What-If for Current Workloads

Use What-If for Current Workloads to help you understand how cost changes to specific services can affect the cost of workloads (groups of services generally delivered together). To do this, build scenarios that calculate prospective changes to cost and usage. If the estimated changes suit your needs, you can save a model as a new rate plan.

Before you begin

You must have services available in Cloud Cruiser. You must also have an active rate plan, with charges recorded for the usage of services.

Creating a What-If scenario for current workloads

To create a What-If scenario for current workloads

  1. Select What-If > Current Workloads.
  2. In the Scenarios list, right-click and select Create new scenario.
    The Create new rate scenario dialog box appears.
  3. Provide information that defines the scenario and populates the Baseline model:
    1. In the Properties section, specify the following information, and then click Next:
      Field Description
      Name A name for this scenario. The name appears in the Scenarios list when you save the scenario.
      Type The type of scenario you want to run:
      • Single Baseline: Includes a fixed Baseline model representing actual usage and charges for a chosen period. You can then compare the results of the other models in the scenario to the Baseline model. All models share the same set of services and customers. This type of scenario is good for modeling several possible future states, including changes to pricing and demand.
      • Free Form: Though it includes a Baseline model, each model in the scenario can use a different set of customers and services. This type of scenario offers the most flexibility.
      Rate Plan The rate plan you want to use for cost calculations.
      Baseline Period The period of time containing collected usage and pricing data to be used in the baseline model and your editable models. This period is the same for all models, whether you include them in a reset.
      Description A description of this scenario. For example, you might describe the type of changes you are exploring.


    2. In the Services section, select the services you want to include in the scenario, and then click Next. To select all available services, select the check box at the top of the list.
    3. In the Customers section, select the customers you want to include in the scenario.
    4. Click Finish.
      The new scenario is created, with the Baseline model displayed by default. The scenario also includes a new model (the Model tab next to the Baseline tab), ready for your rate changes.
  4. Click the Model tab, and then make changes to the modeled rates, as you would when creating a new rate plan.
    For detailed information about the fields, see Managing rate plans.

    As you make changes to the model, Cloud Cruiser updates the Total Charges line above the table to show the differences between your model and the Baseline model.

    • Each service must have either a Unit Price or a Fixed Price.
    • If you want to adjust expected usage for one or more services, do so in the Usage column.
    • To give the new model a name, right-click the Model tab, select Rename model, and then enter a new name.
  5. If you want to make changes to every service in the model:
    1. Click Bulk Edit.
      The Bulk Edit dialog box appears.
    2. In the first field, select whether you want to Increase, Decrease, or Set a value for services.
      When you increase or decrease a value, it is adjusted as a percentage of its current value. When you set a value, independent of its relation to the original number.
    3. In the second field, select the value you want to adjust: Unit Price, Fixed Price, or Usage.
    4. In the last field, enter the value.
    5. Click OK.
  6. If you want to edit the services used in the scenario, click Edit Services, and then select the services you want to use.
  7. If you want to edit the customers used in the scenario, click Edit Customers, and then select the customers you want to use.
  8. If you want to change the time period of usage used in the scenario, click Reset Usage, and then select a new Baseline Period, and the models to be updated.
  9. To see a sample invoice for usage in the new model, click Preview Invoice.
  10. If you want to export the sample invoice, click Export, and then select a file format.
  11. Click Save to save the changes to your scenario.

Promoting a model as a new rate plan

After seeing the impact of your changes, you might want to put those changes into production. Use the Promote Model function use your model as a new rate plan, or as a new range of an existing rate plan.

To create a new rate plan based on a scenario

  1. Open the model you want to promote.
  2. Click Promote Model.
    The Promote Rate Model dialog box appears.
  3. In the Rate Plan field, take one of the following actions:
    • To create a new rate plan, enter a unique name.
    • To modify or overwrite an existing rate plan, select that rate plan from the drop-down menu.
  4. In the Start Date field, select the first date of the rate plan.
    If you are modifying an existing rate plan, a new range is created in that plan.
  5. Click OK.
    Your rate plan is promoted, and Cloud Cruiser opens the new plan on the Rate Plans page.
