Release 1.4.0 of the NGINX Ingress Controller for Kubernetes includes support for TCP and UDP load balancing and a "power of two choices" load-balancing algorithm (Random with Two Choices), extended Prometheus support, and easy development of custom Annotations.
NGINX and the “Power of Two Choices” Load-Balancing Algorithm
The Random with Two Choices load-balancing algorithm is NGINX's implementation of the "power of two choices" method. This biased random algorithm has been shown to be effective at balancing loads when each load balancer has an incomplete or delayed view of the traffic.
