Description

An Aurora cluster in a Multi-AZ (availability zone) deployment provides enhanced availability and durability of data. When an Aurora cluster is provisioned, Amazon creates a primary DB instance and replicates the data to an Aurora replica in another availability zone.

How to fix?

Ensure that the aws_rds_cluster availability_zones field has more than one zone listed.

Example configuration:

resource "aws_rds_cluster" "example" {
  availability_zones = ["us-west-2a", "us-west-2b", "us-west-2c"]
  # other required fields here
}
