Product Overview

Region and availability zone

This topic introduces the regions and availability zones supported by the message queue for Kafka to help you select a region and availability zone.

Basic concepts

Region refers to the physical area where VolcanoEngine data centers are located. VolcanoEngine divides different regions according to the geographical location of the data centers. After purchasing resources, you can not change the resource region.

Availability zone (AZ) is a physical area within the same region where the power and network infrastructure are independent of each other. If one availability zone fails, other availability zones within the same region will not be affected. Availability zones in different regions are completely isolated. Availability zones within the same region can be interconnected.

How to select a region

Considerations	Select plan
Geographic location	To reduce latency and improve access speed, we recommend that you purchase Kafka instance that is closest to your region.
Private network connectivity	If your service requires private network isolation, deploy across different regions. If your service requires private network communication, deploy within the same region.
Resource price	Resource prices may vary across regions. Choose based on your budget on the purchase page.

How to select an availability zone

Considerations	Select plan
Disaster recovery capability	If you need higher disaster recovery capability, deploy your business in different availability zones to ensure fault isolation and achieve cross-availability zone disaster recovery.
Network latency	If you need lower latency, we recommend that you purchase Kafka instances within the same availability zone.
