RDS Custom

Related: RDS, EC2

Is an RDS Instance but some system level access as in EC2 is preserved. Fills the gap between RDS and EC2 DB. You can connect with SSH, RDP, Session Manager.
Supports only MS SQL/Oracle.

Actually present on account, you will see EBS volumes and EC2 instances.

For customisation of RDS Custom requires pausing RDS Custom Database Automation at the time customisation is made
