Considerations
- For apps that may not see traffic for several minutes at a time, you could see cold starts
- Cannot use native libraries (aka Addons) unless you package your app on an EC2 machine running Amazon Linux
- Stateless only
- API Gateway has a timeout of 29 seconds, and Lambda has a maximum execution time of 15 minutes.
