## What it is
Zappa is a Python tool for deploying WSGI applications (Flask, Django, Pyramid, Bottle) as serverless web services on AWS Lambda and API Gateway. It provides a CLI for deploying, updating, rolling back, scheduling events, and running asynchronous tasks on AWS.

## Use cases
- deploy a flask app to aws lambda
- host django on serverless aws
- run python web services without managing servers
- schedule cron jobs on aws lambda
- run async background tasks in lambda
- serve a wsgi app through api gateway

## When to choose
- you have an existing Python WSGI app (Flask/Django) you want on Lambda
- you want cheap, auto-scaling hosting for Python APIs on AWS
- you need Lambda-based scheduled or asynchronous tasks

## When to avoid
- you use ASGI apps like FastAPI (use Mangum or similar instead)
- you need long-running requests beyond Lambda timeouts
- you target clouds other than AWS
