# Deployment Strategy Clarification

## Current Configuration

### West Europe (Primary Region)
- **AKS Cluster**: 1 cluster (az-p-we-aks-main)
- **System Nodes**: 3 × Standard_D2s_v3 (6 vCPUs)
- **Validators**: 1 × Standard_B2s (2 vCPUs) - Planned
- **Total**: 8 vCPUs (within 10 limit)

### Cloud for Sovereignty (37 Regions)
- **Foundation**: ✅ Deployed (resource groups, VNets, Key Vaults)
- **AKS Clusters**: ❌ Not deployed (deploy_aks_clusters = false)
- **Validators**: ❌ Not configured

## Deployment Options

### Option 1: 5 Validators in West Europe
**Configuration**:
- 5 × Standard_B2s = 10 vCPUs
- **Issue**: Exceeds 10 vCPU limit (need quota increase)
- **Cost**: ~$75/month
- **Location**: Single region (West Europe)

### Option 2: 1 Validator per Region (5 Regions)
**Configuration**:
- 5 regions × 1 validator = 5 × Standard_B2s = 10 vCPUs total
- **Requirements**:
  - Deploy AKS clusters in 5 regions
  - Each region needs quota for 2 vCPUs
  - **Cost**: ~$75/month (5 × $15/month)
- **Regions**: Could use West Europe, North Europe, UK South, France Central, Germany West Central

### Option 3: Validators as Pods (No Quota Needed)
**Configuration**:
- Deploy Besu validators as pods on existing system nodes
- **Advantages**:
  - No additional quota needed
  - Can deploy immediately
  - Can deploy in multiple regions (if AKS clusters exist)
- **Cost**: $0 additional (uses existing nodes)

## Recommended Strategy

### Phase 1: Immediate (No Quota Needed)
- Deploy Besu validators as pods in West Europe
- Uses existing 6 vCPUs from system nodes
- Can deploy multiple validators as pods

### Phase 2: Regional Expansion (After Quota/Infrastructure)
- Deploy AKS clusters in priority regions
- Deploy 1 validator per region (or as pods)
- Scale based on requirements

### Phase 3: Production (Full Deployment)
- Deploy dedicated validator node pools
- Use Standard_B2s or Standard_B2ms
- Deploy across multiple regions for redundancy

## Questions to Clarify

1. **How many validators?**
   - 5 validators total?
   - Or 1 validator per region across 5 regions?

2. **Which regions?**
   - All in West Europe?
   - Or distributed across multiple regions?

3. **Deployment method?**
   - Dedicated node pools (need quota)?
   - Or as pods on existing nodes (no quota)?

4. **Timeline?**
   - Immediate (pods)?
   - Or after quota increase (node pools)?
