Designing Terraform Modules That Stay Usable

A short example post about keeping Terraform modules focused, versioned, and easy to consume.

Modules should remove duplication around patterns that are already understood. They should not turn every resource into a hidden abstraction.

Good module boundaries

Start with one workflow or one platform capability. Keep the interface small enough that a reader can understand it without opening every internal file.

module "service_bucket" {
  source = "./modules/service-bucket"

  name        = "example-service"
  environment = "dev"
}
