This post introduces 'Dynamic Steering' for Cloudflare Load Balancing, an enterprise-only feature that intelligently directs traffic to the fastest origin pool for a given Cloudflare region. It addresses the limitations of manual geo-steering by introducing a system to measure and distribute origin pool speed data globally. The post details the technical implementation, including the use of Exponential Weighted Moving Average (EWMA) to calculate pool Round Trip Time (RTT) and a custom in-house key-value store for efficient data propagation across Cloudflare's network.
