Elastic Desktop Service:Create and manage computer pool cloud computers

Background

A computer pool automatically creates, assigns, and releases cloud computers based on the billing method and scaling policy that you configure. For more information about how a computer pool works, see Overview of computer pools (formerly desktop groups).

Create a computer pool

1. Log on to the EDS enterprise console.

2. In the left-side navigation pane, choose Resources > Cloud Computer Shares.

3. In the top navigation bar, select a region.

4. On the Shared Cloud Computer page, click the Computer Pool tab, click Create Shared Cloud Computer, and configure the parameters.

   Parameter	Description
   Billing Method	The default billing method for the computer pool. Subscription: You pay upfront for resources at discounted pricing. Pay-as-you-go: You are billed based on the specifications and duration of use, and you can release resources at any time. For more information, see Billing overview.
   Name	The name of the computer pool. Follow the naming conventions shown on the page.
   Select Region	The region where the cloud computers are deployed.
   Office Network	The office network to which the cloud computers belong. Convenience office networks and AD office networks are supported. For more information about office network types, see Office network types.
   Select Users	After you add users to a computer pool, cloud computers are dynamically allocated to them based on connection status. Unlike standard cloud computers, cloud computers in a computer pool are not permanently bound to users. When a user disconnects, the system automatically resets the cloud computer based on the configured reset type, making it available for another user. To add users after the share is created, select Close. To add users during creation, select Open. For a convenience office network, click Authorize User to select existing convenience accounts. You can also click Create User to create new users before adding them. For more information about how to create a convenience account, see Create a convenience account. For an AD office network, click Authorize User to select AD accounts from your AD domain controller. Alternatively, go to the By Uploading tab to bulk upload user account information from a CSV file. Note You can import a maximum of 500 AD accounts at a time from a CSV file. Bulk upload AD account information from a CSV file In the Select Users panel, click the By Uploading tab. Prepare a CSV file in one of the following ways: Click Download CSV Template, open the downloaded template, enter the AD account information in the required format, and then save the file. Use spreadsheet software to enter the AD account information in the required format and save the file as a CSV file. Click Select File, choose the CSV file that contains the AD account information, and click OK. The system automatically uploads the CSV file and verifies the AD account information against the accounts in your AD domain controller. You can click View Match Details to check the results. You can assign cloud computers only to users in the Matched User list. For users in the Mismatched User list, you can correct the information and click Resubmit.
   Data Roaming	Enable this feature to ensure that data in a user's C:\Users\<username> directory persists across sessions, providing a consistent user experience. For a detailed description and configuration steps, see Configure user data roaming (UPM).
   Security Policy	The policy for the computer pool. It controls usage restrictions and experience settings for the cloud computers. You can select an existing security policy or create a new one as prompted on the page. For more information, see Create and manage cloud computer policies.
   Templates	The cloud computer template that defines the specifications and image for computer pool cloud computers. You can select an existing template or create a new one as prompted. For more information, see Create and manage custom templates. Note Cloud computer templates that use custom Linux images are not supported. To enable user data roaming, make sure that the image version in the selected template is V1.9.0 or later.
   Tag	Tags help you categorize and manage cloud computers.
   If you select Subscription as the billing method, you must configure the following parameters:
   Quantity	The initial number of cloud computers to create.
   Duration	Select a subscription duration for the computer pool. You can also enable auto-renewal based on your business needs.
   Allow Automatic Creation	If you enable Allow Automatic Creation, the system automatically creates and assigns a new pay-as-you-go cloud computer from the selected template when all cloud computers in the share are occupied and a new user attempts to connect. The new cloud computer is released 10 minutes after the user disconnects.
   Max. Auto-created Cloud Computers	If you enable Allow Automatic Creation, you must set the maximum number of cloud computers that the system can automatically create. This helps control your overall costs.
   If you select Pay-as-you-go as the billing method, you must configure the following parameters:
   Min. Cloud Computers	The initial number of cloud computers created for the computer pool. These cloud computers are always reserved. When you release the computer pool, these initial cloud computers are released at the same time.
   Status of Min. Cloud Computers	By default, all cloud computers in a computer pool are in the Running state. In the Running state, you are charged for both computing and storage resources. To optimize costs, you can set the status to Stopped. In the Stopped state, you are charged only for storage resources, not for computing resources.
   Max. Cloud Computers	Set the maximum number of cloud computers for the computer pool based on your needs. The system automatically creates cloud computers based on user connection status but does not exceed this limit. The maximum value is 500.
   Reserved Idle Cloud Computers	The default value is 0. If you set a value greater than 0, the system pre-creates that number of cloud computers and keeps them running and idle, ready for immediate connection. This reduces user waiting time. Note If you do not reserve available cloud computers, the system must first create and start a cloud computer before assigning it to a connecting user, which increases the waiting time. We recommend that you reserve a certain number of cloud computers to ensure a good user experience.

5. Review the parameter settings and costs, and then click Confirm Order.

6. Confirm the information again, select the Product Terms of Service checkbox next to Service Agreement, and then click Create Order.

   • If you selected the pay-as-you-go billing method, the creation process is now complete.

   • If you selected the subscription billing method, click Subscribe on the payment page and follow the prompts to complete the payment.

Configure user data roaming (UPM)

In a computer pool, cloud computers are not permanently bound to users, and data may be automatically reset based on the administrator's policy. As a result, users' personalized settings and data may not persist by default.

User data roaming uses User Profile Management (UPM) to save data from the C:\Users\<username> directory to the C:\Users directory on the File Storage NAS volume mounted to the office network of the computer pool. This allows user data in C:\Users\<username> to persist across sessions while remaining visible only to the user.

To enable and configure user data roaming:

1. Perform one of the following operations based on your scenario:

   • To enable this feature for a new computer pool, select Open in the Data Roaming section on the page for creating a computer pool.

   • To enable this feature for an existing computer pool, go to the Computer Pool tab of the Computer Pools page, click the computer pool ID of the target computer pool, and on the Basic Information tab, turn on the Data Roaming switch in the lower-right corner of the Shared Cloud Computer Basic Information section.

2. Select an existing NAS file system, or click Create NAS File System and follow the prompts to create a new one.

   Note

   • Creating a NAS file system for a computer pool to enable user data roaming requires Key Management Service (KMS). If you have not activated this service, follow the prompts to activate it in the Create NAS File System panel.

   • Before you use the user data roaming feature, you must initialize the NAS file system. This process takes some time, during which you cannot change the user data roaming settings. The feature becomes active only after initialization is complete.

   • For more information about File Storage NAS, see General-purpose NAS.

3. (Optional) By default, all data in the user directory is roamed. To exercise fine-grained control over the roaming scope, you can configure a UPM blacklist and whitelist policy.

   1. Perform one of the following operations based on your scenario:

      • If you are on the page for creating a computer pool, click UPM Blacklist and Whitelist.

      • If you are on the details page of a computer pool, wait for the NAS file system to be mounted, and then click View/Configure Blacklist and Whitelist.

   2. In the UPM Blacklist and Whitelist panel, click Add to Blacklist and add a level-1 blacklist in the dialog box.

      A level-1 blacklist contains folders or files that you want to exclude from the roaming scope.

   3. (Optional) In the Actions column of the target level-1 blacklist directory, click Add Level-2 Whitelist.

      A level-2 whitelist contains folders or files that you want to keep within the roaming scope. After the policy is configured, only the items in the level-2 whitelist (which is under a level-1 blacklist directory) are roamed. All other data is excluded.

Delete or release a computer pool
