AWS Lambda
AWS Lambda runs functions on demand without managing servers, scaling to zero and billing per invocation.
At a glance
AWS Lambda runs functions on demand without managing servers, scaling to zero and billing per invocation.
Catalog categories: serverless.
Catalogued capability areas: - Event-driven function execution - Automatic scaling and scale-to-zero - Managed runtimes and triggers
This summary reflects the catalog record, not a complete product specification. Verify intended users, end-to-end workflows, supported platforms, edge cases, data handling, and constraints against cited sources. Treat capability labels as research leads until that verification is complete.
- Event-driven function execution
- Automatic scaling and scale-to-zero
- Managed runtimes and triggers
Open-source alternative
4 candidate projects in the landscape. A candidate may cover all, part, or none of what AWS Lambda does — read the coverage and gaps below.
OpenFaaS
MITServerless functions on Kubernetes/Docker.
Community edition is open source.
Knative
Apache-2.0Serverless serving and eventing on Kubernetes.
CNCF project.
Apache OpenWhisk
Apache-2.0Event-driven FaaS platform.
The original open FaaS.
Fission / Nuclio
Apache-2.0Kubernetes-native FaaS with fast cold starts.
Alternative runtimes.
Coverage and gaps
Alternative coverage
Available. Multiple mature open serverless platforms exist.
The gap
AWS’s managed integrations (IAM, event sources, edge) and per-invocation economics differ.
Build this product with your agent
This Markdown file is the coding-agent skill for AWS Lambda. Give it to your agent in your project; it guides research, reuse decisions, implementation and verification.
