The main benefit of using ARM templates is that they allow you to define the desired state of your Azure resources. This reduces the need for manual configurations and enables you to easily deploy and manage complex applications. ARM templates also support parameterization, which means you can use the same template to deploy different environments or configurations. Furthermore, they provide a way to handle dependencies between resources, ensuring that they are provisioned in the correct order.

ARM templates are a powerful tool for defining and provisioning Azure resources. They enable you to describe the infrastructure and configuration of your application in a declarative JSON format. With ARM templates, you can version control and automate the deployment of your resources, ensuring consistent and repeatable deployments. They can be used to create, update, or delete resources in Azure, making it easier to manage and scale your infrastructure.

ARM templates are an essential part of the Infrastructure as Code (IaC) approach. By treating infrastructure configurations as code, you can apply software development practices to your infrastructure, such as version control, code review, and continuous integration/continuous deployment (CI/CD). This helps improve collaboration, traceability, and reliability in your deployments. It also allows you to easily replicate your infrastructure across multiple environments, improving scalability and reducing the risk of configuration drift.
