Unimog - Cloudflare’s edge load balancer

What this post added

Introduced Unimog, an internal Layer 4 Load Balancer (L4LB) designed for Cloudflare's edge data centers. Unimog addresses the limitations of existing load balancing solutions by running on general-purpose servers, performing dynamic load balancing based on real-time server load measurements, supporting long-lived connections, managing virtual IP address ranges, and integrating tightly with DDoS mitigation systems using XDP. It improves reliability and operational efficiency by ensuring uniform load distribution across servers.
