How to Build a Well-Architected AWS Landing Zone
· via Gruntwork
Summary: The landing zone is the highest-leverage early decision in AWS, since accounts, identity, networking and guardrails all inherit it. The guide compares the build routes honestly (Control Tower, Landing Zone Accelerator, account factory, fully custom), each trading flexibility against maintenance differently. OU design and account vending hurt most to change later, so spend your thinking there first and manage the landing zone itself with IaC from day one.
Who should read it: anyone standing up multi-account AWS from scratch, or re-platforming an organisation that grew one account at a time.
