Move SQL Server to the cloud. With HA intact.
Tessell migrates and manages SQL Server on AWS and Azure with multi-AZ high availability, BYOK encryption, and full DBA control, in your own cloud account. No application rewrites.
SQL Server estates don't move themselves
SQL Server tends to sprawl across business units and data centers, each managed a little differently, each with its own licensing, HA setup, and operational habits. Moving it to cloud usually forces a choice between losing capabilities your team depends on and accepting constraints on how you configure and operate it. Tessell migrates your SQL Server estate without that trade-off. You keep multi-AZ high availability, full control over images, parameters, collation, and security groups, and your own encryption keys, then run the whole estate from one control plane afterward, on AWS or Azure.
How Tessell Solves It
Migrate without the risk
Lift and Shine is Tessell's phased, no-rewrite migration methodology. Tessell stands up your SQL Server workloads in the target cloud, validates them, and cuts over on your schedule, with production kept live until you switch. Applications connect to the same endpoints after migration.

Manage as one estate
After cutover, every SQL Server instance is managed from one control plane: provisioning, patching, monitoring, point-in-time recovery, HA and DR, native backups, and cloning, with consistent governance across clouds and business units. The Availability Machine provides continuous backup and point-in-time recovery, with logsweep running every five minutes.
