Diving into Azure Bicep

Now that we’ve familiar with Azure Bicep and the simplicity it brings to infrastructure management, let’s dive deeper into its capabilities. Azure Bicep represents Microsoft’s latest attempt to simplify the IaC authoring experience. It emerges as a domain-specific language (DSL) crafted to articulate cloud resources with ease and precision. Unlike its predecessor, the JSON-centric ARM templates, Bicep unveils a clean, readable syntax that eases the translation of infrastructure blueprints into code.

Take a peek at this playful ‘Hello World!’ snippet showcasing Bicep’s syntax:

param message string
var hello = 'Hello World!'
output hello_World string = '${hello} ${message}'

Upon compilation, this snippet morphs into an ARM template:

{
  "$schema": "https://schema.management.azure.com/schemas/2019-04-01/deploymentTemplate.json#",
  "contentVersion": "1.0.0.0",
  "parameters": {
    "message": {
      "type": "string"
    }
  },
  "functions": [],
  "variables": {
    "hello": "Hello World!"
  },
  "resources": [],
  "outputs": {
    "hello_World": {
      "type": "string",
      "value": "[concat(variables('hello'), parameters('message'))]"
    }
  }
}

The contrast in verbosity between Bicep and JSON highlights the simplicity Bicep aspires to achieve. Here’s the real JSON export of the ‘Hello World!’ Bicep snippet to illustrate the transformation.
