Welcome to this Infrastructure as Code lesson.
1Core Concepts
This module covers the essential Terraform concepts.
2Step-by-Step Breakdown
Terraform is split into two main blocks: Terraform Core (which handles the logic) and Providers (which handle the communication with specific APIs). Pro Tip: Core is the brain; Providers are the hands.
Terraform keeps track of the 'Real World' in a JSON file called the State. It uses this to know what it has created and what needs to change. Pro Tip: State is the 'Truth' of your infrastructure.
Terraform automatically builds a Dependency Graph. It knows that a VPC must be created BEFORE an EC2 instance can be placed inside it. Pro Tip: Terraform handles the 'order of operations' so you don't have to.
