Azure Landing Zone: Building a Secure Foundation for Cloud Migration Success

Azure

Moving to the cloud isn't just about lifting and shifting workloads—it's about creating a robust foundation that enables your organization to scale securely and efficiently. For businesses looking to migrate to Microsoft Azure, implementing a proper Landing Zone is the critical first step that many organizations unfortunately overlook.

In today's rapidly digitizing world, moving to the cloud is a strategic imperative for many businesses. Efficient and structured cloud migration is the key to maximizing benefits like flexibility, scalability, and cost efficiency. Azure Landing Zone provides that structured approach, ensuring your cloud environment is built on solid architectural principles from day one.

What Exactly Is an Azure Landing Zone?

An Azure Landing Zone is essentially an empty Azure subscription that you can populate with the workloads and applications (pre-provisioned through code) you wish to deploy on Azure. But it's much more than just a blank canvas—it's a carefully architected environment designed according to Microsoft's Cloud Adoption Framework that sets your organization up for long-term cloud success.

Azure Landing Zone is an environment that follows key design principles across eight design areas. These design principles accommodate all application portfolios and enable application migration, modernization, and innovation at scale. It serves as the blueprint for how your organization will structure, secure, govern, and manage your cloud resources.

The Architectural Framework of Azure Landing Zones

At its core, an Azure Landing Zone consists of two main subscription types:

  1. Platform Landing Zones: A platform landing zone is a subscription that provides shared services (identity, connectivity, management) to applications in application landing zones. Consolidating these shared services often improves operational efficiency. These are managed by central IT teams.
  2. Application Landing Zones: An application landing zone is a subscription for hosting an application. These provide the environment where workload teams deploy and manage their applications.

This separation creates a clear boundary between shared infrastructure services and application-specific resources, improving security, governance, and operational efficiency.

Eight Critical Design Areas of Azure Landing Zones

Each Azure landing zone implementation option provides a deployment approach and defined design principles. Learn about these design areas before choosing an implementation option. The eight foundational design areas include:

1. Azure Billing and Microsoft Entra Tenant

This area focuses on how your organization structures its billing relationship with Microsoft and establishes the core identity services through Microsoft Entra ID (formerly Azure AD). Proper planning here ensures your subscription model aligns with your organizational structure and business needs.

2. Identity and Access Management

Access control underpins security and compliance in any cloud infrastructure. IAM erects a security boundary that allows only permitted users, apps, and services to access protected corporate resources hosted on the cloud. A robust identity strategy is the cornerstone of Zero Trust security implementation.

3. Management Group and Subscription Organization

Resource organization focuses on how subscriptions, resources, and solutions are set up in order to align with specific goals. This means finding the most efficient resource combination for cloud migration. This hierarchical structure creates the governance backbone for your entire Azure environment.

4. Network Topology and Connectivity

The networking aspect looks at how various resources and tools communicate with each other, within and outside the cloud environment. Proper network design ensures secure communication pathways between on-premises systems, the internet, and various Azure services.

5. Security

While organizations can never have perfect security, there's still the pragmatic approach of Business resilience in investing the full lifecycle of a security risk before, during, and after an incident. Microsoft Your Azure Landing Zone should incorporate security controls, monitoring, and compliance requirements from the start.

6. Management

When you've achieved the Ready state and implemented Azure landing zones, you still have an ongoing responsibility to manage your cloud environment in the most efficient way possible. Microsoft This area establishes how you'll monitor, update, and maintain your Azure environment over time.

7. Governance

A good cloud governance model gives you visibility and control over your cloud investments, usage, and security. This includes implementing Azure Policy, cost management, and compliance controls that align with your organizational requirements.

8. Platform Automation and DevOps

Implementing Infrastructure-as-Code (IaC) practices allows for consistent, repeatable deployments and enables your organization to adopt modern DevOps practices for managing both infrastructure and applications.

Implementation Approaches: Choose Your Path

There are two primary approaches. The choice will depend on how fast your teams can develop the required skills.

Start Small and Expand

This path provides a flexible cloud deployment approach with minimal controls. It's ideal for organizations looking to migrate to the cloud at a low-risk pace. You can begin with a simpler implementation and add complexity as your cloud maturity grows.

Enterprise-Scale

An enterprise-scale Landing Zone architecture has a modular design and puts governance, security, and regulatory compliance controls at the very start. This is for those wanting to deploy company-wide workloads onto the cloud in one go instead of taking an incremental migration approach.

Why Azure Landing Zone Is Essential for Cloud Success

Implementing an Azure Landing Zone before migration provides numerous benefits:

1. Standardized, Repeatable Architecture

The repeatable infrastructure allows you to apply configurations and controls to every subscription consistently. This standardization reduces the risk of configuration drift and security vulnerabilities.

2. Enhanced Security Posture

If your organization adheres to the Zero Trust strategy, you should incorporate Zero Trust-specific deployment objectives into your landing zone design areas. Your landing zone is the foundation of your workloads in Azure, so it's important to prepare your landing zone for Zero Trust adoption.

3. Governance and Compliance by Design

It's important to ensure that your deployed landing zone environment is up to date so that you can maintain improved security, avoid platform configuration drift, and stay optimized for new feature releases. A well-designed landing zone makes ongoing compliance management significantly easier.

4. Operational Efficiency

A management baseline establishes the foundation for operations management. It represents the minimum set of tools and processes that should be applied to every asset in a cloud environment. This baseline drives consistency and efficiency.

5. Future-Proof Scalability

Use application landing zones for centrally managed applications, decentralized workloads that application teams own, and centrally managed hosting platforms such as Azure Kubernetes Service (AKS) that could host applications for multiple business units. This architecture supports long-term scalability.

Best Practices for Azure Landing Zone Success

To maximize the value of your Azure Landing Zone implementation:

Conduct a Thorough Assessment

If you are planning to build an Azure Landing Zone, it is important to consider the specific requirements of your organization. Start with a comprehensive assessment of your current environment, workloads, and business requirements.

Leverage Infrastructure as Code (IaC)

Maintain your ALZ environment with IaC to consistently stay updated with ALZ. Using tools like Azure Resource Manager templates, Terraform, or Bicep provides consistency and enables version control of your infrastructure.

Implement Network Segmentation

Delegate subnet creation to the landing zone owner. This will enable them to define how to segment workloads across subnets (for example, a single large subnet, multitier application, or network-injected application). Proper segmentation enhances security and operational control.

Align with Azure's Design Principles

The Azure landing zone conceptual architecture universally applies to any Azure landing zone process or implementation. At the foundation of the architecture, a set of core design principles serve as a compass for subsequent design decisions across critical technical domains.

Plan for Continuous Improvement

Keeping your landing zone up to date helps you mitigate the risk of a security breach and helps you keep your data properly secured. Regularly review and update your landing zone design and implementation as Azure evolves and your organization's needs change.
