Buying a DataArts Migration Incremental Package

Context

• When buying a CDM incremental package (pay-per-use resource package), pay attention to the following:

  • When you buy a CDM incremental package which is billed based on a pay-per-use package, the system does not automatically create a CDM cluster. Instead, you can use a CDM cluster you have obtained on the DataArts Studio console for 745 hours each month within the validity period of the incremental package.
  • The pay-per-use resource package can only be used to create a CDM cluster on the DataArts Studio console but not a CDM cluster on the CDM console. To create a CDM cluster on the CDM console, you must buy a discount package (pay-per-use resource package) on the CDM console.
  • A discount package can be used by one or more qualified CDM clusters in the specified region. Any resource usage beyond the package quotas is billed based on a pay-per-use basis.

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

  • If you purchase a package and do not associate it with any CDM clusters, the 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.
• You can buy a CDM cluster by buying an incremental package on the DataArts Studio console. You can also buy a CDM cluster directly on the CDM console. The two methods differ in the following ways:
  1. Package billing: CDM clusters purchased on the DataArts Studio console can be billed only by packages purchased on the DataArts Studio console. CDM clusters purchased on the CDM console can be billed only by discount packages purchased on the CDM console.
  2. Permission control: Permissions of the CDM clusters purchased on the DataArts Studio console are managed based on the DataArts Studio permission system. Permissions of the clusters purchased on the CDM console are managed based on the CDM permission system.
  3. Application scenarios: Clusters purchased on the DataArts Studio console are isolated by workspace and can be used only in associated workspaces. Clusters purchased on the CDM console do not support workspace-level resource isolation and can be used in all DataArts Studio workspaces.

  This section uses the first method as an example, which is recommended.

Buying a Pay-Per-Use CDM Cluster

If you buy a pay-per-use incremental package, the system automatically creates a CDM cluster based on the specifications you select.

1. Locate an enabled instance and click Buy.

2. On the displayed page, set parameters based on Table 1.

   Table 1 Parameters for the CDM incremental package

   Parameter	Description
   Package	Select DataArts Migration.
   Billing Mode	Select Pay per Use.
   AZ	When you buy your first DataArts Studio instance or incremental package, you can select any available AZ. When you buy another DataArts Studio instance or incremental package, determine whether to select the same AZ as the first instance or incremental package based on your DR and network latency demands. If your application requires good DR capability, select an AZ different from that of the first instance or incremental package in the same region. If your application requires a low network latency between instances, select the same AZ as the first instance or incremental package. For details, see Regions and AZs.
   Workspace	Select the workspace where the CDM incremental package is to be used. A CDM cluster can be used in a workspace only after the CDM cluster is associated with the workspace.
   Enterprise Project	If the CDM cluster is associated with multiple workspaces, select an enterprise project for the CDM cluster.
   Cluster Name	Customize the cluster name.
   Instance Type	The following CDM cluster flavors are available: cdm.large: the large flavor with 8 vCPUs and 16 GB of memory. The maximum and assured bandwidths are 3 Gbit/s and 0.8 Gbit/s. Up to 16 jobs can be executed concurrently. cdm.xlarge: the ultra-large flavor with 16 vCPUs and 32 GB of memory. The maximum and assured bandwidths are 10 Gbit/s and 4 Gbit/s. Up to 32 jobs can be executed concurrently. This flavor is suitable for migrating terabytes of data that requires a bandwidth of 10GE. cdm.4xlarge: the 4x ultra-large flavor with 64 vCPUs and 128 GB of memory. The maximum and assured bandwidths are 40 Gbit/s and 36 Gbit/s. Up to 128 jobs can be executed concurrently.
   VPC	VPC, subnet, and security group to which the CDM cluster in the DataArts Studio instance belongs. If you want to connect the DataArts Studio instance or CDM cluster to a cloud service such as GaussDB(DWS), MRS, and RDS, ensure that the CDM cluster can communicate with the cloud service. If the CDM cluster and the cloud service are in the same region, VPC, subnet, and security group, they can communicate with each other by default. If the CDM cluster and the cloud service are in the same VPC but in different subnets or security groups, you must configure routing rules and security group rules. For details about the operations on VPCs, subnets, and security groups, see Virtual Private Cloud User Guide. NOTE: After the CDM cluster is created, its VPC, subnet, and security group cannot be changed. Set them carefully. You can select a VPC subnet shared by the VPC owner when you buy a CDM cluster. Through VPC subnet sharing, you can easily configure and manage multiple accounts' resources at low costs. For details about how to share a VPC subnet, see VPC Sharing.
   Subnet
   Security Group
   IPv6 Dual Stack	If you enable this function, both private IPv4 and IPv6 addresses can be used to access the cluster. NOTE: If you enable this function, you can only select subnets for which IPv6 CIDR blocks are enabled. If IPv6 CIDR blocks are disabled for the subnet you want to select, enable IPv6 CIDR blocks for the subnet in the VPC service. IPv6 dual stack can be enabled for private IP addresses, but not for public IP addresses.

   

   You cannot modify the specifications of an existing cluster. If you need higher specifications, create another cluster.

3. Click Buy Now, confirm the specifications, and click Next.
4. Go to the corresponding workspace to view the CDM cluster you have purchased.

Buying a Pay-per-Use Package

If you want to enjoy the favorable price of a package, you can buy an incremental package billed by package and then buy a pay-per-use incremental package which is in the same region and has the same specifications as the incremental package billed by package.

1. Locate an enabled instance and click Buy.
2. Access the page for buying a DataArts Studio incremental package and set the following parameters:
   1. Select DataArts Migration for Package.
   2. Select Pay-per-Use Package for Billing Mode.
   3. Specify a validity period in Required Duration for the package.
   4. Enter the number of packages you want to buy in Quantity. For example, if you set Required Duration to 1 month and Quantity to 2, you will have a 1490-hour quota in one month.
3. Click Buy Now, confirm the specifications, and click Next.
4. After you buy this package, the system will not automatically create a CDM cluster. You need to buy a pay-per-use incremental package in the same region and with the same specifications as this package by following the instructions in Buying a Pay-Per-Use CDM Cluster. Then you can enjoy the favorable price of this package.
