Defining and managing on-premises costs

Use the On-premises Costs 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.

On-premises Costs tab

The cost of an instance is computed based on various factors such as compute, storage, network, virtualization system, database, operating system, and so on. The default cost rates of these factors are available out-of-the-box when you install the product. You can modify the default cost rates in the On-premises Costs tab. You can also specify generic cost that the predefined factors do not account for.

For a detailed procedure, see Defining on-premises costs.

The default cost estimates of these factors are estimated by using the Cost Estimator input values.

You can view the updated costs of the instances on the Bill details page. For example, on the By Cloud Service page.

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.

  1. Log on to the TrueSight console.
  2. Expand the left navigation pane and select Cloud Cost Control.
     The Cloud Cost Control page is displayed.
  3. Click Settings icons.png Settings > Settings.
    The Settings page is displayed. The On-premises Costs Definition tab is open by default. 

  4. Click the Settings action menu and select Edit.
    The Settings page is refreshed and the fields in the infrastructure cost 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 one or more virtualization platforms as well as for the Windows platform.

    These infrastructure cost values are calculated using the values provided in the Cost Estimator Inputs section. 

    These fields are disabled for editing but the values are re-calculated automatically when you modify any of the values in the Cost Estimator Inputs section.ccc_onprem_cost.PNG

    If required, you can override the calculated values by directly modifying the unit costs in the infrastructure cost per month panel.

  5. 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 so on, 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. Click Copy values to inputs to copy these values in the respective fields of that panel. You can modify these values as per your requirement to re-estimate the costs. The infrastructure cost values are re-calculated automatically when you modify any of the values in this section.

Review the following tables to understand the input fields provided to calculate your monthly cost rates.

Physical Servers

Field

Description

Number of servers

Specify the number of physical servers available in your on-premises infrastructure.

Number of servers with Windows OS

Specify the number of physical servers with Microsoft Windows available in your on-premises infrastructure.

Specify the average number of CPUs for a physical server.

Memory per server [GB]

Specify the average memory capacity for a physical server, measured in gigabytes.

Storage per server [GB]

Specify the average storage provisioned for a physical server, measured in gigabytes.

Cost of the virtualized system [$]

Specify the cost of the virtualized server in dollars

Virtualization platform

Specify the monthly cost per server for one or more virtualization platforms:

  1. Click + Add Platform.
  2. Select a platform from the list.
  3. Specify the values for the following fields.

vCPUs per VM

Specify the average number of virtual CPUs for a virtual machine.

Operating System

Field

Description

Operating system

Select an operating system from the list.

Click + Add Operating System to specify the monthly cost of more operating systems.

Cost ($ per server)

Specify the monthly cost for the selected operating system.

ccc_cost_os.PNG

Information

The cost for the operating system is not considered for Hyper-V systems that are running the Windows operating system because the cost is already considered as part of the Hyper-V cost.

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 [Mb/s]

Enter the monthly wan bandwidth rate that you are using in your environment.

Monthly WAN bandwidth rate per Mbps) [$]

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.
