What each one is

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

AWS Lambda

Leader

A serverless compute service that automatically scales in response to demand and reduces to zero during idle periods. Execute code triggered by events from AWS services and external applications with built-in security, monitoring, and support for multiple programming languages.

Independently observed

Fission

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.
