## What it is
AWS Chalice is a Python serverless microframework for building and deploying applications on AWS Lambda. It provides a CLI for scaffolding and deployment, decorator-based integrations with API Gateway, S3, SNS, SQS, and scheduled tasks, plus automatic IAM policy generation.

## Use cases
- deploy a python rest api to aws lambda
- run a lambda function on a schedule
- trigger a lambda when a file is uploaded to s3
- process sqs queue messages with lambda
- quickly scaffold and deploy a serverless app
- generate iam policies automatically for my lambda app

## When to choose
- you want a lightweight, decorator-based alternative to the AWS SAM or Serverless Framework for Python
- you need fast iteration deploying Python APIs and event handlers to AWS Lambda
- you want automatic IAM policy generation from your code

## When to avoid
- you need multi-cloud or non-AWS serverless deployment
- you need complex infrastructure provisioning beyond Lambda, API Gateway, and event sources
- your team prefers infrastructure-as-code tools like Terraform or CDK for full control
