You can establish PrivateLink connections to access services on Alibaba Cloud. Network traffic does not traverse the Internet when PrivateLink is used. This prevents 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. Each region has multiple isolated locations known as zones. Each zone has its own independent power supply and network. The network latency between instances that are deployed in the same zone is lower than the network latency between instances that are deployed in different zones.
- 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.
