Azure Resource Manager Templates
Azure Resource Manager (ARM) Templates are JSON-based declarative configuration files used to define and deploy infrastructure and applications on Microsoft Azure. They enable infrastructure as code (IaC) by specifying resources, dependencies, and configurations in a reusable, version-controlled format. ARM Templates are processed by the Azure Resource Manager service to provision and manage Azure resources consistently and predictably.
Developers should learn ARM Templates for automating and standardizing Azure deployments, especially in DevOps, cloud migration, and multi-environment scenarios. They are essential for implementing infrastructure as code practices, enabling repeatable deployments, reducing manual errors, and facilitating collaboration through version control. Use cases include deploying complex multi-tier applications, managing resource lifecycles, and ensuring compliance with organizational policies.
