    Binding and Unbinding Resource Pack

    Last updated: 2023-11-09 14:35:01

      If you want to use a resource pack, you need to bind the resource pack after purchasing it. You can also unbind a resource pack that has been bound to clusters. This document describes how to bind or unbind a resource pack.
      Note:
      A resource pack can be bound to multiple serverless clusters, but a serverless cluster can only be bound to up to one compute resource pack and one storage resource pack.

      Prerequisites

      You have created a serverless cluster. For more information, see Creating Serverless Cluster.
      You have purchased a resource pack. For more information, see Purchasing Resource Pack.

      Binding a resource pack

      Scenario 1: Binding a resource pack when creating a serverless cluster

      1. Go to the purchase page and complete the Database Configuration settings.
      Parameter
      Description
      Instance Mode
      Select Serverless.
      Database Engine
      Select MySQL.
      Region
      Select a region for database deployment.
      Currently, the serverless mode is supported only in Guangzhou, Shanghai, Beijing, Nanjing, Hong Kong (China), Silicon Valley, Singapore, and Virginia regions. If you need to use it in other regions, submit a ticket for assistance.
      Source AZ
      Select an AZ for deployment. Specific AZs in the selected region are shown on the actual purchase page.
      Multi-AZ Deployment
      Currently, serverless instances don't support multi-AZ deployment.
      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 for MySQL instances only in the same VPC.
      Database Version
      MySQL 5.7 and 8.0 are supported.
      Compute Unit
      Select the upper and lower limits of the TDSQL-C compute unit (CCU), and the instance will be automatically and elastically scaled within the selected resource range.
      CCU is the computing and billing unit for the serverless mode. A CCU is approximately equal to 1 CPU core and 2 GB memory. The number of CCUs used in each billing cycle is the greater of the number of CPU cores used by the database and 1/2 of the memory size. For more information, see Compute Unit.
      Auto-Pause
      Configure the automatic pause time of the instance. If there is no connection to access the database within the set time, the instance will be automatically paused, with billing stopped.
      2. Complete the Specification Billing configuration and click Next.
      Note:
      Total serverless cluster fees = compute node fees + storage space fees = serverless computing power price number of CCUs + storage space price storage space
      
      Parameter
      Description
      Compute Billing Mode
      Select Resource Pack.
      The compute resource pack will be used preferably for the deduction of actual usage of pay-as-you-go products. When the pack is used up, the resource usage will be pay-as-you-go. Compute resource packs are deducted based on the actual CCU used per second. The resource pack mode is more cost-effective and flexible than the pay-as-you-go option.
      
      Compute Resource Pack
      You can bind all valid compute resource packs available in the selected region under the current account. If no resource pack is available, you can purchase a resource package first.
      Storage Billing Mode
      Select Resource Pack.
      ‌The storage resource pack will be used preferably for the deduction of actual usage of pay-as-you-go products. When the pack is used up, the resource usage will be pay-as-you-go. Storage resource packs are deducted based on the actual storage used per hour. The resource pack mode is more cost-effective and flexible than the pay-as-you-go option.
      
      Storage Resource Pack
      You can bind all valid storage resource packs available in the selected region under the current account. If no resource pack is available, you can purchase a resource package first.
      3. Select the number of clusters. You can batch purchase multiple clusters of the same specification. Then, click Next.
      4. Complete the Basic Info and Advanced Configuration settings, confirm the fees, and click Buy Now.
      Basic Info
      Parameter
      Description
      Cluster Name
      Name the instance now or later. It must contain less than 60 letters, digits, or symbols (-_.).
      Admin Username
      It is root by default.
      Password
      The password can contain 8–64 characters in at least three of the following character types: uppercase letters, lowercase letters, digits, and symbols ~!@#$%^&*_-+=|\\(){}[]:;'<>,.?/.
      Default Character Set
      UTF8, GBK, LATIN1, and UTF8MB4 are supported.
      Custom Port
      It is 3306 by default and can be customized.
      Advanced Configuration
      Parameter
      Description
      Security Group
      Select or create a security group.
      Parameter Template
      Select or create a parameter template.
      Table Name Case Sensitivity
      Select Case-Insensitive or Case-Sensitive.
      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.
      5. After the purchase is completed, you will be redirected to the cluster list. After the status of the cluster becomes Running, it can be used normally.
      Note:
      If only the compute resource pack is bound, the compute nodes of the serverless cluster will be deducted by using the bound compute resource pack, while the storage nodes will be billed on a pay-as-you-go basis.
      If only the storage resource pack is bound, the storage nodes of the serverless cluster will be deducted by using the bound storage resource pack, while the compute nodes will be billed on a pay-as-you-go basis.
      If both the compute and storage resource packs are bound, both the compute and storage nodes of the serverless cluster will be deducted by using the bound compute and storage resource packs.

      Scenario 2: Binding a resource pack to an existing serverless cluster

      Binding a resource pack to an existing serverless cluster in the resource pack list

      After purchasing a resource pack, you can bind it to an existing serverless cluster in the resource pack list.

      2. On the left sidebar, click Resource Pack to enter the resource pack management page.
      3. Find the target resource pack directly on the page or quickly filter it out in the search box on the right, and click Bind/Unbind in the Operation column.
      
      4. In the pop-up window, select a region, select one or more serverless clusters to which the resource pack is bound, and click OK.
