In one line

Replication instances bill by the hour from creation to deletion, whatever the tasks are doing.

What gets missed

There is no data transfer charge on the DMS node itself, which lulls people. The instance is the meter and it runs until deleted. Zero-ETL integrations are the exception: priced per GB, CDC far above full load.

Find it on your bill

Bills the same way

These services turn exactly the same meters, so what you learn here transfers.
