Database Engine | Select MySQL. |
Region | Select a region for database deployment. |
Source AZ | Select an AZ for deployment. Specific AZs in the selected region are shown on the actual purchase page. |
Multi-AZ Deployment | Select whether to enable multi-AZ deployment. If you enable it, the replica AZ option will appear. |
Replica AZ | It is disabled by default and can be selected after multi-AZ deployment is enabled. |
Transfer Linkage | It is "High IO" by default. |
Network | For performance and security considerations, only VPC network is supported currently. CVM instances can communicate with TDSQL-C instances only in the same VPC. 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 in another AZ in the same region, the network latency will not be increased because the actual business connection adopts nearby access. |
Database Version | MySQL 5.7 and 8.0 are supported. |
Compute Instance (read/write) | Select the compute specifications of the read-write instance. Only one read-write instance can be configured. |
Compute Instance (read-only) | Select the compute specifications of the read-only instance. You need to select at least two read-only instances to ensure that the cluster is highly available. After the cluster is created, you can expand the read capability of the cluster by adding up to 15 read-only instances. |
Auto-Renewal | Auto-renew the device monthly upon expiration if your account has sufficient balance |
Compute Billing Mode | Monthly subscription and pay-as-you-go billing are supported. |
Storage Billing Mode | Pay-as-you-go billing is supported, which means you don't need to specify a storage option when you make a purchase. TDSQL-C for MySQL is billed by the actual storage used per hour. Monthly subscription billing is supported, which means you need to purchase monthly-subscribed storage space now (billed in the entirety regardless of whether it is used up). |
