This blog compares the AzureRM and AzAPI Terraform providers for optimal Azure infrastructure management. AzureRM provides a stable, well-tested layer on top of Azure APIs, while AzAPI is a lightweight wrapper around Azure APIs, enabling direct access to the latest features. AzureRM is ideal for users looking for stability and simplified configuration management, whereas AzAPI is recommended for scenarios where early access to new Azure features is crucial or when granular control over resource versions is needed. Both providers are backed by Microsoft and HashiCorp and can be adapted based on user needs.
