Deploying Amazon RDS for Db2 using Terraform

This article presents a modular Terraform template for deploying Amazon RDS for Db2 instances with infrastructure-as-code best practices.

• Seven numbered Terraform modules handle backend, networking, IAM, KMS, parameters, RDS, and License Manager
• Template provisions complete RDS for Db2 setup in under one hour from empty AWS account
• Each module maintains separate remote state using S3, DynamoDB, and KMS for isolation
• Supports AWS commercial and GovCloud regions with partition-aware ARN construction
• Auto-resolves latest minor versions and generates instance identifiers from configuration
• Integrates AWS License Manager for BYOL vCPU consumption tracking
• Includes convenience features like RDS-managed master passwords in AWS Secrets Manager
• Modules are idempotent and can be adopted incrementally or reuse existing resources

The template provides production-grade RDS for Db2 provisioning with built-in state management, encryption, monitoring, and licensing integration.
