On-Premises Cost Governance - Cost Calculation Policies
The Cost Calculation Policy page in the Virtana platform provides an overview of defined policies related to cost governance. These policies define the rules and parameters for mapping usage metrics to meter cards and applying aggregation rules for resources such as compute, storage, and GPU. The platform mandates the presence of at least one cost calculation policy, which can be created manually or, if absent, is automatically generated by a scheduled cron job. This dual mechanism guarantees that cost calculations are never disrupted, even in newly deployed environments or after all existing policies are deleted.
Cost calculation policies are highly customizable, allowing organisations to tailor cost computations to their specific needs by incorporating parameters like region, vendor, and resource type. The default policy, automatically created when needed, provides a broad and reliable baseline, ensuring continuity in cost management until custom policies are defined.
The following is a detailed breakdown of the cost calculation policy process:
Cost Calculation Definition: Describes the policy applied for cost calculation. It helps Administrators identify the purpose of the policy.
Created Time: Indicates the exact date and time when the policy was initially created. The created time provides a timestamp for when the policy was introduced into the system. Accurate timestamps are critical for tracking policy changes and ensuring compliance.
Created By: Specifies the user who created the policy.
Last Updated Time: Displays the most recent time the policy was updated. Keeping track of the latest updates is essential to ensure that the most recent version of the policy is in effect.
Last Updated by User: Indicates the user who last modified the policy.
