Terraform modules are reusable, composable packages of Terraform configuration that define infrastructure resources in a standardised way. They enable teams to encapsulate best practices and reuse infrastructure patterns across environments. Also known as IaC modules, they are foundational to scalable Infrastructure as Code.
Without modules, Terraform configurations quickly become duplicated, inconsistent, and hard to maintain. Terraform modules improve reliability, reduce errors, and allow infrastructure teams to scale provisioning practices across teams and environments.
Modules are defined in separate directories or registries and referenced from Terraform configurations. Inputs control behavior, while outputs expose useful information. Versioning ensures controlled evolution and safe reuse.
BuildPiper integrates Terraform modules into environment and platform workflows, enabling teams to provision infrastructure using governed, reusable patterns. This ensures environments are created consistently and securely across the organisation.
No, but they are strongly recommended for any non-trivial infrastructure to improve reuse, consistency, and maintainability.
Yes. Modules can be versioned to control changes and ensure stability across environments.
BuildPiper uses Terraform modules as part of environment automation, enabling standardised and policy-compliant infrastructure provisioning.
