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.

1 — From Infrastructure Operations to Infrastructure Platforms

Traces how infrastructure management evolved from ticket-driven operations into a product built by a platform team for internal infrastructure consumers.

3 — Infrastructure Platform Architecture

Breaks an infrastructure platform into its control plane, execution plane, cloud provider integrations, interfaces, and lifecycle stages.

4 — Infrastructure Maturity Model

Maps the maturity curve from manual infrastructure through Infrastructure as Code and self-service to fully autonomous infrastructure.

2 — Designing Reusable Modules

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