It is possible to split the billing of the kinesis firehose into the different ones that we had

You would need to use Cost and Usage Report for this.

For large accounts/organization we generally recommend creating the report on your Management Payer account (in case with Organizations with multiple accounts), and set it up with hourly granularity, include resource IDs, and use Parquet format so you could later easily query it with Athena.

Though, if you have only one account, with limited amount of services that you use, you might decide that initially (to start with) you could create the report in CSV format, use either daily or monthly granularity, but still include resource IDs.

The reports are delivered to S3 bucket that you choose or create. Note that it may take around 24 hours for the first report to get delivered, and it's not retroactive (you will only see the data in that report starting from this month and going forward). Then, if it's created in CSV format, you can just download it from your bucket and investigate. However, we recommend setting it up in Parquet format so that you could then easily query the report in Athena service, simply using SQL. It will contain columns related to all services that you use, including the column "resource ID". So, you'll be able to see how much each resource (within each service that you use) costs you.
