Part I

Infrastructure as Code Foundations

6 checks

Why Infrastructure as Code ExistsThe operational pain that motivated IaC, the four provisioning approaches, why IaC won, and the production defaults that follow from disciplined adoption.→
Declarative versus Imperative ProvisioningThe declarative model Terraform implements, the imperative escapes it exposes, and the cost of imperative thinking inside a declarative tool.→
Terraform in the Infrastructure EcosystemWhere Terraform sits among OpenTofu, Pulumi, Crossplane, Ansible, and vendor-managed IaC, and how to pick the right tool for a given constraint.→
Reproducibility and the BlueprintThe first principle of IaC reproducibility — same code, same state backend, same provider versions produce the same plan — and the constraints that protect it.→
Drift: The Tax of Manual InfrastructureConfiguration drift at the IaC level, why it is dangerous, why it is normal, and the three dispositions that keep drift from becoming an outage.→
Infrastructure Ownership and the Configuration RepositoryWho owns IaC, the boundary between the platform team and the application team, how CODEOWNERS encodes ownership, and the cost of ambiguous ownership.→
