Overview

Dimensions let you slice your cloud spend along the lines that matter to your business—teams, products, environments, and more.
Within each dimension, segments capture the exact set of resources that belong to every category you define.

​
Core Concepts

​
Dimensions

A dimension is a top-level category—“cost per X”. Common examples:

  • Business Units – Marketing, Engineering, Sales
  • Product Lines – Web Platform, Mobile Apps, API Services
  • Cost Centers – R&D, Operations, Customer Support
  • Usage Types – Production, Development, Testing

​
Segments

Segments are the specific buckets inside a dimension. They group resources that meet criteria you choose:

  • In a Teams dimension, segments might be Frontend, Backend, Data Science.
  • Resources lacking clean tags can still be captured by mixing rules—e.g. tag team:frontend or name prefix fe-.

Once assigned, the segment name becomes a consistent identifier everywhere in Pelanor, even if underlying tags are messy or missing.

​
Coverage

Each dimension shows a coverage %—the share of spend already assigned to segments. Higher coverage equals clearer, more complete cost visibility.

Creating a New Dimension

Basic Details

Enter a name and description, then switch to the Segments tab.

  1. Select properties – choose tags, names, service types, etc. Multiple properties are allowed.
  2. (Optional) Add filters – narrow by region, account, service, and so on.
  3. Segment editor
    • Available Values lists every discovered value with its current cost.
    • Actions:
      • Create Segment – each selected value becomes its own segment.
      • Segment Together – merge selected values into one segment.
      • Add to Existing – move values into an already-created segment.

Click Apply Creation Rules to lock in the bulk configuration.

​
3. Segment Management

After bulk creation, the preview shows every segment with estimated cost and a resource graph.

From here you can:

  • Add Segment – create one manually.
  • Edit filters on any segment.
  • Re-order execution to control cost allocation when resources match multiple segments.
  • Search / sort or view Unallocated resources for gap hunting.

​
Using Dimensions

  • Reports & Dashboards – group or filter any chart/table by your dimension or by individual segments.
  • Strategies – some allocation strategies reference dimensions; see the Related Strategies tab for links.

Best Practices

AreaTips
Property selectionPick fields that map cleanly to your org structure. Combine multiple when no single property covers everything.
Segment namingUse clear, consistent names that mirror your business language.
CoverageMonitor the coverage percentage and investigate unallocated spend. Aim for the highest practical coverage.
MaintenanceReview segments periodically and adjust rules as your organisation evolves.

​
Limitations & Notes

  • A segment cannot be empty—it must include at least one resource.
  • Segments created via bulk rules are deleted only by removing the rule itself.
  • Segments linked to workspaces must be detached before deletion.
  • Execution order matters when a resource could qualify for multiple segments.
