The data plane stays in your cloud account - your networks, your keys, your compliance posture. No black box. No vendor lock-in.
Run every Oracle edition, feature, and version on one control plane, with enterprise HA and DR and Oracle-tuned infrastructure, in your own cloud account.




"Lack of resiliency and recoverability was formerly our biggest issue. With Tessell, it is no longer a concern."

Tessell uses a white box architecture: the data plane - all databases, snapshots, backups, transaction logs, monitoring metrics, and logs - resides in your cloud tenant. The control plane, hosted on Tessell's tenant, holds only metadata and never has inbound access to your data.
Security and ComplianceDeployed in your subscription, resource group, and tenancy.

No inbound connections from Tessell's control plane. Only outbound HTTPS calls to Tessell REST APIs.

Tessell cannot create, update, or delete any network or key outside the workspace you define.

Tessell's access is restricted to a specific resource group within a specific subscription. It cannot access any resources outside its own.

Azure AD, Okta, G-Suite. All clients use REST APIs with revocable tokens.









Bring your existing Oracle license or let Tessell source them. EE, SE2, and all Oracle versions within Oracle's active support lifecycle are fully supported — with automated upgrades so you never hit end-of-support.






We'll review your Oracle estate, identify the right cloud and infrastructure configuration, and show you a realistic migration path - no obligation.
