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 like virtual machines, storage accounts, and networks in a reusable, version-controlled format. ARM Templates support idempotent deployments, ensuring consistent and repeatable infrastructure provisioning across environments.
Developers should learn ARM Templates when working with Azure to automate cloud resource management, enforce compliance, and streamline DevOps workflows. They are essential for scenarios like multi-environment deployments (e.g., dev, staging, production), disaster recovery setups, and managing complex Azure architectures with dependencies between resources. Using ARM Templates reduces manual errors and accelerates deployment cycles in CI/CD pipelines.
