When you use DataWorks to synchronize data, you can use only exclusive resource groups for data integration to run real-time data synchronization nodes. This topic describes the resources and configurations required to run real-time data synchronization nodes.
- Resource planning and preparation
Before you use a data synchronization node to synchronize data, you must purchase an exclusive resource group for data integration and add the resource group to DataWorks for subsequent use.
For more information about exclusive resource groups for Data Integration, see Overview of Data Integration.
- Network connections
An exclusive resource group for Data Integration is essentially a group of Elastic Compute Service (ECS) instances. After you purchase and create such an exclusive resource group, it is isolated from other services. You must associate the resource group with a virtual private cloud (VPC) to ensure network connectivity between the resource group and data sources during subsequent data synchronization.
