Terraform State Boundaries

Terraform state is treated as a platform engineering control.

Why it matters

State separation reduces blast radius, clarifies ownership, and prevents unrelated changes from mutating critical platform components.

Key boundaries

Root Ownership
platform-networking Hub/spoke, firewall, FortiGate, VPN, BGP, shared route control
platform-management Management VM and AWX/control-plane resources
platform-aks Private AKS, ACR integration, workload identity, monitoring, AKS-specific egress
platform-avd AVD session hosts, FSLogix, secure workspace resources
aws-branch AWS branch and Cisco/AWS-side resources
governance and platform-shared Policy, monitoring, backup, and shared platform services
