Cost considerations and Infrastructure set up with new Business Hub

Hello All,
we are currently exploring KNIME as an option to other Self Service ETL tool at our org. If things work out in terms of features and other aspects of the platform, the Business Hub will be installed in our AWS tenant. I wanted to hear from existing customers of Business Hub at a high level, what all different cost consideration we need to take into account apart from Business Hub and license cost.

AWS Redshift is out primary data source along with some on-premise SQL Server, Oracle DBs. A good amount of workflows also use flat files as data source which we need to move somewhere to cloud so KNIME can access it.

Can anyone who has done medium to large scale deployment help me here?

Thank you
