Server Load Balancer:Regions and zones in which NLB is available

Last Updated:Jun 18, 2024

This topic describes the regions and zones in which Network Load Balancer (NLB) is available.

Regions and zones

Regions are geolocations of data centers. After you create a cloud resource, you cannot change the region in which the cloud resource is deployed. Each region has multiple isolated locations known as zones. Each zone has its own independent power supply and network.

Zones within the same region can communicate with each other over an internal network. Fault isolation can be enabled between zones. If one zone is down, other zones in the same region are not affected. Regions are independent of each other. Zones of different regions are isolated from each other. However, low-latency connections can be established between zones within the same region.

地域与可用区

To provide more stable load balancing services, NLB can distribute network traffic across specified zones to implement disaster recovery. If one zone is down, other zones take over to maintain service availability.
