  1. Log on to the RDS console.
  2. On the Instances page, click Create Instance.
  3. Select Subscription or Pay-As-You-Go.
    • Subscription indicates prepayment, which means you need to pay the monthly or yearly price when creating an instance. This is cost-effective if you want to use the instance for one month or more.
    • Pay-As-You-Go indicates costs are automatically deducted from your Alibaba Cloud account by hour. You can release the instance at any time. This is cost-effective if you only want to use the instance temporarily.
  4. Select the instance configuration. The parameters are described as follows:
    • Basic configuration
      • Region and zone: Select the region and zone in which the instance is located. Some regions support both single-zone and multi-zone instances, while some regions support only single-zone instances.
        Note Products in different regions cannot intercommunicate through the intranet, and you cannot change the instance region after creating an instance. Therefore, exercise caution when you select the region.
