# Phase 1: Todo List

## ✅ Completed Tasks (6)

- [x] **Infrastructure Deployment** - Deploy 104 resources (VMs, networking, storage, monitoring)
- [x] **Nginx Configuration** - Configure Nginx backend with 5 backend VM IPs
- [x] **Cloudflare Tunnel** - Set up Cloudflare Tunnel - running, connected, DNS updated
- [x] **DNS Configuration** - Configure DNS (rpc.d-bis.org → Cloudflare Tunnel)
- [x] **SSL/TLS** - Enable SSL/TLS (automatic via Cloudflare)
- [x] **Endpoint Verification** - Verify endpoint: https://rpc.d-bis.org/health → "healthy"

## 📋 Pending Tasks (13)

### 🔴 High Priority - Required for Functionality (8 tasks)

#### Besu Node Configuration (5 VMs)
- [ ] **Besu Node - Central US** - Configure Besu node on Central US VM (10.3.1.4, az-p-cus-vm-besu-node-0) - requires VPN/Bastion
- [ ] **Besu Node - East US** - Configure Besu node on East US VM (10.1.1.4, az-p-eus-vm-besu-node-0) - requires VPN/Bastion
- [ ] **Besu Node - East US 2** - Configure Besu node on East US 2 VM (10.4.1.4, az-p-eus2-vm-besu-node-0) - requires VPN/Bastion
- [ ] **Besu Node - West US** - Configure Besu node on West US VM (10.2.1.4, az-p-wus-vm-besu-node-0) - requires VPN/Bastion
- [ ] **Besu Node - West US 2** - Configure Besu node on West US 2 VM (10.5.1.4, az-p-wus2-vm-besu-node-0) - requires VPN/Bastion

#### Infrastructure & Configuration
- [ ] **Cross-Region Connectivity** - Implement cross-region connectivity (Nginx proxy needs to reach backend VMs) - Choose: VPN/ExpressRoute, Cloudflare Tunnel on backend VMs, or Azure Private Link
- [ ] **Besu Genesis Configuration** - Configure Besu genesis file for Chain ID 138 - Generate/obtain genesis file, upload to storage/Key Vault, configure on all backend VMs

### 🟡 Medium Priority - Important for Production (3 tasks)

- [ ] **Security Hardening** - Review/tighten NSG rules, configure Key Vault network ACLs, enable Azure Security Center, review access policies, rotate secrets
- [ ] **Monitoring Setup** - Configure Log Analytics queries, set up alerts (VM availability, Besu health, Nginx status), create dashboards in Azure Monitor
- [ ] **Backup Configuration** - Configure backup policies for VMs, test backup/restore procedures, document recovery procedures

### 🟢 Low Priority - Nice to Have (3 tasks)

- [ ] **Validator Keys Configuration** - Configure validator keys (if applicable) - Generate validator keys, store in Key Vault, configure Besu to use keys
- [ ] **Performance Testing** - Load test RPC endpoints, test WebSocket connections, verify load balancing, optimize configurations
- [ ] **Documentation** - Complete documentation - Operational procedures, runbooks for common issues, disaster recovery procedures, architecture diagrams

## 📊 Progress Summary
