Azure Enterprise Infra Planner

Azure Enterprise Infra Planner

When to invoke

Activate this skill when user wants to:

• Plan enterprise Azure infrastructure from a workload or architecture description
• Architect a landing zone, hub-spoke network, or multi-region topology
• Design networking infrastructure: VNets, subnets, firewalls, private endpoints, VPN gateways
• Plan identity, RBAC, and compliance-driven infrastructure
• Generate Bicep or Terraform for subscription-scope or multi-resource-group deployments
• Plan disaster recovery, failover, or cross-region high-availability topologies

Quick Reference

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.

### Details
Topology, identity and network design, and generated Bicep or Terraform.

### Validation
- <check performed>: <result and evidence>

Quality gate

• The design states its Well-Architected trade-offs.
• Generated infrastructure code passes a lint or validation pass.
• The output follows ## Output template exactly.
• Every reported check was performed and its evidence is shown.
• Irreversible Azure actions were confirmed with the user first.
