Domain 1 · Understand Usage and Cost
Every dollar has an owner.
Allocation distributes shared costs to the teams, products, and cost centers that actually drive them. Walk-phase maturity expects 80%+ attribution; CloudMonitor gets you there with virtual tags and shared-cost splits — not an enterprise re-tag project.
The problem
Tagging gets you halfway. Then it stops.
Tag coverage decays.
Coverage starts at 70% and drifts down. Resources spin up tagless on Friday and stay that way.
Shared costs sit unallocated.
Networking egress, shared databases, central log workspaces — the bill lands somewhere central and stays there.
Reorgs break the chart.
Every restructure invalidates last year's allocation tree. Trends become incomparable.
How CloudMonitor answers
Attribution without re-tagging the estate.
Virtual tags.
Rule-based tags layered over raw resource tags — fix attribution in the tool when fixing it in Azure would take a quarter.
Shared-cost splits.
Split shared costs by headcount, consumption, or fixed-ratio. Network and observability charges land on the team that drove them.
Hierarchical cost groups.
Roll resources up to product, then BU, then segment. Reorg the tree without losing last year's trends.
Unallocated visibility.
The bucket you can't ignore: an explicit "unallocated" view, sized and trended, so leftover spend gets a meeting, not silence.

Allocation in CloudMonitor
Tags, cost groups, and attribution coverage.
Cost allocation
Every dollar mapped to an owner.
Partition Azure spend across cost groups, watch coverage climb toward the 80%+ that makes chargeback defensible, and reconcile it back to the raw FOCUS total every night.
Unallocated spend
See what is leaking before it compounds.
The spend sitting outside every cost group, sized and trended, then broken down to the exact resources and purchases with no owner, each ready for a rule.
Cost groups
Roll spend up the hierarchy you actually run.
Every cost group with its spend, budget, forecast, and owner in one table. Reshape the tree in hours, not weeks, without losing last year's trends.
