      Note

      If you want to use the resource group to access a data source, such as an Alibaba Cloud data source or a self-managed data source hosted on an ECS instance, you can select a network connectivity solution and configure network settings based on whether the resource group and data source belong to the same Alibaba Cloud account.

      Parameter

      Description (same region and Alibaba Cloud account)

      Description (different regions or Alibaba Cloud accounts)

      VPC

      If your data source and the exclusive resource group belong to the same Alibaba Cloud account, we recommend that you select the VPC in which your data source resides.

      If your data source and the exclusive resource group belong to different Alibaba Cloud accounts, configure this parameter based on the description for the scenario where your data source and the exclusive resource group reside in different regions.

      If your data source and the exclusive resource group belong to different Alibaba Cloud accounts or reside in different regions, you must select a VPC that connects to the data source. For example, if your data source does not reside in a VPC, you can click Create VPC to create a VPC for the exclusive resource group. After the VPC is created, you can select it from the VPC drop-down list. You can also select a VPC that connects to your data source.

      Note

      If your data source and the exclusive resource group reside in different regions or belong to different Alibaba Cloud accounts, you must use VPN Gateway or Express Connect to establish a connection between the VPC with which the exclusive resource group is associated and the VPC in which the data source resides and add a route that points to the IP address of the data source for the exclusive resource group. For more information, see Establish a network connection between a resource group and a data source.

      Zone

      Select the zone in which your data source resides.

      Select a zone from which a network connection to your data source is established.

      vSwitch

      If you set the VPC parameter to the VPC in which your data source resides, we recommend that you select the vSwitch with which the data source is associated.

      Note

      After you associate the exclusive resource group with the VPC in which the data source resides and a vSwitch that resides in the VPC, a route that points to the CIDR block of the VPC is automatically added. This ensures that the exclusive resource group can access the data sources in this VPC.

      Select the vSwitch to which the data source is connected. If no vSwitch is available, you can click Create VSwitch to create a vSwitch for the exclusive resource group. After a vSwitch is created, select the vSwitch.

      Security Groups

      Security groups allow or deny access to the exclusive resource group over the Internet or an internal network. You can select an existing security group based on your business requirements, or click Create Security Group to create a security group for the resources in the exclusive resource group. For information about how to create a security group, see Add a security group rule.

    2. Click OK.

    Note

    If your data source and the exclusive resource group reside in different regions or belong to different Alibaba Cloud accounts, you must add a route that points to the IP address of your data source after you associate the exclusive resource group with a VPC.

  4. Add host configurations. This operation is optional.

    You may fail to access your data source by using IP addresses. For example, you can access your data source only by using hostnames. In this case, you must perform the following steps to add host configurations. Otherwise, the connectivity test fails when you add the data source by using its hostnames.

    1. Click the Hostname-to-IP Mapping tab. On this tab, click Add. In the Create Hostname-to-IP Mapping dialog box, configure the parameters. The following table describes the parameters.

      Parameter

      Description

      IP Address

      The actual IP address of the data source.

      Hostname

      The hostname that is used to access the data source. If you want to specify multiple hostnames, place each hostname on a separate line.

    2. If the data source has multiple IP addresses, click Add to add more host configurations.

      Note
      • The IP address or hostnames that are added in a host configuration must be different from the IP addresses or hostnames in existing host configurations.

      • You can map one IP address to multiple hostnames in a host configuration. However, one hostname can point to only one IP address.

Configure the IP address whitelist of a data source

Even if your exclusive resource group for Data Integration and your data source reside in the same zone, same VPC, and same vSwitch, the access from the resource group to the data source may still fail due to restrictions of the IP address whitelist of the data source. In this case, you must configure the IP address whitelist of your data source based on the following instructions:

  • If you want to establish a network connection between the exclusive resource group and your data source over an internal network, you must add the CIDR block of the vSwitch with which the resource group is associated to the IP address whitelist of your data source.

    To view the CIDR block of the vSwitch with which the resource group is associated, perform the following operations: Log on to the DataWorks console and click Resource Groups in the left-side navigation pane. On the Exclusive Resource Groups tab, find the exclusive resource group and click Network Settings in the Actions column. On the VPC Binding tab, you can view the CIDR block in the VSwitch CIDR Block column.独享绑定的交换机网段
