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 — Identity Architecture

Covers identity architecture for the platform — identity providers, federation, authentication, and authorization models.

2 — Infrastructure IAM

Applies IAM to infrastructure provisioning — roles, permissions, least privilege, and service principals used by automation.

3 — Secrets Management

Covers secrets management for infrastructure — secret stores, key management, rotation policy, and encryption at rest/in transit.

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.
