# OVERVIEW **What It Does:** Terraform modules allow users to create, reuse, and manage infrastructure configurations efficiently by encapsulating resources and making architecture recommendations. **Why People Use It:** Users leverage Terraform modules for scalable, reusable, and composable infrastructure management, facilitating collaboration and standardization in infrastructure deployment. [[Understanding the Value of Terraform Modules]] # HOW TO USE IT **Most Common Syntax:** Modules are often called in a Terraform configuration using the `module` block, usually referencing a source like a GitHub URL or the Terraform Registry. ```hcl module "example" { source = "path/to/module/source" # Additional module arguments } ``` # COMMON USE CASES - **Creating Reusable Infrastructure:** Using modules for standard configurations across different environments. - **Self-Service Infrastructure Provisioning:** Allowing users to provision infrastructure through pre-configured modules. - **Managing Complex Configurations:** Breaking down complex setups into manageable sub-modules for clarity and reusability. - **Version Control:** Utilizing versioned modules from Terraform Registry for predictable deployments. # RESOURCES [Modules overview | Terraform | HashiCorp Developer](https://developer.hashicorp.com/terraform/tutorials/modules/module)
