Create and manage dedicated and virtual resource groups - Platform For AI

Create and manage resource groups with dedicated machines (subscription or pay-as-you-go) or virtual groups that unify multiple resource types.

Dedicated resource groups

Resource types

Dedicated resources support subscription-based and pay-as-you-go billing.

Type	Billing method	Management	Supported resources
Subscription resources	Subscription	Purchase machines, renew subscriptions, delete pay-as-you-go machines, and delete resource groups. For more information, see Manage machines in dedicated resource groups.	For supported resource types, see EAS dedicated machine subscription.
Pay-as-you-go resources	Pay-as-you-go		For more information, see EAS dedicated machine pay-as-you-go.

Important

Billing starts immediately after purchase, even if no services are deployed. Delete unused pay-as-you-go machines promptly to reduce costs.

Create a dedicated resource group

Log on to the PAI console. Select a region on the top of the page. Then, select the desired workspace and click Elastic Algorithm Service (EAS).

On the Elastic Algorithm Service (EAS) page, click the Resource Groups tab. On the Dedicated Resource Groups tab, select New Resource Group > New Subscription Resource Group or New Pay-as-you-go Resource Group. Configure parameters.

Parameter	Description
Billing Method	Select Subscription or Pay-as-you-go.
Region and Zone	Select the region and zone for the resource group.
Machine Specification	GPU and CPU specifications are supported. For the complete list, see EAS dedicated machine subscription or EAS dedicated machine pay-as-you-go. Note Supported specifications vary by region.
System Disk	Each machine includes a free 200 GB system disk. Expand storage from 200 GB to 2,000 GB. For charges on extra capacity, see EAS billing. Note All service instances share system disk storage. If the system disk runs out of space, instances consuming large amounts of storage are evicted. For instances that read from or write to local disk during runtime, see Mount storage.
Purchase Method	Select New Resource Group or Existing Resource Group. If selecting Existing Resource Group, configure Resource Group ID.
Resource Group ID	Select an existing resource group ID from the list.
Quantity	Specify the number of machines. Valid values: 1 to 9999.
Duration	Select subscription duration: 1 month, 2 months, 3 months, 6 months, or 1 year (subscription resources only).
Auto-renewal upon expiration	Automatically renew resources upon expiration (subscription resources only).

Click Buy Now.

After payment succeeds, the system allocates resources automatically. View created resource groups or modify names on the Resource Groups tab.

Note
(Subscription resources only) If resource group creation fails due to insufficient resources or other reasons, the system creates a refund order automatically. The payment is returned to your account.

Manage machines in dedicated resource groups

Purchase machines	On the Resource Groups tab, select the target resource group. Click Purchase Machine, then select and purchase a subscription or pay-as-you-go machine. For parameter descriptions, see Create a dedicated resource group.
Renew instances (subscription instances only)	Extend the usage duration of a machine. For example, renewing a machine for one month extends its usage period by one month. On the details page of the dedicated resource group, go to the Machine List tab. In the Operations column of the subscription machine, click and select Renew. On the Renewal page, configure Duration and click Buy Now.
Delete machines from dedicated resource groups	Pay-as-you-go machines: On the dedicated resource group details page, click Delete in the Operations column for the target instance. Subscription machines: For more information, see EAS FAQ.
View machine resource usage in resource groups	On the Resource Groups tab, click the target resource group name. On the Machine List tab, view CPU, GPU, and memory usage and total capacity.
Stop scheduling	When a machine instance is Running, click Stop Scheduling in the Operations column to prevent new workloads from being assigned to it. To resume scheduling, click Restart Scheduling. Note After you stop scheduling, services already running on the machine continue. If a service is restarted, it deploys on other available machines in the resource group.
Drain nodes	Click Drain Node to stop service instances on the machine. The instances are redeployed on other available machines in the resource group. Important Draining a node aborts tasks running on the machine. Use this operation with caution.

Virtual resource groups

A virtual resource group combines different resource types, such as public resources, resource quotas, and EAS dedicated resources. This structure enables unified deployment and scheduling across multiple resource types.

Create a virtual resource group

Log on to the PAI console. Select a region on the top of the page. Then, select the desired workspace and click Elastic Algorithm Service (EAS).
On the Elastic Algorithm Service (EAS) page, click the Resource Groups tab. On the Virtual Resource Groups tab, click New Virtual Resource Group. Select Spot Instance for the public resource group. Configure multiple resource types and set scheduling priorities (1 = lowest, 9 = highest).

Use a virtual resource group

When deploying a service, in the Resource Deployment section, set Resource Type to EAS Resource Group. From the Resource Group list, select Virtual Resource Group.

Reference

For model service deployment parameters, see Custom deployment.
Configure VPC direct connections for services deployed in dedicated resource groups. See Access public or private resources from EAS.
Configure Simple Log Service for resource groups to collect EAS service logs in your own SLS Logstore. See Configure Simple Log Service for a resource group.

FAQ

Can I deploy multiple models in one resource group?

Yes. Deploy multiple model services in a single resource group if sufficient resources are available.
Can surplus EAS inference resources be used for DLC distributed training?

No. EAS dedicated resources can only deploy services and cannot be used in DLC.
