You can establish PrivateLink connections to access services on Alibaba Cloud. Network traffic does not traverse the Internet when PrivateLink is used. This avoids security risks over the Internet.

Regions and zones

A region is a geographic location where Alibaba Cloud data centers are deployed. After a resource is created, you cannot change the region of the resource. Zones are physical locations with independent power supplies and networks within a region. The network latency between instances within the same zone is lower than that between different zones.

Zones within the same region can access each other over the internal network. When a zone is down, other zones are not affected. We recommend that you choose a deployment method based on your business requirements for disaster recovery and network latency.
  • If your application requires high disaster recovery capabilities, we recommend that you deploy instances in different zones of the same region.
  • If your application requires low latency, we recommend that you deploy instances within the same zone.
