OCI Landing Zone and Architecture Guide

How to design the compartments, identity model, network topology, and guardrails that every later OCI workload will inherit.

Structured server architecture representing an OCI landing zone
Summary

What this paper covers.

The landing zone is the part of an OCI estate that is cheapest to get right once and most expensive to fix later. It is the structure of compartments, the identity and access model, the network topology, the security controls, and the policy guardrails that every workload lands inside. Build it well and every later project inherits a sane foundation. Build it badly and you spend years retrofitting governance across a live estate.

This guide sets out how we design a landing zone that reflects how the organisation actually works, who owns what, who pays for what, and what must be isolated from what, and encodes those answers as structure rather than as documentation nobody reads.

Inside

What is inside.

  • How to model compartments around ownership, billing, and isolation.
  • An identity and access model that scales without becoming unmanageable.
  • Network topology choices and how they shape what is possible later.
  • The security controls and guardrails that belong in the foundation.
  • How the landing zone connects to other clouds and on premises.
  • Common landing zone mistakes and what they cost to undo.
Audience

Who it is for.

  • Architects designing or reviewing an OCI foundation.
  • Platform and cloud teams who will operate the estate day to day.
  • Security and compliance teams who need guardrails enforced, not remembered.
  • Leaders deciding how much foundation work to do before the first workload.
