Optimize Terminology

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

Following are terms used in the context of the Optimize module that you should be familiar with.

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.

cloud service provider (CSP)

A company that offers cloud-based services and solutions. Examples are Amazon Web Services (AWS) 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 Migrate). 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 or Azure), with an associated billing account. The billing account can represent a single account or multiple accounts, if doing consolidated billing.


Equates to an entity in VirtualWisdom or an element in CloudWisdom.


GovCloud is an AWS cloud offering that restricts administrative access to U.S. citizens only. The region meets the requirements for U.S. International Traffic in Arms Regulations (ITAR), and allows users to move Controlled Unclassified Information (CUI) into the cloud. See the official AWS Guide for more information.

IAM role

An IAM role is an AWS identity with associated permissions policies. This role is used by Optimize to communicate with AWS. The role provides temporary security credentials that only apply for the role session.

Management Account Permissions

Grants read-only access to collect billing files from a single AWS S3 bucket that can be located in a management account.

Migrate module

The Migrate module is a component in the Virtana Platform that de-risks and accelerates application or workload migrations for public or private clouds.

Minimal Cost Permissions

Grants read-only access to collect CloudWatch performance metrics and billing files. It is limited to only the AWS services for which Virtana Platform Optimize provides cost reports.


An organization typically equates to a company, but can relate to departments or other components of a company. An organization is the entity under which specific workloads will be grouped for migration and optimization, and to which a user and projects belong. Users can belong to more than one organization.


Configuration parameters that a user can apply to a data source. In Optimize, policies define the optimization constraints for Idle Resources and Right Sizing reports.

report filter

User-customized filters (tags and attributes) applied to data sources. They can be used to segment environments to identify savings within a subset of your environment.

Standard Permissions

Grants blanket read-only access to collect CloudWatch performance metrics and billing files from AWS S3.


A key/value pair or simple string used as an organizational label applied to resources. You create tags in your cloud service provider account.

unblended costs

The sum of the applicable rates times usage (rates x usage) for each shared resource in consolidated accounts. Unblended costs represent the usage costs on the day they are charged to you.

Virtana Platform

A cloud-agnostic platform offered by Virtana that is composed of several modules to help migrate, optimize, and manage workloads in cloud and hybrid environments.
