Firmy, które używają GitHub Load Balancer Director
GLB Director is a Layer 4 load balancer which scales a single IP address across a large number of physical machines while attempting to minimise connection disruption during any change in servers. GLB Director does not replace services like haproxy and nginx, but rather is a layer in front of these services (or any TCP service) that allows them to scale across multiple physical machines without requiring each machine to have unique IP addresses.
