Answer

The `vpc-app` module creates three subnet tiers: - `public` - `private-app` - `private-persistence` What are the differences between the three? In particular, what is the difference between `private-app` and `private-persistence`?

The difference and purpose of the subnet tiers are explained in the `terraform-aws-vpc` [README](https://github.com/gruntwork-io/terraform-aws-vpc/tree/master/modules/vpc-app#three-subnet-tiers)
