Module 5: Terraform CI/CD Environments and Production Workflows on Azure

Tue, 23 Dec 2025 18:00:03 +1100

Overview Module 5 completes the Azure Terraform: From Zero to Production series by shifting focus from writing Terraform to operating Terraform safely in real-world Azure environments.

While HashiCorp Configuration Language (HCL) enables infrastructure definition, production readiness requires far more:

Strong separation between environments
Automated CI/CD delivery pipelines
Secure authentication
Change validation and policy enforcement
Resilience against failure and human error

By the end of this module, you move from:

“I can write Terraform”
to
“I can run Terraform in production with confidence.”
