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 — Networking Fundamentals

Covers cloud networking fundamentals — VPC/VNet design, subnetting, routing, and DNS as the base layer of the infrastructure platform.

3 — Connectivity

Covers hybrid and cross-cloud connectivity options — VPN, ExpressRoute, Direct Connect, PrivateLink, and service endpoints.

4 — Network Security

Covers network security controls for the platform — firewalls, NSGs/security groups, load balancers, WAF, and DDoS protection.

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.
