RDS Setup

We're going to start setting up the infrastructure on the new VPC starting with the database.

Subnet Group

When we setup a database in RDS, we specify a subnet group instead of just a single subnet. This is so RDS can place and replicate the database within a pre defined selection of subnets instead of just being limited to one.

We're going to start by setting up a custom subnet group for RDS that tells it to use either of the private db subnets for our database.

step 1:

In the RDS console, click on Subnet groups

step 2:

Click on Create DB subnet group

step 3:

Give it a name, description, and select the qr app vpc

step 4:

Select both of the db subnets

You should only have the two db subnets selected, one on each az

step 5:

Remove the AZs that you don't have subnets setup in

It should end up looking something like this

step 6:

Click on Create

Database

step 7:

In the RDS console, click on Create database
