Terraform module to provision AWS RDS
instances
This project is part of our comprehensive "SweetOps" approach towards DevOps.
It's 100% Open Source and licensed under the APACHE2.
The module will create:
- DB instance (MySQL, Postgres, SQL Server, Oracle)
- DB Parameter Group
- DB Subnet Group
- DB Security Group
- DNS Record in Route53 for the DB endpoint
