The hands-on lab is part of this learning path
Ready for the real environment experience?
Modules are a critical component of production-grade Terraform configurations. It gives infrastructure developers the ability to split infrastructure services up into separate components. For example, you can have a module for deploying Virtual Machines and a module for Virtual Networks. You can then use each module as a building block for creating entire environments in Azure.
Terraform configuration files that are thousands of lines of code are considered an anti-pattern. Infrastructure code becomes unmanageable, and execution plans can take over 10 minutes to create. Instead, split the code up into modules. Modules separate pieces of the infrastructure into reusable, testable units.
Modules also provide a way for the community to share Terraform configurations with others. There are hundreds of modules on the Terraform Registry. It is highly recommended to look at the community-made modules before creating your own from scratch. The State of DevOps report shows that companies that re-use code are high performers.
In this lab, you will learn how to create reusable Terraform configurations using modules.
Upon completion of this lab you will be able to:
- Understand how to use modules to create reusable infrastructure
- Know the benefits of using modules
- Learn how to pass data between modules
