description Complete list of Azure resources created by the landing zone

Resource Inventory

This is the complete inventory of every Azure resource created by the Startup Landing Zone deployment. Both the Bicep and Terraform implementations produce identical resources. Use this page as the single source of truth for what the landing zone deploys.

Naming convention prefix: {companyName}-{environment} (e.g., contoso-prod)

Resource Groups

Name Pattern Azure Resource Type Purpose Conditional
rg-{company}-{env}-monitoring Microsoft.Resources/resourceGroups Log Analytics workspace and monitoring resources Always created
rg-{company}-{env}-networking Microsoft.Resources/resourceGroups VNet, subnets, and NSGs Only when deployNetworking = true

Management Groups (Separate Deployment)

Management groups deploy at tenant scope and must be deployed separately before the main landing zone using CLI commands (see Quick Start Step 2 in the README). They are not created via the Portal or CI/CD workflows.

Name Pattern Azure Resource Type Purpose
mg-{company} Microsoft.Management/managementGroups Top-level management group for the landing zone

Hierarchy:

Tenant Root Group
└── mg-{company}  (display name: "{company} Landing Zone")
    ├── Production subscription
    └── Non-production subscription

Requires: Owner or Management Group Contributor on the Tenant Root Group.

Networking

Networking resources are created in rg-{company}-{env}-networking when deployNetworking = true.

Virtual Network

Property Prod Non-Prod
Name vnet-{company}-{env} vnet-{company}-{env}
Resource type Microsoft.Network/virtualNetworks —
Address space 10.0.0.0/16 10.1.0.0/16

Subnets

Subnet Name CIDR (Prod) CIDR (Non-Prod) Delegation Purpose
snet-aks 10.0.0.0/20 10.1.0.0/20 None AKS node pool
snet-app 10.0.16.0/22 10.1.16.0/22 Configurable (default: Microsoft.Web/serverFarms) App Service / Container Apps
snet-data 10.0.20.0/22 10.1.20.0/22 None Databases and data services
snet-shared 10.0.24.0/24 10.1.24.0/24 None Shared services (Key Vault, etc.)

Network Security Groups

Each subnet has a dedicated NSG. All NSGs include a DenyAllInbound catch-all rule at priority 4096.

NSG Name Azure Resource Type Associated Subnet
nsg-snet-aks Microsoft.Network/networkSecurityGroups snet-aks
nsg-snet-app Microsoft.Network/networkSecurityGroups snet-app
nsg-snet-data Microsoft.Network/networkSecurityGroups snet-data

Tags

Default tags applied to all resources and resource groups:

Tag Key Value Purpose
environment prod or nonprod Environment identification and cost tracking
managedBy bicep or terraform IaC tool used for deployment
project landing-zone Project identification
team platform Team ownership

Tag governance is enforced via policy:

  • environment and team tags are required on all resource groups (deny if missing).
  • environment and team tags are inherited from resource groups to child resources (auto-applied via Modify policy).

CI/CD Workflows

Workflow File Name Trigger Purpose
validate.yml Validate IaC PR and push to main on infra/** or examples/** Builds and lints all Bicep files; runs terraform fmt, TFLint, and terraform validate
deploy-bicep.yml Deploy Landing Zone (Bicep) Push to main on infra/bicep/**, PR, or manual dispatch Validates, runs What-If on PRs (posts result as PR comment), deploys nonprod and prod independently
deploy-terraform.yml Deploy Landing Zone (Terraform) Push to main on infra/terraform/**, PR, or manual dispatch Plans (posts result as PR comment), applies nonprod and prod independently (prod re-plans before apply)
integration-test.yml Integration Test Manual dispatch or weekly schedule (Monday 06:00 UTC) Runs Bicep What-If and Terraform Plan; optionally deploys, validates resources, and tears down
github-pages.yml Deploy to GitHub Pages Push to main or manual dispatch Builds Jekyll site and deploys to GitHub Pages
