Security is a top concern when migrating applications to the cloud. Azure Landing Zones help address these concerns by providing a solid foundation for security and compliance best practices. With predefined security policies and controls, organizations can ensure consistent security configurations across their cloud environment. This includes identity and access management, network security, data protection, and compliance with industry regulations.

Standardized Governance

Maintaining governance and control in a cloud environment can be complex, especially as the infrastructure scales. Azure Landing Zones establish standardized governance models, enabling a centralized approach to managing resources, access permissions, and cost controls. By adopting these predefined governance policies, companies can avoid shadow IT and maintain full visibility and control over their cloud assets.

Improved Cost Management

Proper implementation of Azure Landing Zones allows organizations to optimize cloud costs effectively. By following best practices for resource organization and using Azure’s cost management tools, businesses can track their cloud spending, identify cost-saving opportunities, and avoid unexpected expenses.

Increased Scalability and Flexibility

Azure Landing Zones are designed to accommodate future growth and changing business requirements seamlessly. By setting up a scalable and flexible foundation, companies can expand their cloud infrastructure to meet the evolving needs of their applications without encountering bottlenecks or architectural constraints.

Streamlined Collaboration

For companies with multiple teams or departments involved in the migration process, Azure Landing Zones provide a standardized framework that fosters collaboration and communication. This shared approach ensures that everyone follows the same guidelines, leading to consistent results and a smoother migration experience.

Azure Landing Zone Architecture

The architecture of an Azure landing zone is designed to be flexible and adaptable, catering to various deployment requirements. Its modular and scalable nature enables consistent application of configurations and controls across all subscriptions. By utilizing modules, specific components of the Azure landing zone can be easily deployed and adjusted as your needs evolve over time.
 
The conceptual architecture of the Azure landing zone, depicted below, serves as a recommended blueprint, providing an opinionated and target design for your cloud environment. However, it should be viewed as a starting point rather than a rigid framework. It is essential to tailor the architecture to align with your organization’s unique needs, ensuring that the Azure landing zone perfectly fits your requirements.

Landing Zone Types

An Azure Landing Zone can be either a Platform Landing Zone or an Application Landing Zone. A more detailed explanation of their respective functions is valuable to gain a comprehensive understanding of their roles in cloud architecture.

Platform Landing Zones

Platform Landing Zones, also known as Foundational Landing Zones, provide the core infrastructure and services required for hosting applications in Azure. They are the initial building blocks that establish a well-structured and governed foundation for the entire cloud environment.
 
The primary focus of Platform Landing Zones is on creating a robust and scalable infrastructure to host applications. They address common requirements, such as identity and access management, networking, security, monitoring, and compliance. These landing zones provide shared services that are consumed by multiple application workloads.
 

Key Features of Platform Landing Zones

Below are some key features of Platform Landing Zones:

  • Identity and Access Management: Platform Landing Zones set up centralized identity and access control mechanisms using Microsoft Entra ID (formerly known as Azure Active Directory or AAD), to manage user identities and permissions effectively.
  • Networking: They establish virtual networks, subnets, and network security groups to ensure secure communication and connectivity between various resources.
  • Security and Compliance: Platform Landing Zones implement security best practices and policies to protect the cloud environment and ensure compliance with industry standards and regulations.
  • Governance and Cost Management: Platform Landing Zones include resource organization, tagging, and governance mechanisms to facilitate cost allocation, tracking, and optimization.
  • Shared Services: Platform Landing Zones may include shared services like Azure Policy, Azure Monitor, and Azure Log Analytics to ensure consistent management and monitoring.

Application Landing Zones

Application Landing Zones focus on the specific requirements of individual applications or application types. They are designed to host and optimize the deployment of a particular application workload in Azure.
 
The primary focus of Application Landing Zones is on the unique needs of applications. They address factors such as application architecture, performance, scalability, and availability. Each Application Landing Zone is tailored to meet the demands of a specific application or application family.
 

Key Features of Application Landing Zones

Below are some key features of Application Landing Zones:

  • Application Architecture: Application Landing Zones include resources and configurations specific to the application’s architecture, such as virtual machines, containers, or serverless functions.
  • Performance Optimization: Application Landing Zones may implement caching mechanisms, content delivery networks (CDNs), or other optimizations to enhance application performance.
  • Scalability and Availability: They leverage Azure’s auto-scaling capabilities, load balancers, and availability sets or zones to ensure the application can handle varying workloads and maintain high availability.
  • Data Storage and Management: Application Landing Zones include configurations for databases and data storage solutions, such as Azure SQL Database, Azure Cosmos DB, or Azure Blob Storage, depending on the application’s data requirements.
  • Application-Specific Security: Application Landing Zones may have customized security settings and access controls based on the application’s sensitivity and compliance requirements.

Platform vs. Application Landing Zones Summary

In summary, Platform Landing Zones focus on providing a standardized and governed foundation for the entire cloud environment, addressing infrastructure and shared services needs. They set the stage for consistent management, security, and cost optimization across the organization’s Azure resources. On the other hand, Application Landing Zones concentrate on tailoring the cloud environment to suit the specific requirements of individual applications, optimizing performance, scalability, and data management for each workload.
 

Both Platform Landing Zones and Application Landing Zones play crucial roles in a successful Azure cloud adoption strategy. Platform Landing Zones ensure the overall health and governance of the cloud environment, while Application Landing Zones cater to the unique needs of diverse application workloads, enabling efficient and optimized hosting of applications in Azure.
