What-If for New Workloads

Use What-If for New Workloads to help you decide which workloads provide the necessary services at the best cost. To do this, build scenarios that compare the estimated costs for different groups of services. For example, you might compare services offered from a single provider to see which is the best value from that provider. You might then compare that workload against a similar workload from a different provider to help you make an informed business decision about the services you purchase.

What-If functionality in Cloud Cruiser requires a special license. If you do not see What-If available in the Cloud Cruiser navigation pane, contact Cloud Cruiser.

Before you begin

You must have services available in Cloud Cruiser, but you do not need to have collected actual usage data for those services. What-If for New Workloads helps you estimate future cost based upon usage that you estimate.

You must also have at least one rate plan in Cloud Cruiser to provide the baseline costs Cloud Cruiser uses to estimate daily, monthly, and yearly costs.

Creating a What-If scenario for new workloads

To create a What-If scenario for new workloads

  1. Select What-If > New Workloads.
  2. In the Scenarios list, right-click and select Create new Scenario.
    The Create new Scenario dialog box appears.
  3. Enter a Name, and (optionally) a Description for the new scenario.
  4. Click OK.
    The new scenario opens, with focus on the first model. Each model represents a group of services you want to compare. For example, you might want to compare a model that includes a group of small VMs with a model that includes a single medium VM.
  5. In the Rate Plan field, select the rate plan you want to use for cost estimations.
  6. In the Effective Dates field, select the date range to use for cost estimations.
    A rate plan might include different rates for different ranges.
  7. Add one or more services to the model:
    1. Click Add New Service.
      A new row appears in the table.
    2. In the Service field, select a service.
      The list of available services is determined by the services you have imported or created manually in Cloud Cruiser. Passthrough services are not listed.
    3. In the Count field, enter the number of this service you want to include in the model.
      For example, you might decide that a model for a small VM configuration should include 3 instances of the Small VM service.
    4. If the service is an allocated service, in the Hours per Day field, enter the number of hours you expect each instance of the service to be used each day. (Cloud Cruiser estimates the cost of metered services only by Count.)
      For example, you might each of the 3 instances of the Small VM service to be used for 12 hours each day.
  8. Add other services to the model as needed.
    For example, you might add a service for storage.
  9. To rename the model, right-click the Model tab, and select Rename Model.
    For example, you might name the first model Small VM.
  10. To add a new model, click the (New) model tab, and then add services just as you did for the first model.
    For example, you might create a second model named Medium VM, which includes the same storage service, but incudes a single medium VM service instead of 3 instances of the Small VM service.
  11. When you have added all of the models you want to compare, click Review.
    The Review page shows a summary of the estimated Daily, Monthly and Yearly costs of all models in the scenario, with the least expensive model at the top, and most expensive model at the bottom. You can return to the Models page at any time to revise existing models or add new models.
  12. Click Save to save the scenario.
