Explanation of Azure Resource Manager (ARM) and Classic Deployment Model in Azure

One frequently asked question in Azure interviews is about the difference between Azure Resource Manager (ARM) and the classic deployment model in Azure.

Azure Resource Manager (ARM)

Azure Resource Manager (ARM) is the modern management framework that allows you to deploy, manage, and organize Azure resources efficiently. It provides a way to create and manage resources within a subscription. With ARM, you can deploy related resources as a group and manage them collectively.

Classic Deployment Model

The classic deployment model, also known as the Azure Service Management (ASM) model, is the traditional way of deploying and managing resources in Azure. In this model, resources are managed individually, making it harder to group related resources together. It has limited capabilities compared to ARM.

Overall, ARM offers improved resource management, easier deployment, and better organization of resources compared to the classic deployment model.

Understanding the differences between ARM and the classic deployment model is essential for successfully working with Azure resources and deployments.
