- Terraform as Infrastructure as Code
- Terraform Configuration Files
- Version Control Integration
Overview
The exam tests Infrastructure as Code (IaC) and how Terraform fits into that paradigm. IaC is a fundamental shift from manual infrastructure provisioning, enabling automation, repeatability, and version control for your infrastructure definitions. Understanding this concept is critical for managing cloud resources effectively and consistently.
Core Concepts
- **Infrastructure as Code (IaC):** The practice of defining and managing infrastructure through code, enabling automation, version control, and repeatability.
- **Declarative vs. Imperative:** Terraform uses a declarative approach, specifying the desired state, while imperative approaches define the steps to achieve that state.
- **Terraform Configuration Files:** These files (typically `.tf` files) contain the definitions of your infrastructure resources, using a human-readable syntax.
Exam Tips
- Prioritize understanding the core concepts of IaC and Terraform's workflow over memorizing provider-specific details.
- Focus on the benefits of IaC, such as consistency, repeatability, and collaboration.
