# Infrastructure Status Analysis

## Current Cluster Status Breakdown

### Summary
- **Total Clusters**: 25 (24 deployment regions + 1 admin region)
- **Ready (Succeeded)**: 1/25 (4%)
- **Creating**: 0
- **Failed**: 7/25 (28%)
- **Canceled**: 16/25 (64%)
- **Missing**: 1/25 (4%)

### Status Breakdown

#### ✅ Ready Clusters (1)
- **az-p-we-aks-main** (West Europe - Admin region)
  - Status: Succeeded
  - Power State: Running
  - Purpose: Administrative cluster (no validators/sentries)

#### ❌ Failed Clusters (7)
Failed clusters are in a terminal error state and cannot be updated:

1. **az-p-bc-aks-main** (Belgium Central) - Power: Deallocated
2. **az-p-cc-aks-main** (Canada Central) - Power: Deallocated
3. **az-p-fc-aks-main** (France Central) - Power: Deallocated
4. **az-p-gwc-aks-main** (Germany West Central) - Power: Deallocated
5. **az-p-noe-aks-main** (Norway East) - Power: Deallocated
6. **az-p-sc-aks-main** (Spain Central) - Power: Deallocated
7. **az-p-ukw-aks-main** (UK West) - Power: Deallocated

**Common Issues**:
- Clusters stopped during creation/update
- Terraform errors: "Managed Cluster is in stopped state, no operations except for start are allowed"
- Resource allocation failures
- Quota limitations

#### ⚠️ Canceled Clusters (16)
Canceled clusters were interrupted during deployment:

1. **az-p-ae-aks-main** (Australia East)
2. **az-p-ase-aks-main** (Australia Southeast)
3. **az-p-ci-aks-main** (Central India)
4. **az-p-ea-aks-main** (East Asia)
5. **az-p-in-aks-main** (Italy North)
6. **az-p-je-aks-main** (Japan East)
7. **az-p-jw-aks-main** (Japan West)
8. **az-p-kc-aks-main** (Korea Central)
9. **az-p-ks-aks-main** (Korea South)
10. **az-p-mc-aks-main** (Mexico Central)
11. **az-p-ne-aks-main** (North Europe)
12. **az-p-pc-aks-main** (Poland Central)
13. **az-p-si-aks-main** (South India)
14. **az-p-sea-aks-main** (Southeast Asia)
15. **az-p-sn-aks-main** (Switzerland North)
16. **az-p-uks-aks-main** (UK South)

**Common Issues**:
- Deployment was canceled/interrupted
- Terraform process was stopped
- User cancellation
- Timeout during creation

### Root Cause Analysis

#### Primary Issues:

1. **Stopped State Problem**:
   - Clusters were stopped during Terraform updates
   - Error: "Managed Cluster is in stopped state, no operations except for start are allowed"
   - Terraform cannot update stopped clusters
   - Clusters need to be started before updates

2. **Deployment Interruption**:
   - Terraform deployment was interrupted/canceled
   - Multiple deployment attempts left clusters in inconsistent states
   - State lock issues prevented proper reconciliation

3. **Quota/Limit Issues**:
   - vCPU quota constraints
   - Resource allocation failures
   - AKS surge node consumption

4. **State Mismatch**:
   - Clusters exist in Azure but not in Terraform state
   - Import issues prevented proper state management
   - Deleted clusters not properly removed from state

### Solutions Needed

#### Immediate Actions:

1. **Clean Up Failed Clusters**:
   ```bash
   # Delete failed clusters so they can be recreated
   ./scripts/deployment/delete-bad-clusters.sh
   ```

2. **Start Stopped Clusters** (if any):
   ```bash
   # Start any stopped clusters
   ./scripts/deployment/start-stopped-clusters.sh
   ```

3. **Re-run Terraform**:
   ```bash
   cd terraform/well-architected/cloud-sovereignty
   terraform apply -parallelism=128 -auto-approve
   ```

4. **Clean Up Canceled Clusters**:
   - Canceled clusters may need manual deletion
   - Or wait for automatic cleanup

#### Long-term Solutions:

1. **Fix Terraform Configuration**:
   - Prevent cluster stopping during updates
   - Add lifecycle rules to prevent accidental stops
   - Improve error handling

2. **Improve Deployment Process**:
   - Use blue/green deployment for node pool updates
   - Implement proper state management
   - Add rollback capabilities

3. **Quota Management**:
   - Request quota increases if needed
   - Optimize resource allocation
   - Monitor quota usage

### Current Workarounds

1. **West Europe Cluster Ready**: Can proceed with deployment to this cluster
2. **Scripts Ready**: All deployment scripts are ready to use when clusters are available
3. **Infrastructure Foundation**: Resource groups and networking are mostly created

### Next Steps

1. Delete failed/canceled clusters
2. Re-run Terraform deployment
3. Wait for clusters to become ready
4. Re-execute next steps once more clusters are ready

### Monitoring

- **Terraform Log**: `/tmp/terraform-apply-unlocked.log`
- **Cluster Status**: `az aks list --query '[?contains(name, "az-p-")].{name:name, state:provisioningState}' -o table`
- **Dashboard**: `./scripts/deployment/deployment-dashboard.sh`
