Motivation

• Binary distribution

• Change set-based previews

• Synchronous interface

• Vanilla CloudFormation artefacts

AWS CLI	❎ Python package	❎ glue code	✅ aws cloudformation deploy
AWS SDK	✅ cross-language library	❎ glue code	❎ glue code
Serverless Framework	❎ JavaScript package	❎ no change sets	✅ serverless deploy
