The critical resource organization design area establishes consistent patterns for organizing resources deployed to the cloud.
Design area review
Scope: Resource organization decisions are a foundation for all compliance-related design areas. The goal of resource organization planning is to establish consistent patterns for the following areas:
- Subscription design
- Management group design
The initial scope of this exercise assumes a subscription design that aligns with the Azure landing zone conceptual architecture. Workload- or application-level subscription and landing zone assignment supports separation of duties and subscription democratization requirements.
Out of scope: Alternative subscription design patterns are out of scope for this discussion. For alternative subscription design patterns, see Subscription design patterns.
The following assumptions are the basis for workload subscription design pattern guidance:
- Your enterprise is committed to long-term cloud operations.
- You need cloud management, security, and governance tooling to manage Azure, hybrid, or multicloud solutions.
- Management or platform deployments are in separate subscriptions and management groups from workload or application resources.
New cloud environment: To start your cloud journey with a small set of subscriptions, see Create your initial Azure subscriptions.
Existing cloud environment: Consider the following if you are interested in applying the principles from the resource organization design area to existing Azure environments:
- If your current environment does not use management groups, consider them. Management groups are key to managing policies, access, and compliance across subscriptions at scale. Management groups can help guide your implementation.
- If your current environment does use management groups, consider using the guidance in management groups when evaluating your implementation.
- If you have existing subscriptions in your current environment, consider using the guidance in subscriptions to see if you are using them effectively. Subscriptions act as policy and management boundaries and are scale units.
- If you have existing resources in your current environment, consider using the guidance in naming and tagging to influence your tagging strategy and your naming conventions going forward.
- Azure Policy is useful in establishing and enforcing consistency with regard to taxonomic tags.
Design area overview
Cloud adoption journeys have varying starting points and scale requirements. Some enterprises start with a few applications in the cloud and grow over time. Other enterprises must scale quickly to address business demands like a datacenter migration. In either scenario, resource organization planning should include environment growth to accommodate further applications and services.
A key consideration for resource organization design is to simplify management across the environment for increased workload numbers and scale. Azure landing zone design and implementation should consider foundational management group and subscription structure, to avoid creating scaling constraints later.
The resource organization design area explores techniques and technologies that help maintain good resource topologies in cloud environments. The following diagram shows the four scope levels for organizing Azure resources: management groups, subscriptions, resource groups, and resources.
