DataWorks:Billing for exclusive resource groups for Data Integration

DataWorks no longer recommends exclusive resource groups for Data Integration

DataWorks no longer recommends exclusive resource groups for Data Integration. Use Serverless resource groups instead. Serverless resource groups cover the core features of legacy resource groups, such as exclusive resource groups for scheduling, exclusive resource groups for Data Integration, exclusive resource groups for DataService Studio, and public resources. A single Serverless resource group lets you perform operations such as data synchronization, task scheduling and execution, and API service calls and management.

Function Introduction

The features of exclusive resource groups for Data Integration are as follows:

• They support data synchronization in complex network environments, such as cross-cloud platforms like Alibaba Finance Cloud and Alibaba Gov Cloud, across different Alibaba Cloud accounts, or with on-premises data centers.

• Data Integration provides fast and stable data movement and synchronization between various disparate data sources. It supports a wide range of synchronization requirements, such as offline to real-time, single table to entire database, and full and incremental data. For more information, see Supported data sources and synchronization solutions.

Limits

• The billing method for exclusive resource groups for Data Integration is subscription. You cannot delete or release resource groups before their subscriptions expire. After a subscription expires, the service is suspended and the resource group is released after a specific period.

• Exclusive resource groups for Data Integration do not support cross-region use. For example, an exclusive resource group for Data Integration in the China (Shanghai) region can be used only by workspaces in the China (Shanghai) region.

• Exclusive resource groups for Data Integration do not support access to Alibaba Cloud classic networks. If your data source is in a classic network, you must migrate the data source to a virtual private cloud (VPC) or enable public network access.

Network connectivity solutions

Exclusive resource groups for Data Integration are essentially a group of Alibaba Cloud ECS instances, similar to other types of exclusive resource groups. When a data integration task runs, you must ensure that the resource group and the data source are connected over the network. You must also ensure that security settings, such as whitelists, do not block the network connection between the resource group and the data source.

After you purchase an exclusive resource group for Data Integration, you must attach it to a VPC. You can then choose a network connectivity solution based on the network environment of your data source. For more information, see Network connectivity solutions.

• Network connectivity solutions

  Data source network environment	Network connectivity solution
  The data source is on the Internet.	Connect the data source directly to the VPC that is attached to the exclusive resource group.
  The data source is in a VPC in the same region as the exclusive resource group.	Attach the exclusive resource group to the same VPC as the data source. When you attach the resource group to a vSwitch in the VPC, the system automatically adds a route that allows the resource group and the data source to connect to each other.
  The data source is in a VPC in a different region from the exclusive resource group.	Use a service such as Express Connect or VPN to connect the VPC of the data source to the VPC of the exclusive resource group. Add a route that points to the destination database IP address to ensure network connectivity.
  The data source is in an on-premises data center.	Use a service such as Express Connect or VPN to connect the on-premises data center to the VPC of the exclusive resource group. Add a route that points to the destination database IP address to ensure network connectivity.
  The data source is in a classic network.	Exclusive resource groups reside in a VPC and cannot connect to data sources in a classic network. You must migrate the data source to a VPC.

• Whitelist configuration

  If the data source uses a whitelist to restrict access, you must add the endpoint of the exclusive resource group to the data source's whitelist to ensure proper access. For more information, see Add a whitelist.
