To access services through ALB Ingress in an ACK cluster or ACK Serverless cluster, the cluster must reside in an ALB-supported region and zone. This topic lists the regions and zones (AZs) supported by ALB.
Regions and zones
A region is a geographic area with Alibaba Cloud data centers. Cloud resources cannot move between regions. Each region has multiple zones — isolated locations with independent power and networking.
Zones in the same region communicate over the internal network with low latency. Faults in one zone do not affect other zones.
ALB distributes requests across zones. If a zone goes down, ALB automatically routes requests to healthy zones.
