Question

A retail company runs an Azure Cosmos DB for NoSQL container configured with autoscale throughput at a maximum of 20,000 RU/s. During most of the day, actual utilization stays near 2,000 RU/s, but a nightly batch job briefly pushes usage to the configured maximum. The finance team asks the developer to explain how billing works for this autoscale configuration so they can forecast costs. Which statement correctly describes the hourly billing behavior?

Accepted Answer

You are billed each hour for the highest RU/s the container scaled to within that hour, with a minimum floor of 10% of the maximum (2,000 RU/s).

Answer

You are billed a flat rate for the full 20,000 RU/s maximum every hour regardless of actual utilization.

Answer

You are billed only for the RU consumed per request, identical to serverless pricing, with no throughput floor.

Answer

You are billed for the average RU/s consumed across the entire hour, so brief spikes have negligible cost impact.
