Before you use the features of ApsaraDB MyBase, you must create instances on the hosts in your ApsaraDB MyBase dedicated cluster. The instances are created on the hosts based on the resource allocation policy that is selected.

Prerequisites

A host is added to an ApsaraDB MyBase for SQL Server dedicated cluster. For more information, see Create a host in an ApsaraDB MyBase for SQL Server dedicated cluster.

  5. Configure the following parameters.
    Create a MyBase for SQL Server instance
    Parameter Description
    Database Engine The database engine on which the instance runs. Select SQLServer. After an instance is created, you cannot change the database engine for the instance.
    Current Version The version of the database engine on which the instance runs. The following versions are supported:
    • SQL Server 2019 Enterprise Edition Always On
    • SQL Server 2017 Enterprise Edition Always On
    • SQL Server 2017 Enterprise Edition
    • SQL Server 2017 Standard Edition
    • SQL Server 2017 Web
    • SQL Server 2016 Enterprise Edition
    • SQL Server 2016 Standard Edition
    • SQL Server 2016 Web
    • SQL Server 2012 Enterprise Edition
    • SQL Server 2012 Standard Edition
    • SQL Server 2012 Web
    Edition The edition of the instance. The following editions are supported:
    • High Availability Edition
    • Basic Edition
    • Always On
    Note Configure this parameter based on Current Version. For more information, see ApsaraDB MyBase for SQL Server.
    Storage Type The storage type of the instance. Valid values:
    • Enhanced SSD (Recommended)
    • ESSD PL2 (Recommended)
    • ESSD PL3 (Recommended)
    Instance Type The type of the instance.
    Storage Capacity The storage of the instance.
    Deployment Method You can select Default Policy or Specified Host.
    • If you select Default Policy, Distribution Policy is set to Balance. This indicates that new database instances are preferentially created on hosts that have the most available resources.
    • If you select Specified Host, configure Primary Host and Secondary Host.
      Note
      • If you create an instance of Always On or the High-availability Edition, configure Primary Host and Secondary Host.
      • If you create an instance of the Basic Edition, configure only Primary Host.
    VSwitch The vSwitch to which the host is connected. If no option is available, create a vSwitch as instructed.
    Note This parameter is available only if you specify Default Policy as Deployment Method.
    Billing Method Select Pay-As-You-Go. This specifies that you are charged after you use the service.
    Note When you purchase hosts that use enhanced SSDs (ESSDs), you pay only for the computing fees. Therefore, when you create an instance on a host, you must pay for the used storage of ESSDs. A storage plan is a subscription plan for storage resources. If you subscribe to a storage plan in a region, you can use the storage plan to offset the used storage of the pay-as-you-go instances in the same region. This helps you reduce storage costs.
  6. Click Create Now. On the page that appears, complete the payment.
