How Serverless Pricing Works

Serverless functions are billed based on the number of invocations and the compute resources consumed during execution.

AWS Lambda & Azure Functions: Charge per request ($0.20/million) plus per GB-second of compute time.

GCP Cloud Functions: Charges separately for invocations ($0.40/million), CPU time (per GHz-second), memory (per GB-second), and network egress.

All providers offer a generous free tier: Lambda includes 1M requests and 400,000 GB-seconds per month.
