## 📋 Remaining Tasks

### 🔴 High Priority (Required for Functionality)

#### 1. Configure Besu Nodes (5 VMs)
**Status**: Pending  
**Requires**: VPN/Bastion access  
**Effort**: ~15 minutes per VM

**Backend VMs:**
```
Region        IP          VM Name                    Command
─────────────────────────────────────────────────────────────────
centralus     10.3.1.4    az-p-cus-vm-besu-node-0    ssh besuadmin@10.3.1.4
eastus        10.1.1.4    az-p-eus-vm-besu-node-0     ssh besuadmin@10.1.1.4
eastus2       10.4.1.4    az-p-eus2-vm-besu-node-0   ssh besuadmin@10.4.1.4
westus        10.2.1.4    az-p-wus-vm-besu-node-0    ssh besuadmin@10.2.1.4
westus2       10.5.1.4    az-p-wus2-vm-besu-node-0   ssh besuadmin@10.5.1.4
```

**Steps:**
```bash
# For each VM (via VPN/Bastion)
ssh besuadmin@<ip>
wget <setup-script-url>
chmod +x setup-besu-node.sh
sudo ./setup-besu-node.sh besu-node 0 <region>
sudo systemctl status besu.service
```

#### 2. Cross-Region Connectivity
**Status**: Pending  
**Requires**: Network infrastructure decision  
**Effort**: 1-4 hours

**Problem**: Nginx proxy (West Europe) needs to reach backend VMs (US regions) via private IPs.

**Options:**
- **Option A**: Azure VPN/ExpressRoute (Recommended for production)
- **Option B**: Cloudflare Tunnel on backend VMs
- **Option C**: Azure Private Link

#### 3. Besu Genesis Configuration
**Status**: Pending  
**Requires**: Genesis file  
**Effort**: ~30 minutes

**Steps:**
1. Generate/obtain genesis file for Chain ID 138
2. Upload to Azure Storage or Key Vault
3. Configure on all backend VMs
4. Restart Besu services

### 🟡 Medium Priority (Important for Production)

#### 4. Security Hardening
- Review and tighten NSG rules
- Configure Key Vault network ACLs
- Enable Azure Security Center
- Review access policies
- Rotate secrets if needed

#### 5. Monitoring Setup
- Configure Log Analytics queries
- Set up alerts (VM availability, Besu health, Nginx status)
- Create dashboards in Azure Monitor

#### 6. Backup Configuration
- Configure backup policies for VMs
- Test backup and restore procedures
- Document recovery procedures

### 🟢 Low Priority (Nice to Have)

#### 7. Validator Keys Configuration (If Applicable)
- Generate validator keys
- Store in Key Vault
- Configure Besu to use keys

#### 8. Performance Testing
- Load test RPC endpoints
- Test WebSocket connections
- Verify load balancing
- Optimize configurations

#### 9. Documentation
- Operational procedures
- Runbooks for common issues
- Disaster recovery procedures
- Architecture diagrams

## 🎯 Immediate Action Plan

### Step 1: Establish VPN/Bastion Access
- Set up VPN connection or Bastion host
- Test connectivity to backend VMs
- Verify SSH access

### Step 2: Configure Besu Nodes
- SSH to each backend VM
- Run setup script
- Verify Besu is running
- Test RPC endpoints locally

### Step 3: Implement Connectivity
- Choose connectivity solution
- Implement chosen solution
- Test connectivity from Nginx to backend VMs
- Update Nginx configuration if needed

### Step 4: Configure Genesis
- Generate/obtain genesis file
- Upload to storage/Key Vault
- Configure on all backend VMs
- Restart services

## 📊 Progress Tracking

| Category | Progress | Status |
|----------|----------|--------|
| Infrastructure | 100% | ✅ Complete |
| Services | 50% | ⏳ In Progress |
| Connectivity | 0% | ⏳ Pending |
| Configuration | 0% | ⏳ Pending |
| Security | 0% | ⏳ Pending |

## 🚀 Quick Start

### Test Current Setup
```bash
# Verify endpoint
curl https://rpc.d-bis.org/health
# Should return: "healthy"
```

### Configure First Besu Node (Example: East US)
```bash
# Via VPN/Bastion
ssh besuadmin@10.1.1.4
wget <setup-script-url>
chmod +x setup-besu-node.sh
sudo ./setup-besu-node.sh besu-node 0 eastus
sudo systemctl status besu.service
```

### Check Services
```bash
# Nginx Proxy
ssh besuadmin@20.160.58.99
sudo systemctl status cloudflared
sudo systemctl status nginx

# Backend VM (via VPN/Bastion)
ssh besuadmin@10.1.1.4
sudo systemctl status besu.service
docker ps
```
