Functions run as AWS Lambda behind Netlify's gateway

Routing handled automatically under `/functions/`

Environment variables and secrets injected at runtime

Functions scale automatically based on demand

Deployments tied to Netlify site builds

HTTP request sent to function endpoint

Netlify routes request to AWS Lambda

Handler function executes and returns response

Response delivered via HTTP to client

Metrics and logs collected by Netlify platform

Serverless functions as backend endpoints

Event-driven architecture for HTTP and cron triggers

Integration with static site frontend

Built on AWS Lambda managed by Netlify

CI/CD pipeline triggers deployments

JAMstack websites with dynamic features

Serverless form handling

Custom API endpoints for frontend apps

Webhook automation and integrations

Scheduled background tasks (cron)

Serverless endpoints for JAMstack apps

Simplified deployment and CI/CD integration

Automatic scaling and infrastructure management

Secure environment variables for secrets

Tight integration with static site builds

Automatic scaling handled by Netlify/AWS Lambda

No manual replication required

Monitor invocation metrics via Netlify dashboard

Use asynchronous functions for long tasks

Optimize function runtime and dependencies for performance

Move serverless functions from Netlify, Vercel, or AWS Lambda

Adapt code for Node.js or Go runtime

Ensure routes and environment variables are configured

Test functions locally with `netlify dev`
