Cockroach Labs Estate economics What idle nodes, provisioned bytes and peak-sized bills cost, worked out from your estate.

Describe your estate, then read what changes

Cluster virtualization, disaggregated storage, and a bill that follows the workload: seven pages, one claim each, and a summary that adds them up.

Clusters

An average, not a uniform estate: sizes scatter around it, odd for quorum. 30 nodes in total.

How it's sized

Demand through the day 40%

The shape sets the peak everything is sized against, and headroom is what you buy above it - each cluster for its own peak, since that's what a provisioned estate buys, so nothing here is pooled. Both describe the estate you have; what a pooled estate would be run at is set in step 1, where it's the argument.
