One platform to migrate, manage, and modernize your databases
One control plane for your entire database estate, on every cloud.
Tessell engineers migrate and support you, on a platform your team controls.
Databases run in your cloud account. Data never leaves your governance.
Oracle, SQL Server, and open source, on any major cloud. No lock-in.
Trusted by leading enterprises
"Air traffic control for your databases"
Dan Van Tran, CTO, Collectors
Every estate has a path forward.
Whether you are moving to the cloud or already there, Tessell meets your databases where they are and takes them further.
Migrate to the cloud of your choice, with the database of your choice
Your Oracle and SQL Server estate is the last big thing to move, and the riskiest, because it carries the deepest dependencies and the heaviest operational load. Tessell moves it in phases, with no application rewrites, no forced cutovers, and zero data loss, then keeps running it long after.
High bills, only one cloud, data in the wrong region, and every upgrade still a manual job?
Whether you're moving off another managed service or done carrying the upkeep yourself, Tessell gives you a fully managed platform in your own account, with the HA, DR, and automation you'd otherwise build and maintain yourself, across the clouds and regions you choose, and no lock-in.
Migrate. Manage. Modernize.
Move your estate without the risk
Your Oracle and SQL Server estate is the last big thing to move, and the riskiest. Tessell moves it in phases you control, one wave at a time, in a method we call Lift and Shine: stand up a replica, validate, and cut over on your schedule. No application rewrites, no forced cutovers, no data loss at cutover.

Fully managed. Your keys, your account.

Why enterprises move, and stay
Tessell has migrated mission-critical database estates - hundreds of databases, Fortune 500 companies, hard deadlines - and kept them running long after. Migration is only the start of the relationship. A fully managed, modern database estate is what it becomes.
Lower cost. Less risk. No lock-in.
Outcomes, not projections

Everything you need to run databases at scale
High Performance
NVMe-backed storage delivering up to 2M IOPS and 10x performance, with predictable instance-based pricing.
Availability and DR
Multi-AZ high availability with automatic failover, plus cross-region disaster recovery managed through the Availability Machine.
Data protection
Automated snapshots, point-in-time recovery, and instant clones for dev and test, with policy-driven retention across the estate.

Automation and IaC
API-first and Terraform-native, with self-service provisioning and managed patching and upgrades.
Observability
Real-time metric visibility with alerting and dashboards across the estate, connected to your existing monitoring stack.
Elastic scale
Scale compute and storage on demand, with read replicas and continuous right-sizing as workloads change.
Data ecosystem
Stream operational data to your lake or warehouse with near-real-time pipelines, including Microsoft Fabric and OneLake, from your own account.
Every engine, every cloud
Oracle including RAC and Exadata, SQL Server with Standard Edition HA, PostgreSQL, and MySQL, on every major cloud.
Get your weekends back
Tessell is not here to replace your database team. It automates the work no DBA enjoys, patching, backups, HA, DR, and failovers, so nobody comes in on a Friday or Saturday night to keep the lights on, and your team spends its time on work that adds value to the business.
No more Friday night patching
Patching, backups, HA, and DR run on their own, supervised by a dedicated engineering team. On-call stops being a lifestyle and weekends stop being work.
Automate the toil, not the DBA
Tessell removes the repetitive operations, not the people who understand your databases. Your team stays in control of the estate.
More time for high-value work
With the day-to-day operations handled, your DBAs put their expertise where it counts most, on performance, architecture, and the work that adds real business value.
Built for every role on your team.

Effortless database management at scale
Provisioning and patching that used to take our team weeks now happens in minutes. The automation is a genuine game-changer.Reliability we can count on
We have not had a single unplanned outage since migrating. Backups and failover just work, exactly as promised.Cut our cloud database costs significantly
Right-sizing and running in our own VPC gave us full cost control. We reduced our TCO by more than half in the first year.
Bring us your hardest estate. We will show you the path, the numbers, and the team behind it.
Built to co-sell
Tessell runs in your customer's own cloud account and stays neutral to engine and cloud. We work alongside the hyperscalers and global system integrators from first scoping call to production.
