This article focuses on best practices for managing Infrastructure as Code (IaC) with Terraform.
It suggests:
- Using remote state,
- Using existing shared and community modules,
- Avoiding hardcoded variables,
- Consistently formatting and validating code,
- Using a naming convention,
- Tagging resources,
- Introducing policy as code,
- Implementing a secrets management strategy,
- Testing code,
- Taking advantage of IDE extensions.
The article also describes key Terraform concepts such as Terraform Configuration Language, Resources, Data Sources, Modules, State, and Providers. It provides guidance on how to structure Terraform projects based on the size of the infrastructure, ownership and responsibility, rate of change, and ease of management.
The authors of this article emphasize a need for using version control, applying a collaborative approach in IaC, segmenting infrastructure environments, and minimizing risk for improved clarity, environment isolation, and scalability.
