FOCUS column
AvailabilityZone
The availability zone within the region the resource ran in, where the provider reports it. Zones matter for resilience design and for some pricing, such as inter-zone data transfer, and a zone-level view shows whether a workload is spread as intended.
Example
Three compute rows for one cluster carry zones “a”, “b” and “c”, showing the node pool is spread across the region.
Where it comes from, per export
The export column that feeds AvailabilityZone in each format the platform ingests, and the transform applied. A format with no row does not carry the column; the value is then absent rather than guessed.
| Export | Source column | Transform |
|---|---|---|
| AWS Data Exports, FOCUS | AvailabilityZone | as is |
| Azure Cost Management, FOCUS export | AvailabilityZone | as is |
| Azure Cost Details (actual cost) | AvailabilityZone | as is |
| Azure Cost Details (amortized cost) | AvailabilityZone | as is |
| Google Cloud detailed billing export | Not carried | — |
How Runcost uses it
Runcost surfaces zone on the resource drill-down and in transfer-cost analysis, where inter-zone traffic is a common surprise.
