Buying a DataArts Migration Resource Group Incremental Package

Context

• When you create a DataArts Migration resource group incremental package, the system automatically creates a resource group required by real-time data integration jobs based on the specifications you set for the incremental package.
• When buying a DataArts Migration resource group incremental package (pay-per-use resource package), pay attention to the following:
  • When you buy a DataArts Migration resource group incremental package which is billed based on a pay-per-use package, the system does not automatically create a resource group for real-time processing migration jobs. Instead, you can use a resource group you have obtained on the DataArts Studio console for 745 hours each month within the validity period of the incremental package and in a specified region.
  • If you have one or more resource groups in a region, the duration quota of your resource package will be deducted first. Any usage beyond the quota will be billed in pay-per-use mode. (If a resource package is shared by multiple clusters, the available package duration may be insufficient in each subscription period.)

    For example, if you purchase a one-month package (745 hours/month) and two resources are associated with the package, 372.5 hours (about 15.5 days) can be allocated to each resource group within the one-month subscription. Any usage beyond the allocated hours will be billed in pay-per-use mode.

  • If you purchase a package and do not associate it with any resource group, the duration quota in the package will not be consumed and the validity period of the package will not be extended as well. Therefore, you are advised to make a plan before buying a package.
  • If you want to enjoy the preferential price of the yearly/monthly incremental package, you can buy a yearly/monthly incremental package and then buy a pay-per-use incremental package which is in the same region and has the same specifications as the yearly/monthly incremental package.
  • If you buy a pay-per-use incremental package and then a yearly/monthly incremental package in the same region and with the same specifications as the pay-per-use incremental package, the fees generated before you buy the yearly/monthly incremental package are charged in pay-per-use mode, and the subsequent fees are charged based on the yearly/monthly incremental package.
• You can locate a DataArts Studio instance, click More, and select View Packages to view your incremental packages.
