🎉 Load Balancing Tutorial

Load balancing is a critical technique for improving system performance and ensuring high availability in distributed applications. By distributing traffic across multiple servers, it prevents overload, enhances reliability, and optimizes resource utilization.

🌐 Key Concepts

• What is Load Balancing?
  A method to spread incoming network traffic across backend servers to maximize efficiency and minimize downtime.

  

• Common Algorithms

  • Round-Robin (轮询)
  • Least Connections (最少连接)
  • IP Hash (IP哈希)
  • Weighted Round-Robin (加权轮询)
  

• Benefits

  • 🚀 Improved Scalability
  • 🛡 Enhanced Fault Tolerance
  • 📈 Optimized Resource Utilization
  • 🌐 Global Traffic Distribution

🧰 Implementation Tools

• Nginx (https://cloud-image.ullrai.com/q/Nginx_Configuration/)
• HAProxy (https://cloud-image.ullrai.com/q/HAProxy_Interface/)
• AWS Elastic Load Balancer (https://cloud-image.ullrai.com/q/AWS_Load_Balancer/)

📚 Best Practices

1. Monitor server health with tools like Prometheus or Grafana.
2. Use sticky sessions for stateful applications (if needed).
3. Implement SSL termination at the load balancer for encryption.
4. Test failover scenarios regularly.
