If a large number of data integration nodes must be concurrently run, you need exclusive computing resource groups to make sure that data is transmitted in a fast and reliable manner. In this case, you can use exclusive resource groups for Data Integration.

Limits

Exclusive resource groups are deployed in VPCs of Alibaba Cloud. If your data store is deployed on the classic network of Alibaba Cloud, the exclusive resource groups cannot access the data store. In this case, we recommend that you bind the data store to a VPC.

Scenarios

  • The resources in exclusive resource groups for Data Integration can be scheduled at any time to ensure the data output of nodes. We recommend that you use exclusive resource groups for Data Integration for production nodes.
  • You must use exclusive resource groups in scenarios in which a large number of data integration nodes are run and data output is required as early as possible.
  • If the data store is deployed on the Internet or in a VPC, we recommend that you use exclusive resource groups.
Note
  • Exclusive resource groups for Data Integration guarantee the number of threads that a data synchronization instance can simultaneously run, not the number of data synchronization instances that can be simultaneously run. To guarantee the number of data synchronization instances that can simultaneously run, you can purchase exclusive resources for scheduling.

Performance metrics

You can use instances with different specifications in exclusive resource groups for Data Integration. The maximum number of data integration nodes that an instance can run varies based on the specifications. Before you purchase an exclusive resource group, we recommend that you estimate the number of concurrent data integration nodes and the required resource specifications based on your business needs. This can prevent nodes from waiting for resources due to the upper limit on the number of concurrent nodes.

For more information about the supported specifications and maximum number of nodes, see Performance metrics of exclusive resource groups for Data Integration.

Billing method

Exclusive resource groups for Data Integration are billed in subscription mode. You can choose instances with appropriate specifications as needed. For more information, see Performance metrics and billing standards of exclusive resource groups for Data Integration.

Network connectivity

  • Network connectivity
    • The data store is deployed on the Internet. In this case, the exclusive resource group can directly access the data store.
    • The data store is deployed in a VPC.
      • Assume that the data store and the exclusive resource group reside in the same region. We recommend that you bind the exclusive resource group to the VPC where the data store resides and then to a vSwitch that resides in the VPC. Then, the system automatically adds a route for the exclusive resource group. This way, the exclusive resource group can access the data store.
      • Assume that the data store and the exclusive resource group reside not in the same region. You must connect the VPC where the exclusive resource group resides to the VPC where the data store resides by using Express Connect circuits or VPN gateways.
    • The data store is deployed in a data center. In this case, you can connect the data center to the VPC where the exclusive resource group resides by using Express Connect circuits or VPN gateways.
    • The data store is deployed on the classic network. Exclusive resource groups are deployed in VPCs of Alibaba Cloud. If your data store is deployed on the classic network of Alibaba Cloud, the exclusive resource groups cannot access the data store. In this case, we recommend that you bind the data store to a VPC.
  • Whitelist configuration. Assume that a whitelist is configured for the data store to allow only specified IP addresses to access the data store. You must add the elastic IP address (EIP) of the resource group and the Elastic Network Interface (ENI) IP address of the VPC to the whitelist. For more information, see Obtain the IP address and CIDR block of an exclusive resource group for Data Integration.

Other instructions

  • Scale-out
    You can scale out the exclusive resources for Data Integration in each order based on your business needs. You need to pay only for the added resources from the time when you scale out the resources to the time when the original order expires.
    Note
    • Exclusive resources for Data Integration in a single order can be used in only one exclusive resource group for Data Integration. The resources cannot be split among multiple exclusive resource groups for Data Integration. After you pay for the order, you can increase the number of resources in the order to scale out the resources.
    • Scale-out increases the number of resources but does not upgrade their CPU and memory configurations.
    • Scale-out allows you to add only resources of the same specifications as the purchased resources in the current order.
    • After you scale out the resources in an order, the new configuration takes effect within 20 minutes after you pay for the order.
  • Renewal

    You can renew the exclusive resources for Data Integration in an order before the order expires or within 30 days after the order expires. If you do not renew your subscription within 15 days after expiration, the services for resources in the order are suspended immediately after this 15-day period.

  • Expiration
    • Service suspension

      By default, the system sends expiration notifications to the mobile number and email address that are bound to your Alibaba Cloud account eight days, 12 days, and 14 days before your order for the exclusive resource group for Data Integration expires. If you do not renew your subscription within 15 days after expiration, the services for resources in the order are suspended immediately after this 15-day period.

    • Resource release

      After the exclusive resource group for Data Integration expires, it is retained for 15 days. If you do not renew your subscription within 15 days, the exclusive resource group for Data Integration is released after this 15-day period.

      The system sends release notifications to the mobile number and email address that are bound to your Alibaba Cloud account one day before the exclusive resource group for Data Integration is released.
