Yes.
You can deploy the active and standby nodes in an application to different regions. The primary node commonly provides services. When the application on a primary node fails, the application on a standby node can continue to provide services to your customers.
When deploying nodes, you can also choose to use the anti-affinity/mandatory anti-affinity policy for the cloud server group. Through the cloud server group function, the cloud servers are created on different hosts as much as possible/forcibly to improve the service reliability.
