Azure Landing Zones Part 1 - Building a Scalable and Secure Cloud Foundation

Welcome to the first chapter in our exciting journey through Azure Landing Zones! If you’ve ever felt overwhelmed by the complexities of setting up a scalable, secure, and well-governed cloud environment, you’ve come to the right place. This blog series is here to demystify Azure Landing Zones and give you the tools to succeed.

In this introductory post, we’ll break down what Azure Landing Zones are, why they’re essential, and how their components—including subscriptions—lay the groundwork for a powerful, scalable cloud environment. Plus, we’ll give you a sneak peek into the next post, where we’ll dive deep into configuring the Connectivity Subscription, the heart of your cloud’s network architecture.

Why Azure Landing Zones Matter

Azure Landing Zones are not just a tool—they’re a strategic blueprint for building cloud environments that are secure, scalable, and aligned with organizational governance requirements. Whether you’re setting up your first workload in Azure or scaling a multi-region enterprise, Landing Zones ensure you’re doing it right from day one.

What Makes Azure Landing Zones Essential?

  1. Scalability by Design: Expand your cloud footprint seamlessly as your needs grow.
  2. Centralized Governance: Apply consistent security, compliance, and operational policies across all resources.
  3. Optimized Costs: Track and allocate spending with pinpoint accuracy.
  4. Operational Excellence: Automate, monitor, and secure your environment with ease.

Landing Zones aren’t just for experts. They’re for anyone who wants to take control of their cloud environment and future-proof their Azure strategy.

The Foundation of Azure Landing Zones: Subscriptions

At the heart of every Azure Landing Zone is the subscription structure. Subscriptions are more than just containers for resources—they’re the backbone of resource organization, cost management, governance, and scalability. Get your subscriptions right, and you’ve already won half the battle!

Core Subscription Types in Azure Landing Zones

Here’s how Microsoft recommends structuring subscriptions in an Azure Landing Zone:

  1. Management Subscription:

    • Central hub for governance, operational tools, and shared platform services.
    • Includes tools like Azure Policy, Azure Monitor, and Defender for Cloud.

  2. Identity Subscription:

    • Manages secure access using Microsoft Entra ID (formerly Azure AD).
    • Includes hybrid identity tools, group management, and Key Vault for secrets.

  3. Connectivity Subscription:

    • Centralized networking hub for Virtual Networks (VNets), ExpressRoute, VPN Gateways, and Azure Firewall.
    • Acts as the backbone for communication between workloads and hybrid environments.
    • (This is the focus of our next post!)

  4. Landing Zone Subscriptions:

    • Host workloads, applications, and services.
    • Organized by workload type, team, or environment (e.g., Development, Testing, Production).

  5. Sandbox Subscription:

    • Isolated environment for experimentation, testing, and learning.

  6. Decommissioned Subscription:

    • Temporary storage for retired resources, ensuring compliance and orderly cleanup.

Organizing Subscriptions with Management Groups

To keep your subscriptions organized and governed, Microsoft recommends grouping them under Management Groups. Here’s a quick look at the ideal structure:

  1. Root Management Group:

    • Top-level container for all subscriptions.

  2. Platform Group:

    • Houses the Management, Identity, and Connectivity Subscriptions.
    • Provides governance and operational oversight for the entire Azure environment.

  3. Landing Zone Groups:

    • Groups subscriptions for workloads, business units, or applications (e.g., Landing Zone A1, A2).

  4. Sandbox Group:

    • Contains all Sandbox Subscriptions for innovation and testing.

  5. Decommissioned Group:

    • Manages subscriptions for retired resources awaiting deletion or compliance checks.

Why it this a Game-Changer

Think of subscriptions as your cloud’s organizational units. Each subscription serves a unique purpose, from centralizing management and security to isolating workloads and fostering innovation. By aligning with Azure Landing Zones’ subscription model, you’ll:

  • Simplify Resource Management: Easily track resources by subscription.
  • Enhance Governance: Apply consistent policies and access controls.
  • Optimize Costs: Allocate spending accurately to business units or workloads.
  • Boost Security: Isolate environments to reduce risk.
