I've looked at chalice very shortly, and it was really nice to easily set up an API Gateway -> Lambda connection, we haven't really looked at it for our non api-gateway uses.
Tangentially related question. What deployment tools are people using to manage systems with many lambda functions?
We use SWF to trigger over 50 separate lambda functions in processing. We've got some very nice internally developed tools to identify which functions are out of date and help with deployment. I'm just curious what else is available to handle DevOps tasks in a Serverless environment (i.e. deploying library updates, etc).
