Detailed Pricing Breakdown
Explore the specifics of how Azure Cosmos DB is priced:
Throughput (RUs)
Request Units (RUs) are the throughput provisioned or consumed by your database operations. The cost is based on the amount of RUs per second (RU/s) you provision or the RUs consumed.
| Region | Provisioned Throughput (RU/s) | Serverless (RU) |
|---|---|---|
| Global | $0.00001 / RU/s | $0.0001 / RU |
| East US | $0.000008 / RU/s | $0.00008 / RU |
