Welcome to this Infrastructure as Code lesson.
1Core Concepts
This module covers the essential Terraform concepts.
2Step-by-Step Breakdown
Modules use input variables to allow customization. Think of these as the arguments passed to a function. They define what data the module needs to operate. Pro Tip: Inputs allow the same module to be used for Dev, Stage, and Prod.
Outputs allow a module to return information to the calling configuration. This is how you share data, like a VPC ID, with other modules. Pro Tip: Outputs are the 'Return Values' that link infrastructure layers together.
Resources inside a module are scoped to that module instance. You can call the same module multiple times to create multiple independent copies of the stack. Pro Tip: Module scoping prevents resource naming collisions.
