Deploy a Storage Account with ARM Templates

Azure Resource Manager (ARM) templates are a declarative Infrastructure as Code (IaC) solution for defining, deploying, and managing Azure resources using JSON. Rather than clicking through the Azure Portal, you describe the desired end state of your infrastructure in a template file, and Azure Resource Manager works out how to reach it. Templates are idempotent, so deploying the same file twice produces the same result, and they can be version-controlled, peer-reviewed, and promoted through environments like any other source code.

A template's power comes from its parameters, variables, and template functions. Parameters make a single template reusable across environments, variables keep repeated expressions in one place, and functions like concat() and uniqueString() generate deterministic values at deployment time, which matters for Azure services such as Storage that require globally unique names. Nested and dependent resources let a single template provision a parent resource and its children, so a Storage Account and its blob containers are created together as one coherent unit.

Objectives

By completing this Intermediate challenge, you will be able to:

• Author an ARM template with a valid schema, parameters, variables, resources, and outputs.
• Define parameters with explicit types and default values for reusable configuration.
• Generate globally unique resource names using the concat() and uniqueString() template functions.
• Provision an Azure Storage Account with a nested blob container resource.
• Deploy an ARM template to a resource group using the Azure CLI and verify the result.

Prerequisites

Before attempting this challenge, you should be comfortable with:

• ARM template structure (schema, contentVersion, parameters, variables, resources, outputs)
• Defining parameters with types and default values
• Using template functions like concat() and uniqueString()
• Deploying templates with Azure CLI
• Understanding nested and dependent resources
