Can the cloud server CVM and TencentDB for Redis be connected using the intranet if they are in different availability zones under the same private network?

Yes, the cloud server (CVM) and TencentDB for Redis can be connected using the intranet even if they are in different availability zones under the same private network.

In Tencent Cloud's architecture, resources within the same VPC (Virtual Private Cloud) can communicate over the intranet regardless of their availability zone placement. This ensures low-latency and secure connections without traversing the public internet.

For example:

1. You have a CVM deployed in Availability Zone A and a TencentDB for Redis instance in Availability Zone B, both under the same VPC.
2. By configuring the CVM to use the intranet IP of the Redis instance, they can communicate directly via the private network.

To achieve this:

• Ensure the CVM and Redis are in the same VPC.
• Use the intranet IP address of the TencentDB for Redis instance when connecting from the CVM.
• Verify that the security group and network ACL rules allow traffic between the two resources.

Tencent Cloud's Private Network (VPC) and TencentDB for Redis are designed to support such cross-zone intranet communication, enabling efficient and secure deployments.
