HAProxy (High Availability Proxy) is a reliable and high-performance open-source load balancer and reverse proxy server. It is widely used to distribute incoming traffic across multiple servers, optimize resource utilization, and improve application reliability and scalability. With its robust features, HAProxy is a key tool for achieving high availability and performance in web and application services.

Features of HAProxy:

• Load Balancing: Distributes traffic efficiently using algorithms such as round-robin, least connections, or IP hash.
• High Availability: Automatically reroutes traffic to healthy servers in case of server failures, ensuring uninterrupted service.
• SSL Termination: Offloads SSL encryption and decryption, improving backend server performance and simplifying certificate management.
• Traffic Management: Offers rate limiting, request queuing, and intelligent traffic routing based on URL, headers, or cookies.
• Logging and Monitoring: Provides detailed logs and integrates with monitoring tools like Prometheus and Grafana for real-time insights.
• Scalability: Handles millions of concurrent connections, making it ideal for high-demand environments.
• Security: Protects against threats with features like IP whitelisting, blacklisting, and DDoS mitigation.
