Route tables in AWS

resolving routing between VPCs and serverless things like DynamoDB

First, added to serverless.ts to create vpc endpoint

VPCEndpointForDynamo: {
  Type: "AWS::EC2::VPCEndpoint",
  Properties: {
    ServiceName: `com.amazonaws.${region}.dynamodb`,
    VpcEndpointType: "Gateway",
    VpcId: vpcId
  },
}

then:

• manually added route tables from the VPC → Endpoint console
• go to Route Tables console to find routes → destination pl-xxxx destination
• added it to the Security Group outbound rules using the pl-xxxxxxx destination
