AWS CloudFormation Custom Resources

This advanced feature allows you to embed custom logic (often via Lambda) directly into your CloudFormation templates. For DR, this means you can write a resource type that, when deployed, executes a specific, complex DR actionlike triggering a specific database failover sequence or updating a complex IAM rolethat standard resources cannot handle natively. It bridges the gap between pure IaC and custom automation.
