Managed services versus self-hosting trade-offs
WHAT IT TESTS: cost and control trade-offs. OUTLINE: managed services cut operational burden and speed delivery but cost more and limit control; self-hosting offers full control and tuning at the price of patching, scaling, and reliability work.
WHAT IT TESTS: whether you reason about total cost and control, not list price. ANSWER OUTLINE: managed services like RDS or Lambda handle patching, backups, failover, and scaling, reducing operational toil, speeding time to market, and improving reliability, but they cost more per unit, constrain configuration, and risk lock-in. Self-hosting on VMs gives full control, custom tuning, and potentially lower raw cost, but you own patching, high availability, backups, scaling, and on-call.
