Architectural Track // Modern Infra 01

Terraform Provisioning

Tagline: Infrastructure as Code Logic.

Moving from manual configuration to deterministic code. Focus: HCL (HashiCorp Configuration Language), state management, and multi-cloud provider architecture.

Declarative Logic

Level 100: HCL Foundation

  • Resources & Data: Defining the desired state of infrastructure.
  • Variables & Outputs: Parameterizing deployments for modularity.
  • Provider Logic: Connecting to AWS, Azure, GCP, and vSphere.

Architect’s Verdict: Terraform is about the “What,” not the “How.” Declarative code ensures your environment is reproducible.

Persistence

Level 200: State Strategy

  • Remote State: Using S3 or Terraform Cloud for team collaboration.
  • State Locking: Preventing concurrent modifications and corruption.
  • Workspaces: Managing multiple environments (Dev/Test/Prod).

Architect’s Verdict: The State file is the source of truth. Lose the state, and you lose your map to the infrastructure.

Scale

Level 300: Terraform Modules

  • Reusable Modules: Standardizing infrastructure patterns across the org.
  • Terragrunt: Keeping your Terraform configurations DRY.
  • Policy as Code: Using Sentinel or OPA to enforce security guardrails.

Architect’s Verdict: Modules turn Terraform into a factory. Build once, deploy everywhere with consistency.
