Cost dimensions allow you to slice and dice your cost information to provide insights on spend and potential savings. This page describes the RightScale-generated cost dimensions, but there are also bill-based dimensions and custom dimensions.

RightScale-generated dimensions are created by the RightScale platform, combining data from across providers into a standardized form. Today there is really only one such dimension, covered below.


The Category dimension in Optima is generated by the RightScale platform based off of data in each cloud. RightScale evaluates each line item in the bill and applies a set of rules to place each line item in a given high-level category. The set of category values are as follows: Admin, AI, App-Service, Applications, Compute, Database, IOT, MachineLearning, Marketplace, Network, Other, RI/CUD, Storage, Streaming, Support

To determine which category a given cost falls into, a set of prioritized rules are applied to each cost. The rules use various data elements from each provider to divvy up the cost. The following sections detail the rules that are used for each cloud provider.

Note: In the below table, the * character matches any value. For example, EBS:* matches any value for the column that begins with EBS:.
