当我对等不同区域的两个 VPC 时,流量是否会穿过 public 互联网?

When I peer two VPCs in different regions does the traffic traverse through the public internet?

我正在寻找各种方法来连接不同区域的两个 VPC,而无需通过 public 互联网传输流量。

不,它不会通过 public 互联网。来自 docs:

Traffic always stays on the global AWS backbone, and never traverses the public internet, which reduces threats, such as common exploits, and DDoS attacks.
