+
+## 1. Choose Your Cloud Provider
+
+| Provider | Best For | Monthly Cost | CPU | RAM |
+|----------|----------|-------------|-----|-----|
+| **Linode** | Production, consistent performance | ~$240 | 8 cores | 32GB |
+| **DigitalOcean** | Development, quick setup | ~$336 | 8 vCPUs | 16GB |
+| **AWS + W&B** | ML workloads, GPU compute | ~$390 | 4 vCPUs + GPU | 16GB |
+
+## 2. Prerequisites Checklist
+

+
+## 3. Five-Minute Deployment
+
+### Step 1: Clone Repository
+```bash
+git clone https://github.com/EdwardPlata/accelerated-data-engineering.git
+cd accelerated-data-engineering
+```
+
+### Step 2: Configure Provider
+
+**Linode:**
+```bash
+cd terraform/linode
+cp terraform.tfvars.example terraform.tfvars
+# Edit terraform.tfvars with your credentials
+```
+
+**DigitalOcean:**
+```bash
+cd terraform/digitalocean
+cp terraform.tfvars.example terraform.tfvars
+# Edit terraform.tfvars with your credentials
+```
+
+**AWS + W&B:**
+```bash
+cd terraform/wandb
+cp terraform.tfvars.example terraform.tfvars
+# Edit terraform.tfvars with your credentials
+export AWS_ACCESS_KEY_ID="your-key"
+export AWS_SECRET_ACCESS_KEY="your-secret"
+```
+
+### Step 3: Deploy
+```bash
+terraform init
+terraform apply -auto-approve
+```
+
+### Step 4: Connect
+```bash
+# Get server IP
+SERVER_IP=$(terraform output -raw server_ip)
+
+# SSH into server
+ssh root@$SERVER_IP
+```
+
+### Step 5: Deploy SimpleDB
+```bash
+# On the server:
+cd /opt
+git clone https://github.com/EdwardPlata/accelerated-data-engineering.git
+cd accelerated-data-engineering/examples/database
+
+# Build
+mkdir -p build && cd build
+cmake -DCMAKE_BUILD_TYPE=Release ..
+make -j$(nproc)
+
+# Test
+./simple_db
+```
+
+## 4. Production Setup
+
+### Setup as System Service
+```bash
+# Create service file
+sudo tee /etc/systemd/system/simpledb.service > /dev/null <<EOF
+[Unit]
+Description=SimpleDB C++ Database
+After=network.target
+
+[Service]
+Type=simple
+User=root
+WorkingDirectory=/opt/accelerated-data-engineering/examples/database/build
+ExecStart=/opt/accelerated-data-engineering/examples/database/build/simple_db
+Restart=always
+StandardInput=tty-force
+StandardOutput=journal
+StandardError=journal
+
+[Install]
+WantedBy=multi-user.target
+EOF
+
+# Enable and start
+sudo systemctl daemon-reload
+sudo systemctl enable simpledb
+sudo systemctl start simpledb
+
+# Check status
+sudo systemctl status simpledb
+```
+
+### Enable Monitoring
+```bash
+# Access Grafana
+http://SERVER_IP:3000
+# Default: admin/admin
+
+# View metrics
+http://SERVER_IP:9090
+```
+
+## 5. Common Operations
+
+### View Logs
+```bash
+journalctl -u simpledb -f
+```
+
+### Restart Service
+```bash
+sudo systemctl restart simpledb
+```
+
+### Backup Data
+```bash
+tar czf simpledb-backup-$(date +%Y%m%d).tar.gz /data/simpledb
+```
+
+### Update Infrastructure
+```bash
+cd terraform/[provider]
+terraform plan
+terraform apply
+```
+
+### Destroy Infrastructure
+```bash
+terraform destroy
+```
+
+## 6. Performance Tuning
+
+### Check CPU Usage
+```bash
+htop
+```
+
+### Check Memory
+```bash
+free -h
+```
+
+### Check Disk I/O
+```bash
+iotop
+```
+
+### Optimize for Production
+```bash
+# Pin to specific CPUs
+taskset -cp 0-7 $(pidof simple_db)
+
+# Enable huge pages
+echo 1024 > /proc/sys/vm/nr_hugepages
+```
+
+## 7. Troubleshooting
+
+### Service Won't Start
+```bash
+# Check logs
+journalctl -u simpledb -n 50
+
+# Check if port is in use
+netstat -tuln | grep 9999
+
+# Test manually
+cd /opt/accelerated-data-engineering/examples/database/build
+./simple_db
+```
+
+### Can't Connect
+```bash
+# Check firewall
+ufw status
+
+# Test from local machine
+telnet SERVER_IP 9999
+nc -zv SERVER_IP 9999
+```
+
+### High Memory Usage
+```bash
+# Check process memory
+ps aux | grep simple_db | awk '{print $4, $11}'
+
+# Restart service
+sudo systemctl restart simpledb
+```
+

+- Linode: $10-20/month (Shared CPU)
+- DigitalOcean: $12-24/month (Basic Droplet)
+- Perfect for: Testing, development
+
+**Standard (Production):**
+- Linode: $240/month (Dedicated 8 cores)
+- DigitalOcean: $336/month (Dedicated CPU)
+- Perfect for: Production databases
+
+**High-Performance (ML/GPU):**
+- AWS: $390/month (GPU instance)
+- Perfect for: ML training, data analytics
+
+### Saving Money
+
+1. **Use reserved instances**: Save 30-50%
+2. **Auto-scale**: Scale down during off-hours
+3. **Monitor usage**: Track and optimize resources
+4. **Right-size**: Start small, scale as needed
+
+## Security Checklist
+
+- [ ] Change default passwords
+- [ ] Configure firewall (only allow your IP)
+- [ ] Disable root SSH login
+- [ ] Enable automatic security updates
+- [ ] Set up SSL certificates
+- [ ] Configure fail2ban
+- [ ] Regular backups
+- [ ] Monitor security logs

+### Cloud Providers
+
+1. **Linode** - Dedicated CPU instances for predictable performance
+2. **DigitalOcean** - Developer-friendly Dedicated Droplets
+3. **AWS with Weights & Biases** - GPU-accelerated ML workloads
+
+### Quick Start
+
+```bash
+# Navigate to provider directory
+cd terraform/linode  # or digitalocean, or wandb
