Eliminating Cross-Zone Kubernetes Traffic With High Availability Zonal Load Balancing (HAZL)

April 23, 2024

Watch this video for a hands-on technical walkthrough of High Availability Zonal Load Balancing (HAZL), a new load balancer in Buoyant Enterprise for Linkerd (BEL) that can eliminate expensive cross-zone Kubernetes traffic without sacrificing overall reliability incurred by Kubernetes' native Topology-aware Hints feature—even for multi-cluster traffic. HAZL can drop cross-zone cloud spend by over 60% without impacting overall system availability.
