What each one is

The product in its own terms, so the numbers below have context.

Fission

Leader

Developers write short-lived functions that are triggered by HTTP requests or events, while the framework handles Kubernetes infrastructure management automatically. This eliminates the need to manually build containers or manage registries.

Independently observed

Google Cloud Functions

A platform for running small code snippets that respond to events, automatically scaling from zero to handle demand without requiring manual infrastructure provisioning or management. Charges only for actual execution time.
