What IaC is and the problem it solves
Infrastructure as Code (IaC) is the practice of managing and provisioning infrastructure (servers, networks, databases, etc.) using code instead of manual processes.
It solves several key problems:
Manual errors → reduces human mistakes from repetitive tasks
Inconsistency (configuration drift) → ensures all environments are identical
Slow deployments → enables fast, automated provisioning
The difference between declarative and imperative approaches
Imperative approach
You define how to achieve a result step by step.
Example: install packages, configure files, start services manually in sequence.
Declarative approach
You define what the final desired state should be, and the tool figures out how to achieve it.
Why Terraform is worth learning
Terraform is worth learning because:
It allows you to manage infrastructure across multiple cloud providers (AWS, Azure, GCP, etc.)
It uses a simple declarative language, making it easier to understand and maintain
It enables automation and scalability, which are essential in DevOps
It integrates well with modern tools like CI/CD, Docker, and Kubernetes
It is widely adopted and in high demand in the industry
