Managing infrastructure at scale requires discipline and structure. Terraform modules are the key to maintaining sanity in complex environments.
The Module Hierarchy
We organize our Terraform code into three layers: foundation modules, service modules, and environment configurations. Each layer has distinct responsibilities and constraints.
Versioning Strategy
Learn how to version your modules effectively to enable safe, incremental updates across your infrastructure.
Testing Terraform
Discover tools and techniques for testing your infrastructure code before it reaches production.
