HAProxy

HAProxy is a high-availability, high-performance TCP/HTTP load balancer and proxying solution, offering ultra-low latency traffic routing, SSL termination, and robust health checking.

When to Use

• High-Performance Layer 4 & Layer 7 Load Balancing: Distributing millions of concurrent TCP/HTTP connections with low CPU overhead.
• TLS Termination & SSL Offloading: Offloading cryptographic handshakes at the edge before proxying to backend servers.
• Advanced Rate Limiting & Stick Tables: Tracking client IPs across sliding time windows to neutralize DDoS and brute force.
• Health Checking & Circuit Breaking: Detecting unhealthy backend servers and rerouting traffic instantaneously.
