When it comes to Oracle licensing, Tessell currently supports only BYOL, as explained below :
Bring Your Own License (BYOL): This option allows you to use your existing Oracle database licenses to run on Tessell. If you have a ULA with Oracle that includes the Oracle database, you can use your existing licenses with Tessell. You'll need to provide your own Oracle Database license, as well as any necessary options or features. You'll also need to ensure that you're following Oracle's licensing rules and regulations. For more details, refer to Oracle’s guide to Licensing Oracle Software in the Cloud Computing Environment.
