Learn AZURE-ARM with Real Code Examples
Updated Nov 27, 2025
Architecture
ARM templates define resources, parameters, variables, and outputs
Resources deployed within resource groups
Azure Resource Manager orchestrates deployment and tracks state
Supports linked or nested templates for modularity
Integrates with Azure Policy and RBAC for governance
Rendering Model
Template defines desired state of resources
ARM orchestrates deployment to Azure services
Resource dependencies resolved automatically
Deployment validated before execution
State tracked by Azure Resource Manager
