• Without resource groups, users are automatically assigned to the best available cluster. With resource groups, users are assigned to a specific cluster and remain that way unless you manually reassign them.

  • Understand the risk of assigning a user to a resource group. If a cluster within a resource group fails, users are mapped to another cluster within that resource group. But if no other cluster exists, users are out-of-service until the cluster is brought back up.

Class of Service

You may have a selection of servers that have a higher resiliency than the others in your deployment. In that case, you can use resource groups to assign users to the servers in those clusters. You can name the resource groups based on department, location, or another relevant identifier. Resource groups ensure that assigned users are only hosted on those specified clusters.

Regulation or Data Sovereignty

If you have distributed Expressways, you can assign users to specific ones if they shouldn't be queried in certain locations. For example, a user in Germany can be assigned to a resource group cluster in Germany, which ensures that the user never lands on a cluster in a different location.

If there are no specific requirements for user assignment, let the automatic user assignment happen and do not use resource groups. With automatic assignment, users can automatically be sent to clusters that have capacity if there is a failure on a specific cluster.

Resource groups organize Expressway hybrid clusters around a specific purpose and isolate the clusters from the others that host hybrid services. To build a resource group, assign resources (Expressway clusters) to the resource group and give it a name that identifies its purpose (class of service, geography, or data sovereignty).

1

From the customer view in https://admin.webex.com, go to Services, and then choose On-Premises Resources from the cluster list card.

2

Click Expressway to filter on the resources for Expressway-based hybrid services.

3

Click , and then choose Create new Resource Group.

4

Follow the on-screen directions to enter the name (the resource group purpose) and then click Done.

5

Follow the link to assign clusters to the resource group. Read any caution notes to understand potential service impacts, and then click Done.

You can update users individually or in bulk so that they're assigned to the resource group.

Before you begin

By default, users are automatically assigned to the best available cluster. You do not need to create resource groups to match users with the appropriate cluster.

From the customer view in https://admin.webex.com, go to Users, and then choose one:

  • For individual users, click the individual username to open the overview page, choose the Call or Calendar Service, and then in the Resource Group drop down, choose the resource group to associate that user to for the specific hybrid service.
  • For multiple users, follow the directions in Modify Users in Cisco Webex Control Hub with the CSV Template to assign multiple users to resource groups. The resource groups are listed in the CSV file. Under a Call or Calendar resource group column, enter TRUE to assign a user to the resource group.

For your reference, you may need a filtered list of users that you assigned to resource group users. You can obtain this list as a .csv file from Cisco Webex Control Hub.

1

From the customer view in https://admin.webex.com, go to Services, and then choose a Hybrid Service card.

2

Click User Status Report and then check the activated users check box.

3

Click Export to CSV.

4

Open the csv file.

The resource group column shows which clusters that users are assigned to.

From one place, you can make changes to your resource groups after you create them.

Before you begin

Some changes that you make may affect running services.

1

From https://admin.webex.com, go to Services, and then click All Resources from the On-Premises Resources card.

2

Click Expressway to filter on the resources for Expressway-based hybrid services.

3

Scroll to the resource group card, and then click settings .

4

From the settings page, do these steps as needed:

  • Add more clusters to the resource group.
  • Enable users for the resource group, individually or in bulk.
  • Rename the resource group.
  • Remove the resource group, if it contains no clusters.
