System Requirements

For optimal Ruflo performance, ensure your Netcup VPS meets:

Minimum:

• OS: Ubuntu 22.04 LTS, Debian 12, or compatible Linux distribution
• CPU: 2 vCPU cores
• RAM: 4 GB
• Storage: 20 GB available space

Recommended:

• OS: Ubuntu 22.04 LTS (best compatibility)
• CPU: 4+ vCPU cores
• RAM: 8+ GB
• Storage: 50+ GB NVMe SSD
• Network: Stable internet connection

Setup Tips and Recommendations

1. Choose the Right Server Tier

• Development/Testing: VPS 500 or VPS 1000
• Small Production: VPS 1000 (8GB RAM minimum for agent operations)
• Medium Production: VPS 2000 (recommended for multi-agent setups)
• Large Production: VPS 4000 (for enterprise workloads)
• Maximum Performance: Root Server RS 4000 or RS 8000

2. Optimize for Ruflo Workloads

Memory Management:

• Ruflo agents consume significant memory for context and embeddings
• Monitor RAM usage with tools like htop or glances
• Consider swap configuration if using VPS 500 (4GB RAM)

Storage Configuration:

• Use NVMe storage for RVF vector databases (critical for performance)
• Allocate separate partitions for system, data, and logs
• Consider Local Block Storage add-on for large vector datasets

Network Configuration:

• Ensure stable DNS configuration for agent communication
• Configure firewall rules to allow required ports
• Use DDoS protection included with all Netcup servers

3. Use Docker for Production Deployments

Benefits:

• Isolated environments for different agent deployments
• Easy scaling and updates
• Resource management and limits
• Rollback capabilities

Docker Compose Example:

version: '3.8'

services:
  ruflo:
    image: ruflo/cli:full
    container_name: ruflo
    restart: unless-stopped
    volumes:
      - ./ruflo-data:/root/.ruflo
      - ./ruflo-agents:/root/.ruflo/agents
    environment:
      - NODE_ENV=production
      - ANTHROPIC_API_KEY=${ANTHROPIC_API_KEY}
    deploy:
      resources:
        limits:
          cpus: '4'
          memory: 8G

4. Security Best Practices

• API Key Management: Use environment variables, never hardcode in configuration files
• Firewall Configuration: Only expose necessary ports (default: no public ports needed)
• Regular Updates: Keep Ruflo updated with ruflo upgrade
• Backup Strategy: Regularly backup RVF data and agent configurations
• Access Control: Use SSH key-based authentication only

5. Monitoring and Maintenance

Essential Monitoring:

# Install monitoring tools
apt install -y htop glances nginx

# Check system resources
htop
glances

Health Checks:

• Monitor CPU and memory usage
• Track RVF storage size and performance
• Set up log rotation to prevent disk exhaustion
• Configure alerting for critical failures

6. Performance Tuning

Node.js Optimization:

# Set Node.js memory limit
export NODE_OPTIONS="--max-old-space-size=2048"

# Use production Node.js
node --max-old-space-size=2048 /path/to/ruflo

RVF Storage Tuning:

• RVF's HNSW indexing provides 150x-12,500x faster vector search
• Configure appropriate vector dimensions for your use case
• Use quantization for large datasets to reduce memory footprint

Common Use Cases

1. Multi-Agent Development

Deploy coordinated agent teams for complex workflows:

• Code generation and review agents
• Testing and QA automation
• Documentation generation
• Research and analysis teams

2. RAG-Powered Applications

Build retrieval-augmented generation applications:

• Knowledge base search
• Document analysis and summarization
• Intelligent chatbots with company data
• Research assistants with domain knowledge

3. Automated Workflows

Create autonomous workflow pipelines:

• CI/CD automation with intelligent decisions
• Data processing pipelines
• Automated testing and deployment
• Monitoring and alerting systems

4. Swarm Intelligence

Deploy distributed agent swarms:

• Parallel task execution
• Collaborative problem solving
• Load balancing across agents
• Fault-tolerant systems

Troubleshooting

Common Issues and Solutions

Issue: Out of Memory Errors

• Solution: Upgrade to VPS 2000+ (16GB RAM) or optimize agent memory usage

Issue: Slow Vector Search

• Solution: Ensure NVMe storage is being used for RVF data, check disk I/O performance

Issue: Agent Communication Failures

• Solution: Check firewall rules, ensure adequate network bandwidth, verify DNS configuration

Issue: High CPU Usage

• Solution: Review agent configurations, consider scaling to more vCPU cores or using Root Server

Issue: Storage Exhaustion

• Solution: Add Local Block Storage, implement log rotation, clean old RVF snapshots
