Use legacy resource groups

Key concepts

DataWorks legacy resource groups include exclusive resource groups and shared resource groups, categorized by scenario: scheduling, Data Integration, and Data Service. Scheduling resource groups handle task scheduling and execution. Data Integration resource groups handle data transmission. Data Service resource groups process API calls.

Resource group type	Billing method	Resource group description	Scheduling resource group	Data Integration resource group	Data Service resource group
Exclusive resource group	Subscription	Platform-hosted resource groups with exclusive access after purchase. Can be associated with a workspace for resource isolation between workspaces. Supports flexible scaling, upgrades, and specification changes.	Billing of exclusive resource groups for scheduling	Billing of exclusive resource groups for Data Integration	Exclusive resource groups for DataService Studio Note Exclusive resource groups for Data Service are available only in the China (Shanghai) region.
Shared resource group	Pay-as-you-go	Automatically provided when you activate DataWorks, including shared resource groups for Data Service and shared resource groups for scheduling. These are shared within a tenant, so tasks may need to wait for resources during peak periods.	Use a shared resource group	-	Use a shared resource group

Comparison between shared and exclusive resource groups

Scheduling resource groups

Category	Shared resource group for scheduling	Exclusive resource group for scheduling
Machine ownership	Maintained by DataWorks. Shared across all tenants.	Maintained by DataWorks. Dedicated compute resources for each tenant.
Network connectivity	Network connectivity is not guaranteed. Examples: The data source is on the public network but uses an allowlist that restricts access from unknown IP addresses. The data source is in an Alibaba Cloud VPC environment.	Supports network configurations for complex network environments. For more information, see Billing of exclusive resource groups for scheduling.
Task timeliness	Shared among DataWorks users. Timeliness cannot be guaranteed.	Dedicated to the tenant. You can control concurrency and ensure timely task execution.
Applicable scenarios	Shared resources may cause task blocking under heavy load. Suitable only for low-concurrency, low-frequency scenarios.	Tenants can control concurrency and perform scaling or specification changes. Suitable for large task volumes with high timeliness requirements.
Billing method	Pay-as-you-go. For more information, see Scheduling instance fees.	Subscription. For more information, see Billing of exclusive resource groups for scheduling (subscription).
Other comparisons	Timeliness: Shared scheduling resource groups are shared by all DataWorks users. For tasks with timeliness requirements, use exclusive resource groups for scheduling. Non-public network access: Shared resource groups cannot access non-public environments with allowlist restrictions. For such requirements, use exclusive resource groups for scheduling. Task volume: For a large number of daily scheduled tasks, use subscription-based exclusive resource groups for scheduling.

Data Integration resource groups

Category	Exclusive resource group for Data Integration
Machine ownership	Maintained by DataWorks. Dedicated compute resources for each tenant.
Network	Public network access is supported. With network configuration, you can access databases in any network environment.
Supported data sources	All data sources.
Task execution timeliness	Dedicated to the tenant. You can control concurrency and ensure timely task execution.
Applicable scenarios	Large-volume, important production tasks.
Billing	Subscription. For more information, see Billing of exclusive resource groups for Data Integration (subscription).
Selection guide	Timeliness: When Data Integration tasks run with high concurrency and cannot be staggered, use exclusive resource groups for Data Integration to ensure fast, stable data transmission. Private network access: Exclusive resource groups for Data Integration support public network synchronization. Some databases cannot be synchronized directly over the public network due to inherent characteristics. For more information, see the documentation for each data source and plug-in: Supported data source types, Reader plug-ins, and Writer plug-ins. Complex network environments: To access databases in complex networks, use subscription-based exclusive resource groups for Data Integration. For network solutions, see Network connectivity solutions. Real-time synchronization: Requires exclusive resource groups for Data Integration. Data source compatibility: Some data sources support only exclusive resource groups for Data Integration. For more information, see Data source types that support real-time synchronization.

Data Service resource groups

Shared Data Service resource groups are shared among tenants. For high-concurrency, high-frequency API calls that require prompt responses, use exclusive resource groups for Data Service to ensure availability and stability. For billing details, see Billing of exclusive resource groups for DataService Studio (subscription) and Data Service.

Notes

When you activate DataWorks, pay-as-you-go shared resource groups are provided by default. You can also purchase subscription-based exclusive resource groups, or upgrade to DataWorks Standard Edition, Professional Edition, or Enterprise Edition to use your IDC machines as resource groups.
Different legacy resource group types are used at different task execution stages. For an overview of batch task dispatching and resource group usage, see Task dispatching mechanism for legacy resource groups.
At the same execution stage, tasks can use different resource group types. For example, batch scheduling supports both subscription-based exclusive and pay-as-you-go shared resource groups. For more information, see Comparison between shared and exclusive resource groups.
Both shared and exclusive resource groups are integrated with Security Center Free Edition by default, which provides basic security hardening such as abnormal login detection, DDoS attack detection, and vulnerability scanning. For more information, see Security Center Free Edition.

Task dispatching mechanism for legacy resource groups

Scheduling resource groups dispatch batch tasks to engines or servers for execution. For example, scheduling resource groups dispatch tasks to MaxCompute for execution. Batch Data Integration tasks are dispatched through scheduling resource groups to Data Integration execution resources. Shared resource group for Data Integration
