Changing Network

Last updated: 2024-09-11 16:52:28

This document describes how to change the network of TDSQL-C for MySQL in the console.
Overview
TDSQL-C for MySQL supports VPC, which is capable of offering a diversity of smooth services. On this basis, it provides the cluster network change feature to help you manage network connectivity with ease.
Notes
When the network is changed, all of the cluster's private IPs are automatically replaced with new ones. You should modify the client program accordingly in time.
You can specify the remaining validity period of the old IPs in the console. The period is 24 hours by default. If you set the period to 0 hours, the old IPs will be released immediately after the network is changed.
The new VPC and subnet should be in the region of the cluster.
Subnet description
A subnet is a logical network space in a VPC. You can create subnets in different AZs in the same VPC, which communicate with each other over the private network by default. Even if you select a subnet IP in another AZ in the region of the cluster, the network latency will not be increased because the actual business connection adopts nearby access.
