Azure Resource Manager (ARM) is a service provided by Microsoft that helps manage resources in Azure. It provides a way to manage resources as a single unit, called a resource group, that can be deployed, updated, and deleted together. ARM allows you to define the infrastructure and application resources required for your application in a declarative JSON format called an ARM template, and then deploy and manage those resources using the Azure portal, PowerShell, or Azure CLI.
Some key benefits of using Azure Resource Manager to manage resources in Azure include:
Simplified deployment: ARM allows you to deploy and manage resources in a single step, instead of having to manage each resource individually.
Consistent management: ARM provides a consistent way to manage resources across Azure services, allowing you to manage resources consistently across different teams and projects.
Role-based access control: ARM provides role-based access control (RBAC), which allows you to grant granular permissions to users and groups based on their specific roles and responsibilities.
Tagging: ARM allows you to tag resources with metadata, such as cost center or environment, which can help with organizing and tracking resources.
Resource group lifecycle management: ARM allows you to manage the lifecycle of resource groups, including deploying and updating resources, and deleting resource groups when they are no longer needed.
Overall, Azure Resource Manager provides a powerful way to manage resources in Azure, by simplifying deployment, providing consistent management, enabling RBAC, tagging resources, and managing the lifecycle of resource groups. By using ARM, you can more easily manage your resources and applications in Azure, and help ensure that they are deployed and managed consistently across your organization.
