A CloudOps team maintains a large CloudFormation template that provisions a standardized logging configuration (a CloudWatch log group, an IAM role, and a subscription filter) reused across dozens of separate application stacks. When they update the logging pattern, they must currently copy the revised resource definitions into every application template and redeploy each one. They want a way to define the logging pattern once, version it in a registry, and reference it as a reusable building block inside each application template so updates propagate through normal stack updates. Which approach best meets this requirement?
