From the author

Architect and provision enterprise Azure infrastructure from workload descriptions. For cloud architects and platform engineers planning networking, identity, security, compliance, and multi-resource topologies with WAF alignment. Generates Bicep or Terraform directly (no azd). WHEN: 'plan Azure infrastructure', 'architect Azure landing zone', 'design hub-spoke network', 'plan multi-region DR topology', 'set up VNets firewalls and private endpoints', 'subscription-scope Bicep deployment', 'Azure Backup for VM workloads'. PREFER azure-prepare FOR app-centric workflows.

AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

This skill guides users through a 7-phase pipeline to design and deploy Azure infrastructure. It processes workload descriptions to generate Bicep or Terraform code, supporting both greenfield deployments and additive updates to existing environments. The process includes research, planning, user approval, and automated validation using security and syntax checks before deployment.

What it does

  • Extracts insights from workload descriptions to inform infrastructure planning.
  • Researches Azure best practices and service-specific documentation.
  • Generates infrastructure plans and corresponding Bicep or Terraform code.
  • Validates generated IaC using syntax checks and security scanning tools.
  • Supports additive deployments for existing environments without modifying referenced resources.
  • Manages multi-resource topologies including networking, identity, and compliance configurations.

When to use it

  • When planning Azure infrastructure from a workload or architecture description.
  • When designing hub-spoke networks, landing zones, or multi-region topologies.
  • When setting up networking components like VNets, firewalls, and private endpoints.
  • When generating subscription-scope or multi-resource-group infrastructure code.

Advantages

  • Follows a structured, gated pipeline to ensure plan approval and code validation.
  • Integrates security scanning and syntax validation into the generation workflow.
  • Provides support for referencing existing resources to avoid accidental recreation.
  • Utilizes specific Azure schema data to ensure accurate resource definitions.

Usage examples

“Plan Azure infrastructure for a hub-spoke network with firewalls.”
The agent initiates the 7-phase pipeline, researching networking best practices and generating the corresponding IaC for the requested topology.
“Architect an Azure landing zone.”
The agent guides the user through requirements extraction and resource planning, resulting in a structured infrastructure plan and Bicep or Terraform files.

Workflow (Start Here)

Follow the step-by-step instructions in workflow.md to execute the 7 phases of infrastructure planning and provisioning.

Architecture

The skill runs a 7-phase, gated pipeline. Input is triaged into one of two flows:

  • Greenfield — only new requirements; run the phases straight through.

  • Referenced (brownfield) — the user supplies something that already exists (a live resource / resource group / subscription, IaC or an infra plan, or a requirements doc). The same phases run, plus referenced-workload.md: existing resources are inventoried and referenced (never recreated), the new workload is wired into them, and Phase 7 deploys additively (incremental only — never modifying or destroying the referenced resources).

Every phase advances only after its gate passes. Phase 5 requires explicit user approval; Phase 6 is a hardened, self-verifying gate — the generated IaC must be secure-by-default, pass local validation (az bicep build / terraform validate) with zero errors, pass a checkov security scan with no unresolved high/critical findings, and the skill must show the command output and emit a completion self-check before advancing; Phase 7 requires an explicit, risk-acknowledged deploy confirmation.

Compute (IaaS) Pairing Constraints

AKS Cluster
Paired WithConstraint
VNet / SubnetWith Azure CNI, subnet must have enough IPs for nodes + pods (30 pods/node default × node count). Subnet cannot have other delegations. Reserved CIDR ranges cannot be used: 169.254.0.0/16, 172.30.0.0/16, 172.31.0.0/16, 192.0.2.0/24.
Pod CIDRPod CIDR must not overlap with cluster subnet, peered VNets, ExpressRoute, or VPN address spaces. Overlapping causes SNAT/routing issues.
kubenetKubenet uses NAT — subnet only needs IPs for nodes. Less IP pressure but no direct pod-to-VNet connectivity. Kubenet is retiring March 2028 — migrate to CNI Overlay. Not supported by Application Gateway for Containers.
CNI OverlayCNI Overlay does not support VM availability sets (must use VMSS-based node pools), virtual nodes, or DCsv2-series VMs (use DCasv5/DCadsv5 instead).
Dual-stack CNI OverlayIPv4+IPv6 dual-stack disables Azure/Calico network policies, NAT gateway, and virtual nodes.
Key VaultEnable azureKeyvaultSecretsProvider addon. Use enableRbacAuthorization: true on Key Vault with managed identity.
Container RegistryAttach ACR via acrPull role assignment on cluster identity, or use imagePullSecrets.
Log AnalyticsEnable omsagent addon with config.logAnalyticsWorkspaceResourceID pointing to workspace.
Load BalancerAKS creates a managed Standard LB by default (loadBalancerSku: 'standard').
System PoolAt least one agent pool must have mode: 'System'. System pools run critical pods (CoreDNS, tunnelfront).

Paired WithConstraint
Virtual MachineAttach via storageProfile.osDisk or storageProfile.dataDisks. Disk must be in same region.
Availability ZonePremiumV2_LRS and UltraSSD_LRS require zone specification.
Premium SSD v2Cannot be used as OS disk (data disks only). Does not support host caching (ReadOnly/ReadWrite unavailable). Requires zonal VM deployment. Cannot mix with other storage types on SQL Server VMs.

Availability ZoneCannot combine with availability sets. Set zones: ['1'] (string array).
Managed Disk (Premium SSD)Not all VM sizes support Premium storage — check size docs for compatibility.
Managed Disk (UltraSSD)Requires additionalCapabilities.ultraSSDEnabled: true. Cannot enable on a running VM — requires stop/deallocate first.
Managed Disk (Premium SSD v2)Premium SSD v2 cannot be used as OS disk (data disks only). Does not support host caching (ReadOnly/ReadWrite unavailable). Requires zonal VM deployment. Cannot mix Premium SSD v2 with other storage types on SQL Server VMs.
Dedicated HostCannot specify both host and hostGroup.
Boot Diagnostics StorageCannot use Premium or ZRS storage. Use Standard_LRS or Standard_GRS.
CNI Overlay (AKS)DCsv2-series VMs are not supported with Azure CNI Overlay. Use DCasv5/DCadsv5 for confidential computing.
VM Scale Set
Paired WithConstraint
SubnetNetwork interfaces defined inline in virtualMachineProfile.networkProfile. Subnet must be in same region.
Load BalancerReference backend pool ID in NIC IP configuration.
Orchestration ModeFlexible is the modern default. Uniform requires upgradePolicy.
Availability ZoneSet zones: ['1', '2', '3'] for zone distribution. Cannot combine with availability sets.
