Elastic Algorithm Service (EAS) provides dedicated resource groups and virtual resource groups. You can use a dedicated resource group to purchase and manage dedicated resources. A virtual resource group lets you deploy services using various resource types, including public resources, dedicated resources, and Lingjun resources.
Dedicated resource groups
Resource types
Dedicated resources are available in two billing methods: Subscription and Pay-as-you-go. The following table compares them.
Type | Billing method | Resource group management | Supported resource type |
Subscription resources | Subscription | You can purchase nodes, renew subscription nodes, delete pay-as-you-go nodes, and delete resource groups. For more information, see Manage nodes in a dedicated resource group. | You can view the supported resource types on the EAS pre-payment for dedicated machine buy page. |
Pay-as-you-go resources | Pay-as-you-go | You can view the supported resource types on the EAS post-payment for dedicated machine buy page. |
Pay-as-you-go resources start billing once purchased regardless of whether they are deployed for services. We recommend that you delete unused pay-as-you-go resources to avoid unnecessary 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 Group tab. On the Resource Group tab, choose Create Resource Group > Create Resource (Subscription) or Create Resource (Pay by Usage). Configure the following parameters.
Parameter
Description
Billing Method
Select Subscription or Pay-as-you-go.
Region and Zone
Select the region and availability zone for the resource group.
Node Type
The supported GPU and CPU specifications. For a detailed list of resources, see EAS pre-payment for dedicated machine or EAS post-payment for dedicated machine.
NoteThe available Node Type vary by region.
System Disk
Each node includes a 200 GB system disk for free. You can increase the storage capacity from 200 GB to 2,000 GB. For information about charges for extra capacity, see Billing of EAS.
NoteAll service instances share the system disk space. If the disk space is insufficient, service instances that consume a large amount of space are evicted. To allow your instances to read from and write to a local disk directory at runtime, see mount storage to the service.
Billing Method
Select Create Resource Group or Existing Resource Group.
If you select Existing Resource Group, you must configure the Resource Group ID parameter.
Resource Group ID
Select the ID of an existing resource group from the list.
Quantity
Enter a value from 1 to 9,999.
Subscription Duration
Valid values: 1 Month, 2 Months, 3 Months, 6 Months, 1 Year, 2 Years, 3 Years, and 5 Years. This parameter applies only to the Subscription billing method.
Auto-renewal
Specifies whether to automatically renew the subscription upon expiration. This parameter applies only to the subscription billing method.
Click Buy Now.
After you complete the payment, the system automatically provisions the resources. On the Resource Group tab, you can view all created resource groups or modify their names.
NoteFor subscription resource groups, if the system fails to create the resource group due to insufficient resources in the selected region, the system automatically issues a full refund.
Manage nodes in a dedicated resource group
Purchase a node |
|
Renew a node (Applicable only to pay-as-you-go instances) | You can extend the subscription duration of a resource group. For example, if you renew a subscription resource group for one month, the subscription duration of the resource group is extended by one month.
|
Delete a node from a dedicated resource group | Pay-as-you-go instance: On the Nodes tab of the details page of the dedicated resource group, find the instance that you want to delete, click Delete in the Actions column. Subscription instance: For more information, see EAS FAQ |
View the resource usage of a node | On the Resource Group tab, click the name of the dedicated resource group. Then, on the Nodes tab, view the usage of CPU, GPU, and Memory of each node. |
Stop scheduling | If an instance is in the Running status, you can click Stop Scheduling in the Actions column to make the instance unschedulable. You can click Restart Scheduling to restore the instance to the running status. Note After you click Stop Scheduling, the services on the node still run normally. After you click Restart Scheduling, the nodes that are available in the resource group are scheduled for service deployment. |
Clear a node | After you click Clear Node, instances on the node will automatically stop and the nodes that are available in the resource group are scheduled for service redeployment. Important After you click Clear Node, the tasks running on the instance are terminated. Proceed with caution. |
icon in the Actions column, and then select Renew. Virtual resource group
An EAS virtual resource group is a logical grouping that combines resource types, such as public resources, resource quotas, and EAS dedicated resources. This feature unifies service deployment and scheduling, letting you run a single service across various underlying resources.
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 Group tab. On the Resource Group tab, click the Virtual Resource Group tab. On the Virtual Resource Group tab, click Create Virtual Resource Group. On the Create Virtual Resource Group page, configure the parameters. If you set the Resource Type parameter to Public Resource Group, you can select instance types that support the bidding feature. You can configure resource types as needed and set a scheduling priority for each resource (1 is the lowest priority, 9 is the highest).
Use a virtual resource group
During service deployment, select EAS Resource Group for Resource Type and select a virtual resource group from the Resource Group drop-down list in the Resource Information section.

You can enable virtual private cloud (VPC) direct connect for services deployed in a dedicated resource group. For more information, see Enable EAS to access the internet and private resources.
You can configure log collection for a resource group. After the configuration is complete, the system collects the logs generated by EAS services that are deployed in the resource group and stores the logs in your Simple Log Service. For more information, see Configure log collection for a resource group.
FAQ
Q: Can I deploy multiple models into a single EAS resource group?
Yes. A single resource group can be used to deploy multiple model services, provided it has sufficient resources.
Q: Is it possible to use EAS dedicated resources for DLC distributed training?
No. Currently, EAS dedicated resources can only be used to deploy EAS services and are not available for use with DLC.
