The infrastructure provisioned also includes an Aurora RDS instance. Navigate to RDS in the console and select “Databases” from the navigation pane on the left-hand side of the console. Here, you’ll see the LAB1 instance that has been provisioned. The screen will appear as follows:
This database is deployed with separate reader and writer instances. As our monolith database, it will hold all of the data for our entire single-tenant environment. The code in our application services have access to any of the data in database, enabling them to couple to any and all of the constructs in this database.
