Defining and managing on-premises costs

Use the On-premises Costs Definition tab in the Settings page to define the monthly costs of instances (VMs or standalone systems) in your on-premises environment. This tab contains the default cost rates of factors that are considered to compute the cost of an on-premises instance. These default cost rates are estimated by using the Cost Estimator input values. You can provide details of your environment to estimate your monthly cost rates.

To define and manage the cost of an on-premises instance

Ensure that you have the required permissions to edit the Settings page. For more information, see Authorizing-users-to-access-TrueSight-Cloud-Cost-Control.

Log on to the TrueSight console.
Expand the left navigation pane and select Cloud Cost Control.
The Cloud Cost Control page is displayed.
Click Settings > Settings.
The Settings page is displayed.
Click the On-premises Costs Definition tab.

Click the Settings action menu and select Edit.
The Settings page is refreshed and the fields in the Infrastructure Costs per Month section are displayed in the edit mode.

Factor	Description
Hardware	Monthly cost of the system resources: Physical CPU Virtual CPU Memory Storage
Software	Monthly cost per server for various computing platforms, for example, virtualization platforms and operating systems.

These infrastructure cost values are calculated using the values provided in the Cost Estimator Inputs section. If required, you can override the calculated values by directly modifying the unit costs in the Infrastructure Costs per Month panel. The values are re-calculated when you modify any of the values in the Cost Estimator Inputs section and click Estimate costs.

Click Save.
The Settings page is saved with the changes that you made. These settings are applied from the day you make the changes. If you want to apply the changes to the past data, you can trigger a manual refresh of the data. For more information, see Manually-recovering-historical-costs.

To estimate your on-premises costs

Use the Cost Estimator Inputs section to estimate the monthly cost rates of your physical and virtual resources. This section contains the on-premises environment characteristics such as a number of hosts, number of VMs, and operating systems, which are considered to estimate the default cost rates.

The Measured from imported data pane in the Physical Servers and Virtualized Servers panels displays the values calculated based on the imported data in your environment. By default, the cost values in the Physical and Virtualized Servers panels are calculated and displayed based on this measured data. You can choose to override the measured data and modify the values as per your requirement to re-estimate the costs.

The infrastructure cost values are calculated when you modify any of the values in this section and click Estimate costs.

Other Costs

Field	Description
Network
Rack network switch [$]	Specify the cost of the rack network switch that servers are connected to.
Core network hardware [$]	Specify the cost of the core network hardware that you are using in your environment.
Monthly WAN bandwidth rate per Mbps	Specify the cost you are paying for the monthly wan bandwidth.
Monthly WAN bandwidth	Enter the monthly wan bandwidth rate that you are using in your environment.
Storage
Storage cost per GB [$]	Specify the cost of the storage-related factors.
Storage switch cost [$]	Specify the cost of the storage switch.
Labor and Facilities Cost
Total labor cost [$]	Specify the total labor cost in your infrastructure. It includes all the labor costs associated with the server, storage, network and additional infrastructure management. For example, the salaries of the IT department members who maintain the on-premises infrastructure.
Storage share of the cost [%]	Depending on your configuration, specify the storage share of the cost as compared to the total labor cost, in appropriate percentage.
Facilities cost [$]	Specify the cost to run the facilities. For example, the cost incurred to maintain the real estate and power.
Custom Cost
Fixed [$]	Specify any other fixed expenses that are not covered as part of previous fields.
Percentage [%]	Specify variable cost in percentages by selecting any of the following options. Additional Cost: Select to apply an additional cost on calculated values. For example, if you think the overall monthly costs are underestimated, and you are not sure cost values for which resources to increase, you can apply a percentage of additional cost. When you apply the additional cost, all Infrastructure Costs per Month values are increased by the input percentage amount. Discount: Select to apply a discount on calculated values. For example, if any of your hardware or software vendors offer you a discount on the product or license, you can add it as a discount to reduce the overall on-premises cost. When you apply the discount, all Infrastructure Costs per Month values are decreased by the input percentage amount.
