Cloud Architecture & Landing Zones

Establish secure, well-architected Azure foundations aligned to Microsoft Cloud Adoption Framework. Landing zones that scale, govern, and protect from day one.

Why Architecture Matters

Most cloud failures result from architectural decisions rather than technology. When foundational design is overlooked or undervalued, organisations face increased security risk, escalating costs, and cloud platforms that fail to support sustainable growth.

No Clear Foundation

Resources are fragmented across subscriptions with inconsistent standards, reducing visibility and obscuring critial dependencies.

Security as an Afterthought

Retrofitted controls and policies increase compliance costs and materially elevate security, regulatory and reputational risk.

Cost Surprises

Azure spend continues to rise without clear visibility into cost drivers or accountability for consumption.

Can't Scale Safely

New workloads require manual rework, increasing delivery risk and preventing consistent, controlled growth.

Governance Gaps

Policies exist without effective enforcement, allowing unmanaged Azure uage to increase risk, cost, and compliance exposure.

The Cost of Getting It Wrong

  • Elevated security risk from misconfiguration
  • Elevated costs from weak foundations
  • Audit failures and adverse compliance findings
  • Costly remediation to fix weak cloud foundation
  • Slower, riskier adoption of new cloud services

How We Build Azure Foundations

We design Azure landing zones that embed security and governance by default, enabling scalable growth while maintaining clear control and accountability.

1

Assess & Align

Assess the current Azure environment, regulatory obligations, and strategic alignment with the Microsoft Cloud Adoption Framework

2

Design Architecture

Define the target Azure architecture and governance model to ensure security, scalability, and operational control.

3

Build Foundation

Establish a secure, production ready Azure landing zone with core networking, policy, and security controls.

4

Enable & Handover

Validate the platform with live workloads and transition ownership with clear accountability, documentation, and operating models.

Deliverables & Outcomes

A fully governed Azure foundation with clear documentation and operational rediness from day one.

Management Group Hierarchy

Structured management group model that clearly separates production, non-production, sandboxes, and platform services to enforce governance and accountability.

Subscription Design

Right-sized Azure subscriptions with clear ownership, defined purpose, and enforced financial boundaries.

Network Architecture

Standardised hub-and-spoke or Virtual WAN topology that centralises connectivity and enforces consistent network security.

Identity Foundation

Standardised identity model with Entra ID integration, role base access control (RBAC), and governed privileged access aligned to Zero Trust principles.

Policy & Governance

Azure Policy that enforces security baselines, approved regions, mandatory tagging, and permitted resource types to ensure consistent governance and compliance.

Cost Management

Budgets, automated cost controls, and a standardised tagging and allocation model delivering immediate and ongoing financial visibility.

Security Baseline

Defender for Cloud, comprehensive diagnostic logging, and industry aligned security benchmarks implemented to deliver a consistent and auditable security posture.

Operations Baseline

Azure Monitor, centralised Log Analytics, and proative alerting implemented to provide continuous health and operational visibility.

Typical Outcomes

  • 30-50% cost reduction through right-sizing
  • Deployment cycles reduced from weeks to days
  • Audit ready Azure aligned to Essential Eight and ISM
  • Consistent, enforceable security across the platform
  • Clear accountability via structured RBAC
  • Scalable foundation enabling growth without added risk
