Azure Resource Manager

Azure Resource Manager (ARM) is Azure's deployment and management service, providing a layer to create, update, and delete resources within your Azure account. It offers management features like access control, locks, and tags for securing and organizing resources post-deployment.

ARM acts as an intermediary for requests sent through Azure APIs, tools, or SDKs, ensuring authentication, authorization, and consistent results across different tools. All capabilities available in the Azure portal are also accessible through PowerShell, Azure CLI, REST APIs, and client SDKs.
