Cloud architecture & landing zones · Burlington, Ontario
Cloud Architecture and Landing Zones
A landing zone is the governed foundation a cloud environment is built on — subscription structure, network topology, identity and policy guardrails set out before workloads arrive, following Well-Architected and Cloud Adoption Framework principles.
What this covers
- Subscription and management group hierarchy defined upfront
- Network topology designed for growth and segmentation
- Policy-as-code guardrails enforced automatically
- Identity foundation aligned to least privilege
- Reference architecture documented for future workloads
01Why landing zones matter
The foundation decides how the environment ages
An environment without a landing zone still works on day one. The problems appear at month twelve, when naming is inconsistent, access is over-permissioned, and nobody can explain the network layout.
A landing zone establishes management group hierarchy, subscription boundaries, naming and tagging standards, network segmentation, and identity foundations before the first production workload deploys. Azure Policy or equivalent guardrails enforce these standards automatically, so compliance does not depend on every engineer remembering the rules.
Network design follows a hub-and-spoke or equivalent topology appropriate to your scale, with segmentation between production, development and management traffic. This limits the blast radius of a misconfiguration or compromised workload and gives a clear place to apply firewall and monitoring controls.
The result is a reference architecture your organization can extend for the next workload without re-deciding fundamentals each time — a deliberate application of ISO/IEC 27001 Annex A's expectations around secure system architecture and segregation.
02Landing zone components
What a landing zone establishes
Foundational decisions made once and enforced consistently.
- Management group and subscription hierarchy
- Naming, tagging and resource organization standards
- Hub-and-spoke or virtual WAN network topology
- Network segmentation and firewall policy
- Identity and role-based access foundations
- Policy-as-code guardrails and compliance baselines
- Centralized logging and monitoring architecture
- Shared services (DNS, identity, backup)
- Cost management and budget structure
- Disaster recovery and region strategy
- CI/CD and infrastructure-as-code integration points
- Documentation and reference architecture handover
03Design principles applied
How landing zones are designed
Structured against the pillars of the Well-Architected Framework.
Reliability
Region and availability zone strategy is chosen based on your recovery objectives, not defaulted to a single location.
Security
Segmentation, least-privilege identity and centralized logging are built in from the first subscription, aligned to NIST CSF Protect and Detect functions.
Cost optimization
Subscription structure supports cost allocation by department or workload, so spend is visible and attributable from day one.
Operational excellence
Infrastructure-as-code templates capture the landing zone definition, so it can be audited, versioned and redeployed rather than existing only as manual configuration.
Performance efficiency
Network and resource placement account for latency between workloads and users, including hybrid connectivity to your Burlington sites.
Governed extensibility
New subscriptions and workloads inherit the landing zone's policy and network baseline automatically, rather than needing to be reconfigured individually.
FAQCommon questions
Questions Burlington organizations ask
Do we need a landing zone if we only run a few cloud servers?
A lightweight version still pays off — consistent naming, basic segmentation and policy guardrails prevent the ad hoc sprawl that makes small environments hard to secure and expensive to unwind later.
Can a landing zone be applied to an existing cloud environment?
Yes, though it typically involves a remediation phase to bring existing resources into the new structure. This is planned as a controlled project rather than a disruptive one-time change.
Is this specific to Azure?
The landing zone concept applies across Azure, AWS and Google Cloud, though the specific services and terminology differ. Design follows the equivalent framework for whichever platform you use.
How is the landing zone documented for our team?
Infrastructure-as-code templates, network diagrams and a governance document are delivered as part of the engagement, so the design is maintainable rather than dependent on institutional memory.
