How to configure vpc for a lambda and dynamodb?

I'm creating a VPC in aws, and plan to add dynamodb and lambda to access to dynamo. If dynamodb is in a private subnet, what else do i need for lambda to connect to the dynamo. If lambda is invoked by API gateway , can lambda and dynamodb be under same private subnet?

DynamoDB is not located in your VPC. If you want to access DynamoDB via the private network from Lambda, you can use the DynamoDB VPC Gateway endpoint. A route will be added to your subnet route table, all traffic to DynamoDB will route through AWS internal network.

Things to setup:

  1. Private subnet
  2. DynamoDB VPC endpoint (Gateway type, use interface type (cost $) if you want to connect via private IP)
  3. VPC Lambda
  4. If you want the API Gateway also be private, setup private API Gateway and API Gateway VPC endpoint
