Production-ready, reusable Terraform module patterns for AWS, Azure and GCP that turn one-off infrastructure scripts into a maintainable component library. Each module follows the standard main/variables/outputs/versions layout with input validation, examples and Terratest coverage, so teams provision VPCs, databases and clusters the same way every time across clouds. Standardize your IaC instead of copy-pasting HCL between projects.

Copy-pasted Terraform is debt with a blast radius. The library approach scaffolds every module in a standard layout, validates inputs at plan time, splits state by domain, and refuses to ship anything Terratest has not proven.

No, the core of the library is the standard main/variables/outputs/versions layout, input validation and Terratest coverage, which pay off on a single cloud just as much. The included worked example is in fact an AWS VPC module wired into RDS; Azure and GCP are the same interface contract applied elsewhere.
Variable validation blocks reject bad input at plan time: CIDR regex checks, allowed-value lists and numeric bounds, and lifecycle guards like prevent_destroy protect stateful resources. Terratest then runs real apply/destroy cycles in CI, so what reaches production has been exercised.
No. You get the structure, the validation patterns, a complete VPC example, composition recipes and a Terratest scaffold: not a registry covering every AWS, Azure and GCP service. Modules beyond the examples you build yourself, following the same layout.
