CostFormation Rule Types

There are 5 types of CostFormation rules:

📘

What's Most Important

80% of all CostFormation logic is built using a combination of Group and GroupBy rules

General Rules

1. Group - You define the conditional logic for the element
2. GroupBy - You want to leverage existing metadata within the infrastructure (tags values usually)
3. Metadata - Convenience rule if you have a lot of “fuzzy” / “contains” logic you need to implement. You can always implement this logic with Group rules as well, it will just be more verbose

Allocation Rules

• Background - Allocation rules let customers define logic that takes a set of shared spend / resources and split it out across a business context (products, teams, etc..). For a more detailed description of allocation, please refer to CloudZero’s documentation

4. AllocateByRules - Allocation rule where you define the sharing logic within CostFormation
5. AllocateByStreams - Allocation rule where you send in external usage telemetry to CloudZero’s cost allocation API to drive the sharing logic. Examples of external usage telemetry might be # of API calls, RDS DB Size, query duration in milliseconds, etc.
