Module: rds-replica

Terraform module to provision AWS RDS replica instances. These are best suited for reporting purposes.

IMPORTANT It is not possible to create a read replica for a DB Instance that belongs to an Aurora DB Cluster.

Introduction​

The module will create an RDS replica instance:

  • RDS Replica instance (MySQL, Postgres, SQL Server, Oracle)
  • RDS Subnet Group
  • RDS DB Security Group
  • DNS Record in Route53 for the DB endpoint

Usage​
