Cost Management Terminology

Some terms used in Virtana Platform are common words but with meanings specific to the module being used.

amortized costs

Distributes any up-front fees and monthly installments evenly across the reservation period.


Metadata created and assigned by your cloud service provider (CSP) that defines a property of a resource. You can use attributes in Virtana Platform to filter items to include in or exclude from a report.

blended costs

The averaged rates of the reserved and on-demand instances that are shared by multiple member accounts. The blended view recognizes relative usage of reserved instances, so accounts that make more use of reserved instances are allocated a higher proportion of those overall costs.

change request

The ability to submit ticket requests to modify your CSP environment based on recommendations from Idle Resources or Right Sizing Reports. The requests are configured as part of a policy in Cloud Cost Management and submitted to a change management system, such as Jira or ServiceNow.

cloud service provider (CSP)

A company that offers cloud-based services and solutions. Examples are Amazon Web Services (AWS), Google Cloud Platform (GCP), and Microsoft Azure. Also called cloud provider.

compute instance

An individual instance of a virtual machine (VM) or a physical server node that can be associated with an application or a move group (in Workload Placement). A compute instance can belong to only one application or move group.

consolidated billing

The grouping of multiple accounts into a single billing account, with one main "parent" account and related linked "children" for billing purposes. The child account information rolls up to the parent account. Equivalent to an AWS "organization".

Cost Explorer

A visualization tool that provides a view of your spend across different AWS Services. Use to get a clearer perspective of weekly, monthly, and quarterly spending trends for your business.

data source

An integration instance (such as AWS, Azure, or GCP), with an associated billing account. The billing account can represent a single account or multiple accounts, if doing consolidated billing.
