Define an SLO for Checkout
How would you define an SLO for a checkout service?
Practical scenario
A checkout service has no SLO. Current availability is about 99.4% and p95 latency is about 800 ms. Leadership wants "three nines" because a competitor advertises it.
What it tests
- • Whether the candidate picks an SLI that reflects user experience
- • Understanding of measurement point and window as design choices
- • Whether targets come from data or from wishes
