Introduction to Azure Resource Manager (ARM) Templates

Azure Resource Manager (ARM) templates provide a powerful, declarative approach to automate the deployment and management of resources in Microsoft Azure. ARM templates allow users to define resources, configurations, and dependencies in JSON format. With ARM templates, you can achieve infrastructure-as-code (IaC) by ensuring consistent deployments while tracking changes and automating infrastructure provisioning.

ARM templates streamline the deployment process by letting users declare what resources they want, and Azure takes care of creating them in the correct order, handling dependencies, and managing resource lifecycles.

Key Features of ARM Templates:

• Declarative syntax: You declare your resources without needing to worry about the specific commands required to create them.
• Idempotent: The same template can be used multiple times for deployments, and Azure will ensure the desired state without duplicating resources.
• Composability: ARM templates allow you to modularize complex infrastructure into smaller reusable pieces.
• Extensibility: You can define parameters, variables, outputs…
