## What it is
Mangum is a Python adapter that runs ASGI applications (FastAPI, Starlette, Quart, Django, etc.) inside AWS Lambda. It translates API Gateway, ALB, Function URL, and Lambda@Edge events into ASGI requests and responses.

## Use cases
- deploy a fastapi app to aws lambda
- run asgi application on api gateway
- serve starlette app via lambda function url
- wrap django app for aws lambda handler
- handle alb and lambda@edge events with asgi app
- add gzip compression to api gateway responses

## When to choose
- you have an existing ASGI app and want to deploy it serverlessly on AWS Lambda
- you need API Gateway, ALB, Function URL, or Lambda@Edge event handling
- you want lifespan event support and binary media/compression in Lambda

## When to avoid
- you deploy on a traditional server or container rather than AWS Lambda
- you use a non-ASGI framework like Flask or WSGI apps
- you need other cloud providers' serverless platforms (e.g. Azure, GCP)
