Question

A mid-sized retailer currently runs a self-managed relational database on IaaS virtual machines. The DBA team spends significant time on OS patching, database engine upgrades, backup scripting, and replication configuration. Leadership asks the cloud architect to reduce operational overhead while keeping the same database engine, but they are concerned about losing low-level control. As part of a cost-benefit analysis, which trade-off should the architect present as the PRIMARY consideration when recommending a move to the provider's managed PaaS database service?

Accepted Answer

The managed PaaS service transfers operational tasks like patching, backups, and replication to the provider, reducing labor cost but removing OS-level and some engine configuration control.

Answer

The managed PaaS service eliminates all shared responsibility, making the provider fully accountable for data classification and access control.

Answer

The managed PaaS service always costs less per month than IaaS regardless of workload, so cost is never a trade-off.

Answer

The managed PaaS service requires the retailer to switch to a different database engine, so application code must be fully rewritten.
