Azure Resource Manager (ARM) is a management framework provided by Microsoft Azure that allows users to create, update, and delete resources in their cloud environment. It organizes resources into groups, making it easier to manage and deploy them collectively. This helps streamline operations and enhances resource organization. ARM uses a declarative template-based approach, enabling users to define the desired state of their infrastructure. This means you can specify what resources you need and how they should be configured, and ARM will handle the deployment. This simplifies the process of managing cloud resources and ensures consistency across deployments.
