Google Cloud Functions is now Cloud Run functions: what it is, and what it really costs
Google Cloud Functions is Google's serverless functions product, renamed Cloud Run functions in August 2024 and folded into the Cloud Run platform. You write event-driven code, Google runs it, and you pay per request, per vCPU-second, and per GiB-second after a free tier of 2 million requests a month. The catch: per-invocation billing scales your mistakes exactly as efficiently as it scales your product.
