Several clients from Brazil frequently complain that MongoDB is expensive. One of the reasons is the need to create separate clusters (even M10-sized clusters) for development and/or staging for each production cluster.

One alternative they are using to reduce MongoDB costs is to share DEV and/or staging clusters among multiple teams. However, this introduces another challenge: how to split these costs internally between different departments.

To address this demand, which has been raised by several clients—including Ambev, Anhanguera, DASA, and Digibee—my suggestion is for Atlas to provide a way for customers to see the cost per database within a cluster. In other words, if a cluster hosts five databases and costs USD 25K in total, it should be possible to identify the share of that USD 25K attributable to each database.
