Tessell is a multi-cloud DBaaS that runs Oracle, PostgreSQL, MySQL, and SQL Server on AWS and Azure using high-performance compute and flat-rate, instance-based pricing. This comic-style guide walks through the real challenges enterprises face when migrating databases to cloud, where hyperscaler DBaaS pricing becomes unpredictable, and how a different cost and control model changes the picture.
What is inside
Why hyperscaler DBaaS pricing models, particularly IOPS metering, create unpredictable cloud database costs and what a flat-rate alternative looks like
How Tessell runs Oracle as a managed service natively on Azure, without requiring Oracle Cloud Infrastructure
The difference between proprietary snapshots and native database backups, and why it matters for compliance and portability
How automated data masking, self-service data access, and policy-based governance work within a unified control plane
What "Data At Your Terms" means in practice: bringing your own cloud account, security policies, and IT governance to Tessell
How one-click DR failover and inter-region replication work, and how Tessell can serve as a low-risk starting point for cloud database migration
Who is this for
IT leaders and database teams evaluating cloud database migration or DBaaS adoption. The guide walks through the cost, control, and complexity challenges of running databases in the cloud, using a comic-style narrative format. Use it to start the cloud database conversation across technical and business teams. It is not a step-by-step migration playbook.
