As of now, Tessell supports only one type of licensing option for Oracle.
Bring Your Own License (BYOL)
In this licensing model, you can use your existing Oracle Database licenses to run Oracle deployments on Tessell. Ensure that you have the appropriate Oracle Database license (with Software Update License & Support) for the DB service compute class and Oracle Database edition you wish to run under this licensing model. You must also follow Oracle's policies for licensing Oracle Database software in the cloud computing environment, either on AWS or Azure.
