Platform For AI:Create a resource group and purchase general computing resources

Account and permission requirements

• Alibaba Cloud account (Recommended): You can use your Alibaba Cloud account to perform all operations without granting additional permissions.

• RAM user: An Alibaba Cloud account holder must grant the RAM user permissions to manage the resource pool or the AliyunPAIFullAccess permission.

  Important

  The AliyunPAIFullAccess policy grants full permissions to manage and operate all PAI resources and features. Exercise caution when you grant this permission. We recommend using your Alibaba Cloud account for these operations.

Create a dedicated resource group

1. Log on to the PAI console and go to the AI Computing Resources > Resource Pool page.

2. On the General Computing Resources tab, click Create Resource Group.

3. In the Create Resource Group dialog box, configure the following key parameters, and then click OK.

   Parameter	Description
   Type	Select Dedicated Resource Group.
   Edition	1.0: Resources can be used only in DSW and DLC modules. 2.0: Resources can be used across DSW, DLC, and EAS modules.
   Availability Zone	Restricts computing resource purchases for this group to the selected availability zone.
   VPC	Optional. Select an existing VPC, vSwitch, and security group from the drop-down lists. Important When you plan the CIDR block for the vSwitch, do not use the system-reserved CIDR blocks: 10.224.0.0/16 and 10.240.0.0/12.
   Security Group
   vSwitch
   Internet Gateway	After you select a VPC, choose one of the following options if you need internet access: Public Gateway: Uses shared public bandwidth to access the internet. Download speeds may be slow under high concurrency. Private Gateway (recommended) (Recommended): Uses dedicated bandwidth that you can configure based on your needs. To use this method, you must create an internet NAT gateway for the VPC, associate an EIP, and configure an SNAT entry. For more information, see Improve internet access speed by using a private gateway.

Purchase general computing resources

Follow these steps to purchase general computing resources for your dedicated resource group. For billing details, see Billing of AI computing resources.

1. On the General Computing Resources tab, find your resource group in the list and click Create Order in the Manage column.

2. On the purchase page, the Resource Group ID, Region and Availability Zone, and Resource Type are automatically selected. Configure parameters such as Node Specification, Cloud Disk Level, Cloud Disk Capacity, Amount, and Duration based on your business needs. After you configure the parameters, click Buy Now.

   You can purchase the following two types of resources:

   • Computing node: Required. Select a node specification to define the resource configuration for your computing nodes.

   • Cloud disk (data disk): Optional. Select a suitable cloud disk performance level and capacity based on your needs.

     Note

     The purchased cloud disk serves as a data disk. It is available in four performance levels: PL0, PL1, PL2, and PL3. To learn how to select a suitable cloud disk level, see ESSD. The billing method for cloud disks is subscription. For more information, see Billing of AI computing resources.

   

   The following list describes possible issues and their solutions:

   • The order does not contain information for the current resource group.

     • Cause: The region was switched, causing a mismatch between the resource group ID and the region.

     • Solution: Switch back to the resource group's default region.

   • The specified instance type is out of stock in zone.

     • Cause: The selected specification is out of stock in the current region or availability zone. This might also be related to the availability zone of the VPC selected for the resource group.

     • Solution: Select a different node specification. Alternatively, create a new resource group without a VPC configuration and try again.

   • The current kind of instance is temporarily not supported.Please choose another kind of ecs to purchase.

     • Cause: The selected specification is not supported for purchase in the current region.

     • Solution: Select a different node specification.

3. After you complete the payment, the order list page displays the purchased computing nodes and cloud disks.

   

   The system automatically splits the order based on the computing nodes you purchased. This allows you to manage orders for each node, such as renewing or unsubscribing.
