy it to the cloud, and it only runs (and charges you) when someone calls it.
Serverless
Serverless doesn't mean there are no servers — it means YOU don't have to think about servers. Someone else manages them, scales them, and patches them.
