Cloud Engineer interview question · Most asked
Tell me about a time you reduced cloud cost or improved reliability. How did you measure it?
Summary
Use STAR: the situation and baseline numbers (monthly cost, incidents, RTO), the specific actions you took (tagging, rightsizing, commitments, multi-AZ fixes, restore tests), trade-offs and who you involved, and the measured result (cost per month, availability, recovery time), plus how it was sustained.
Longer Answer
