There is currently a bug with the CDK using Event Notifications (aws/aws-cdk#5760). See Custom Resource workaround in "service-a-stateless.ts".

This demo can be extended to perform cross-account replicaiton.

However to keep things simple, we deploy 3 services each with their own Cloudformation Stack to demonstrate the replication.

Service A is the master source of the data. Services B and C use the source data with synchronisation with Service A.

Service A will cleanse and validate the data so even if the actor uploads a corrupted copy then it won't break downstream services.

This is a blank project for CDK development with TypeScript.

The cdk.json file tells the CDK Toolkit how to execute your app.

• npm run build compile typescript to js
• npm run watch watch for changes and compile
• npm run test perform the jest unit tests
• cdk deploy deploy this stack to your default AWS account/region
• cdk diff compare deployed stack with current state
• cdk synth emits the synthesized CloudFormation template
