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 — Copy-Paste Infrastructure

Covers copy-paste infrastructure — duplicated, drifted configuration instead of shared modules — and its long-term cost.

3 — Module Sprawl

Covers module sprawl — uncontrolled proliferation of near-duplicate Terraform/OpenTofu modules — and how it erodes reuse.

4 — Infrastructure Drift

Covers infrastructure drift — divergence between declared and actual state — and why it undermines platform guarantees.

5 — Shared Cloud Accounts

Covers the shared-cloud-account anti-pattern — blast-radius and blame-attribution problems from unsegmented accounts.
