A decision guide for teams choosing an operating model—not a feature-count contest. Validate current limits and pricing in the linked product documentation before committing.
01 / Short answer
AWS Lambda: AWS workloads triggered by events or requests that fit function constraints.
Netlify Functions: Web teams wanting backend functions deployed with a Netlify site.
02 / Decision matrix
| Criterion | AWS Lambda | Netlify Functions |
|---|---|---|
| Operating model | AWS event-driven functions runtime with provider-managed infrastructure. | Functions integrated with Netlify web deployment and edge delivery workflows. |
| Best fit | AWS workloads triggered by events or requests that fit function constraints. | Web teams wanting backend functions deployed with a Netlify site. |
| Main trade-off | Runtime, duration, concurrency and provider coupling shape architecture. | Runtime limits and platform coupling should be tested for backend-heavy systems. |
| Pricing basis | Requests, duration and supporting services | Invocations, compute and Netlify plan |
| Portability lens | Most value comes from its own platform integration; price migration explicitly. | Most value comes from its own platform integration; price migration explicitly. |
03 / Selection test
The test should include deployment, identity, telemetry, failure recovery and one real policy requirement. A happy-path deployment cannot expose day-two cost.
Test this with one representative workload and record the operational owner, failure path and exit cost.

Name which system owns identity, deployment, policy, telemetry and recovery. If both appear to own the same decision, simplify.
