Infrastructure Platform Engineering

A book-shaped table of contents for infrastructure platform engineering: from infrastructure operations to self-service platforms, IaC foundations, Terraform/OpenTofu, cloud platform design, networking, identity, compute, storage, golden images, automation, governance, observability, reliability, enterprise platforms, anti-patterns, and MAANG interview prep — cross-linking existing sre/networks/kubernetes/patterns/internal-developer-platforms notes instead of duplicating them.

2 — Designing Reusable Modules

Covers designing reusable Terraform/OpenTofu modules — structure, inputs/outputs, composition, and registry distribution.

3 — Enterprise Module Design

Extends module design to enterprise scale — versioning strategy, automated testing, documentation, and publishing workflows.

5 — Policy & Validation

Adds policy and validation gates to infrastructure pipelines — variable validation, static analysis, security scanning, and cost estimation.

1 — Terraform/OpenTofu Architecture

Explains Terraform/OpenTofu's core architecture — providers, resources, modules, and workspaces — as the building blocks of a platform's IaC layer.
