Azure landing zones Terraform module

Detailed information about how to use, configure and extend this module can be found on our Wiki:

‼ Notice of upcoming breaking changes

We are planning to make some breaking changes to the module in the next release (Q4 2024).

Module defaults will updated to deploy zone redundant SKUs by default - this applies to:
- Firewall
- Public IP
- Virtual Network Gateway

We will publish guidance on how to avoid re-deployment of existing resources nearer the time.

Overview

The Azure landing zones Terraform module is designed to accelerate deployment of platform resources based on the Azure landing zones conceptual architecture using Terraform.

This is currently split logically into the following capabilities within the module (links to further guidance on the Wiki):

Module capability	Scope	Design area
Core Resources	Management group and subscription organization	Resource organization
Management Resources	Management subscription	Management
Connectivity Resources	Connectivity subscription	Network topology and connectivity
Identity Resources	Identity subscription	Identity and access management

Using a very simple initial configuration, the module will deploy a management group hierarchy based on the above diagram. This includes the recommended governance baseline, applied using Azure Policy and Access control (IAM) resources deployed at the management group scope. The default configuration can be easily extended to meet differing requirements, and includes the ability to deploy platform resources in the management and connectivity subscriptions.

NOTE: In addition to setting input variables to control which resources are deployed, the module requires setting a Provider Configuration block to enable deployment across multiple subscriptions.

Although resources are logically grouped to simplify operations, the modular design of the module also allows resources to be deployed using different Terraform workspaces. This allows customers to address concerns around managing large state files, or assigning granular permissions to pipelines based on the principle of least privilege. (more information coming soon in the Wiki)

Terraform versions

This module has been tested using Terraform 1.7.0 and AzureRM Provider 3.108.0 as a baseline, and various versions to up the latest at time of release. In some cases, individual versions of the AzureRM provider may cause errors. If this happens, we advise upgrading to the latest version and checking our troubleshooting guide before raising an issue.

Usage

We recommend starting with the following configuration in your root module to learn what resources are created by the module and how it works.

This will deploy the core components only.

NOTE: For production use we highly recommend using the Terraform Registry and pinning to the latest stable version, as per the example below. Pinning to the main branch in GitHub will give you the latest updates quicker, but increases the likelihood of unplanned changes to your environment and unforeseen issues.

`main.tf`

# Configure Terraform to set the required AzureRM provider
# version and features{} block.

terraform {
  required_providers {
    azurerm = {
      source  = "hashicorp/azurerm"
      version = "~> 3.107"
    }
  }
}

provider "azurerm" {
  features {}
}

# Get the current client configuration from the AzureRM provider.
# This is used to populate the root_parent_id variable with the
# current Tenant ID used as the ID for the "Tenant Root Group"
# management group.

data "azurerm_client_config" "core" {}

# Use variables to customize the deployment

variable "root_id" {
  type    = string
  default = "es"
}

variable "root_name" {
  type    = string
  default = "Enterprise-Scale"
}

variable "default_location" {
  type    = string
}

# Declare the Azure landing zones Terraform module
# and provide a base configuration.

module "enterprise_scale" {
  source  = "Azure/caf-enterprise-scale/azurerm"
  version = "<version>" # change this to your desired version, https://www.terraform.io/language/expressions/version-constraints

  default_location = var.default_location

  providers = {
    azurerm              = azurerm
    azurerm.connectivity = azurerm
    azurerm.management   = azurerm
  }

  root_parent_id = data.azurerm_client_config.core.tenant_id
  root_id        = var.root_id
  root_name      = var.root_name

}

Required Inputs

The following input variables are required:

default_location

Description: Must be specified, e.g eastus. Will set the Azure region in which region bound resources will be deployed. Please see: https://azure.microsoft.com/en-gb/global-infrastructure/geographies/

Type: string

root_parent_id

Description: The root_parent_id is used to specify where to set the root for all Landing Zone deployments. Usually the Tenant ID when deploying the core Enterprise-scale Landing Zones.

Type: string

Optional Inputs

The following input variables are optional (have default values):

archetype_config_overrides

Description: If specified, will set custom Archetype configurations for the core ALZ Management Groups.
Does not work for management groups specified by the 'custom_landing_zones' input variable.
To override the default configuration settings for any of the core Management Groups, add an entry to the archetype_config_overrides variable for each Management Group you want to customize.
To create a valid archetype_config_overrides entry, you must provide the required values in the archetype_config_overrides object for the Management Group you wish to re-configure.
To do this, simply create an entry similar to the root example below for one or more of the supported core Management Group IDs:

root
decommissioned
sandboxes
landing-zones
platform
connectivity
management
identity
corp
online
sap

map(
  object({
    archetype_id     = string
    enforcement_mode = map(bool)
    parameters       = map(any)
    access_control   = map(list(string))
  })
)

e.g.

  archetype_config_overrides = {
    root = {
      archetype_id = "root"
      enforcement_mode = {
        "Example-Policy-Assignment" = true,
      }
      parameters = {
        Example-Policy-Assignment = {
          parameterStringExample = "value1",
          parameterBoolExample   = true,
          parameterNumberExample = 10,
          parameterListExample = [
            "listItem1",
            "listItem2",
          ]
          parameterObjectExample = {
            key1 = "value1",
            key2 = "value2",
          }
        }
      }
      access_control = {
        Example-Role-Definition = [
          "00000000-0000-0000-0000-000000000000", # Object ID of user/group/spn/mi from Microsoft Entra ID
          "11111111-1111-1111-1111-111111111111", # Object ID of user/group/spn/mi from Microsoft Entra ID
        ]
      }
    }
  }

    azurerm_role_definition       = optional(string, "60s")
  })

Default: {}

custom_landing_zones

Description: If specified, will deploy additional Management Groups alongside Enterprise-scale core Management Groups.
Although the object type for this input variable is set to any, the expected object is based on the following structure:

variable "custom_landing_zones" {
  type = map(
    object({
      display_name               = string
      parent_management_group_id = string
      subscription_ids           = list(string)
      archetype_config = object({
        archetype_id   = string
        parameters     = map(any)
        access_control = map(list(string))
      })
    })
  )

The decision not to hard code the structure in the input variable type is by design, as it allows Terraform to handle the input as a dynamic object type.
This was necessary to allow the parameters value to be correctly interpreted.
Without this, Terraform would throw an error if each parameter value wasn't a consistent type, as it would incorrectly identify the input as a tuple which must contain consistent type structure across all entries.

Note the id of the custom landing zone will be appended to var.root_id. The maximum length of the resulting name must be less than 90 characters.

The custom_landing_zones object is used to deploy additional Management Groups within the core Management Group hierarchy.
The main object parameters are display_name, parent_management_group_id, subscription_idsand archetype_config.

display_name is the name assigned to the Management Group.
parent_management_group_id is the name of the parent Management Group and must be a valid Management Group ID.
subscription_ids is an object containing a list of Subscription IDs to assign to the current Management Group.
archetype_config is used to configure the configuration applied to each Management Group. This object must contain valid entries for the archetype_id parameters, and access_control attributes.

The following example shows how you would add a simple Management Group under the myorg-landing-zones Management Group, where root_id = "myorg" and using the default_empty archetype definition.

  custom_landing_zones = {
    myorg-customer-corp = {
      display_name               = "MyOrg Customer Corp"
      parent_management_group_id = "myorg-landing-zones"
      subscription_ids           = [
        "00000000-0000-0000-0000-000000000000",
        "11111111-1111-1111-1111-111111111111",
      ]
      archetype_config = {
        archetype_id   = "default_empty"
