Azure Resource Manager
Azure Resource Manager (ARM) is the deployment and management service for Azure resources. It provides a consistent management layer that enables users to create, update, and delete resources in their Azure subscription through templates, scripts, or the Azure portal. ARM organizes resources into resource groups for easier management, billing, and access control.
Developers should learn ARM when working with Azure to automate infrastructure deployment and management, ensuring consistency and repeatability across environments. It is essential for implementing Infrastructure as Code (IaC) practices in Azure, enabling version control, testing, and collaboration on cloud resource configurations. Use cases include deploying complex multi-tier applications, managing environments (dev/test/prod), and enforcing governance policies through templates.
