Azure Platform Foundation

This documentation series describes how I approach the foundation of an Azure platform before production workloads are deployed.

The goal is not to create a perfect enterprise template. The goal is to document the core decisions that make an Azure environment secure, understandable, repeatable, and maintainable.

What this series covers

An Azure platform foundation usually includes:

• Management group and subscription structure
• Identity and access control
• Networking, routing, DNS, and private connectivity
• Governance with Azure Policy
• Monitoring, logging, and security visibility
• Infrastructure as Code and deployment workflows
• Operational standards for long-term maintainability

Design goals

The platform should make the secure path the easy path.

That means:

• Access is assigned intentionally.
• Network paths are understandable.
• Public exposure is avoided unless required.
• Policies enforce baseline rules.
• Logs and alerts are available from the beginning.
• Changes are versioned and repeatable.
• Documentation explains why decisions were made.

Suggested reading order

1. Platform principles
2. Management group structure
3. Identity and RBAC
4. Network foundation
5. Governance baseline
6. Monitoring and operations
7. Infrastructure as Code

Scope

This series focuses on the Azure platform foundation, not individual application workloads.

Workloads such as App Service, AKS, virtual machines, databases, and private endpoints will be covered later as separate workload guides.
