How Can I Determine Which Region to Store My Data In?

When selecting a region, consider the following factors:

• Location

  Select a region close to you or your target users. This reduces network latency and improves access speed. However, Chinese mainland regions provide the same infrastructure, BGP network quality, as well as resource operations and configurations. If you or your target users are in the Chinese mainland, you do not need to consider differences in network latency when selecting a region.

  • If you or your target users are in the Asia Pacific region (excluding the Chinese mainland), select regions such as AP-Bangkok and AP-Singapore.
  • If you or your target users are in Africa, select the AF-Johannesburg region.
  • If you or your target users are in Europe, select the EU-Paris region.
• Relationships between cloud services

  If you use multiple cloud services together, note that:

  • ECS, RDS, and OBS cannot communicate with each other over a private intranet if they are not in the same region.
  • ECSs in different regions cannot be deployed on the same load balancer.
• Resource prices

  Resource prices may vary depending on different regions.
