Our team structures Azure subscriptions and resource groups to ensure clear governance and effective cost control. We typically create separate subscriptions for different environments—such as development, testing, and production—so that each environment’s resources are isolated for easier management of access, billing, and compliance. This separation allows us to apply different policies, monitor costs, and track usage independently per subscription. Within each subscription, we organize resources into multiple resource groups based on application or service, which makes resource management more intuitive. Each resource group contains related resources like virtual machines, networks, and databases, making it easier to apply access controls and enforce governance policies using role-based access control (RBAC) and Azure Policy. We also use tags to track resource usage and associate costs with specific departments or projects. This structure enables us to maintain tight control over costs, optimize resource allocation, and ensure compliance across different environments.
