Definition
Azure Resource Manager (ARM) templates are JSON files that define the infrastructure and configuration for your cloud solutions. They allow you to declaratively describe the resources you want to deploy, such as virtual machines, storage accounts, and virtual networks, along with their dependencies and settings. By using ARM templates, you can automate the deployment and management of your cloud environment, ensuring consistency and repeatability across different stages of development and operations. For instance, you can use an ARM template to spin up a complete web application environment with databases and load balancers in minutes. Unlike imperative scripting where you specify commands to execute, ARM templates focus on the desired end state of your resources. Understanding ARM templates is crucial for cloud engineers and architects and is frequently tested on AWS certification exams like the AWS Certified Solutions Architect Associate.
