AWS Lambda DynamoDB Demo

This application demos basic operations on DynamoDB from AWS Lambda, using AWS JavaScript SDK.

Notes

• DynamoDB does not support resource policies — https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/access-control-overview.html#access-control-manage-access-resource-based
• Policies property of AWS::Serverless::Function also allows SAM policy templates — https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/serverless-policy-templates.html

Appendix

• Deployment Notes: How to deploy and test this application.
• VPC endpoint routing test: A log file demonstrating Lambda error when the functions are associated with private subnet and the DynamoDB VPC endpoint is removed.
