Creating a Cost Allocation Cost Model

Cost > Cost Management > Cost Allocation 360°


Before you begin to use cost allocation reports, you need to create the policies you want to use in Cost reports.


To create a policy:

  1. From Cost Managment, select Cost Allocation 360°.
  2. In Cost Allocation 360°, click Add +. The Add Cost Model window is displayed.
  3. In the Add Cost Model dialog box, give the policy a name and description.
  4. Click OK and begin customizing the cost policy.
  5. In the Accounts tab, select the relevant account(s) to be included in the policy. (You can select AWS and Azure accounts in the same policy.)
  6. In the Categorization tab, select the tag categories you want to include in the policy. These will be the tag categories available in the report.
  7. In the Uncategorized Resources tab, create the relevant allocation rules (policies) for uncategorized resources. 

    For AWS, if you do not have specific requirements, you can begin by creating two generic rules:

     - Create your first rule by selecting all AWS except RDS and then select Proportional to Categorized EC2.
     - Create the second rule for RDS and select Proportional to Categorized RDS.

    For more information on Uncategorized Resources, see Assigning Rules to Uncategorized Resources.

  8.  In AWS Reserved Instances tab, assign reservations to selected accounts or tag categories. (optional – For AWS customers only. AWS have the option of purchasing Reserved Instances for specific tag values such as a department, cost center and linked account).
  9. In Summary, review the new rule details in a single view.
  10. Click Save and Activate. The policy data is processed.

Note: Processing may take some time. Please allow a few hours for it to complete.
