Server Load Balancer:Supported regions and zones

Last Updated:Aug 23, 2023

This topic describes the regions and zones that are supported by Application Load Balancer (ALB).

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. A region consists of multiple isolated locations known as zones. Each zone has its own independent power supply and networks.

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

To provide more stable and reliable load balancing services, ALB distributes requests across multiple zones and supports real-time disaster recovery. If one zone is down, ALB distributes requests to other zones.
