GKE Mixed-Protocol Load Balancers Reach General Availability
Google Kubernetes Engine has reached general availability for mixed-protocol Services of type LoadBalancer. This feature allows a single IP address to handle simultaneous TCP and UDP traffic for both external and internal Network Load Balancers across IPv4, IPv6, and dual-stack environments. This resolves prior traffic routing errors and is available in GKE version 1.36.2-gke.1498000 and later, benefiting users managing diverse network traffic patterns.
