Tessell migrates and manages Oracle databases on AWS, Azure, and GCP with no application changes and typically 25 to 50 percent lower total cost than self-managed alternatives, proven by customers. Migrate your entire Oracle estate, then run it from a single control plane.
Most enterprises have already moved the rest of their estate to cloud. Oracle is what's left, and it is what keeps the data center running and on the books. The result is paying for the old environment and the new one at the same time, often several million dollars a year in data center cost that cannot be shed until Oracle moves. Delaying compounds it. Every quarter on-premises is another quarter of infrastructure you own and cloud benefits you are not capturing, and the window before the next renewal cycle or data center exit deadline is shorter than it looks. Tessell moves the Oracle workloads that make a clean exit possible, and optimizes your Oracle investment in the process.

Lift and Shine is Tessell's phased, no-rewrite migration methodology. Tessell builds a standby of each Oracle database in the target cloud using Oracle Data Guard, keeps it continuously in sync, validates everything, and cuts over on your schedule. Production stays live until you switch, and your applications connect to the same endpoints afterward, with no schema rewrites or recompilation. Start a standby in the cloud, validate everything, cut over on your schedule. Zero data loss. Near-zero downtime.

| Migration is the start. Tessell runs Oracle from there.| A database has to be provisioned, kept current, watched, and kept running when something goes wrong. After cutover, Tessell manages the full operational lifecycle of your Oracle estate from one platform.
