Each book explains ARM in context, with comparison tables and the common traps.

Terms in this definition

• Control plane

  Management layer used to create, configure and remove resources, as distinct from the data plane where they are used. Azure Resource Manager fills this role for Azure, and in AKS Azure operates the Kubernetes control plane on your behalf.

Related terms

• ARM template test toolkit

  Run via Test-AzTemplate, these PowerShell checks compare templates and parameter files against best practice for ARM. For Bicep, use the Bicep linter, since the toolkit can't check it.

• ASM

  Short for Azure Service Manager, the classic deployment model that came before Azure Resource Manager. New resources should not use it.

• Azure Deployment Environments

  Retiring on 22 February 2027 (Microsoft points people to Azure Verified Modules, Bicep or ARM deployments and Azure DevOps or GitHub workflows). Until then, it gives developers self-service app infrastructure built from curated IaC definitions kept in dev center catalogs, governed by platform engineers.

• azure/arm-deploy

  Action deploying Bicep or ARM templates to management groups, subscriptions or resource groups from GitHub.

• Bicep

  Domain-specific language for declaring Azure infrastructure as code, which is compiled into ARM templates.

• Checkov

  Open-source scanner for infrastructure-as-code that Microsoft Security DevOps runs; because it understands Terraform, ARM, Kubernetes manifests, CloudFormation, Helm charts and Dockerfiles, its format coverage exceeds Template Analyzer's.

• CloudAuditEvents

  Fed by Microsoft Defender for Cloud, this advanced hunting table captures control-plane activity in the cloud, for example Azure Resource Manager operations or Kubernetes audit records.

• copy (ARM template)

  Loop element in ARM templates for creating several resources, properties (for example storageProfile.dataDisks), variables or outputs, with a ceiling of 800 iterations.
