A cloud landing zone is the governed foundation where workloads are deployed. It establishes account structure, identity, networking, logging, security, policy, and cost ownership before every product team creates its own version.
The goal is not maximum central control. It is a safe, repeatable path that lets teams deploy without rebuilding foundational decisions.
Start With the Operating Model
Define who owns the cloud platform, security controls, network, identity, workload, cost, and incidents. Decide which controls are central, delegated, or shared.
Map business units, environments, legal entities, data classifications, regions, and regulatory boundaries. Account and subscription structure should express isolation and ownership, not the current organisation chart in excessive detail.
Design Account and Resource Hierarchy
Separate production from non-production and use multiple accounts or subscriptions to reduce blast radius. Establish organisational units, management groups, naming, tags, budgets, and ownership metadata.
Avoid one giant account and avoid creating hundreds of containers with no operating capability.
Establish Identity
Connect the corporate identity provider, require strong authentication, use role-based least privilege, separate administrative access, and provide emergency access with monitoring.
Prefer workload identity and short-lived credentials over embedded keys. Define joiner, mover, leaver, service-account, and access-review processes.
Build Network Foundations
Document connectivity, segmentation, ingress, egress, DNS, private endpoints, hybrid access, firewall policy, and inspection. Decide which services can use public endpoints and under what control.
Central networks can reduce inconsistency but also create bottlenecks. Provide standard patterns and clear exception routes.
Make Logging and Security Default
Enable central audit logs, configuration history, security findings, and network telemetry before workloads arrive. Protect log integrity and restrict access.
Deploy baseline encryption, key management, vulnerability controls, backup policy, threat detection, and incident contacts. Use policy as code to prevent or detect disallowed configurations.
Embed Cost Ownership
Require product, environment, team, and cost-centre metadata. Set budgets and anomaly alerts at useful boundaries. Define allocation for shared services.
Landing-zone design affects cost: network routing, log retention, duplicated security tools, and unused baseline capacity can become material.
Provide a Workload Onboarding Path
Offer versioned templates for accounts, networks, identity, CI/CD, observability, backup, and common service patterns. Include documentation, automated checks, and a support route.
Collect only the information needed to classify the workload and provision safely. A landing zone fails when teams bypass it because onboarding is slower than creating unmanaged infrastructure.
Test the Foundation
Validate denied access, emergency access, log delivery, policy enforcement, network failure, key rotation, backup restore, account vending, offboarding, incident investigation, and cost allocation.
Review the landing zone as the business grows. New regions, acquisitions, sensitive data, and product teams may change the required isolation.
