Server Load Balancer:Regions and zones in which GWLB 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. This way, if faults occur in a zone, other zones are not affected and continue to run as expected. 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, GWLB distributes requests across multiple zones and supports real-time disaster recovery. If one zone is down, GWLB distributes requests to other zones.
