      This document describes how to create a Provisioned Resource cluster in the TDSQL-C for MySQL console. For the creation of a serverless cluster, see Creating Serverless Cluster.

      Prerequisite

      To make a purchase, you need to complete identity verification first. For more information, see Identity Verification Guide.

      Directions

      1. Log in to the purchase page and complete the settings of Database Configuration and Billing Mode.
      Parameter
      Description
      Instance Mode
      Select Provisioned Resource.
      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).
      Note:
      If your desired instance specification is sold out, you can click Do you need it? and the pop-up window will display instances of the same specification in other AZs. If none of them meet your requirements, submit a ticketfor assistance.
      
      Monthly subscribed storage space can be purchased only after you select the monthly subscription billing mode.
      For more information on how to select an appropriate billing mode for storage space, see Selecting Billing Mode for Storage Space.
      2. Complete the Basic Info and Advanced Configuration settings, select the Validity Period and Quantity, confirm the fees, and click Buy Now.

      Project
      Specify a project for the cluster to be created.
      Alarm Policy
      Select or create an alarm policy.
      Tag
      Add a tag to facilitate resource categorization and management.
      Terms and Conditions
      Read and indicate your consent to the terms and conditions.
      Note:
      When you hover over Configuration Fees, the details such as computing fees and storage fees will be displayed.
      
      Quantity
      Pay-as-you-go: You can purchase up to ten TDSQL-C for MySQL clusters in each AZ. If you need more, submit a ticket for assistance.
      Monthly subscription: You can purchase an unlimited number of clusters.
      When the amount of data stored in a cluster exceeds its maximum storage space, the cluster can only read but not write data. In this case, you can choose to delete redundant data or upgrade the specification.
