You need to define Service Level Objectives (SLOs) for a high-traffic multi-region web application.
Customers expect the application to always be available and have fast response times. Customers are
currently happy with the application performance and availability. Based on current measurement,
you observe that the 90th percentile of latency is 120ms and the 95th percentile of latency is 275ms
over a 28-day window. What latency SLO would you recommend to the team to publish?
A/B? I’d rule out D and C since they’re way looser than current metrics, which doesn’t seem right if users expect fast responses. Between A and B, B matches what customers already experience, so it feels safer.
A/B? B matches current experience exactly, which customers like, but A sets a tighter goal that could push for better performance. Not sure if that risk is worth it given current satisfaction.
B/C? Option B fits what users are already happy with, so it seems safe to avoid raising expectations. But C might give a bit of breathing room for spikes while still being close enough to current experience to not disappoint. A seems too strict since it’s below current metrics and might be unrealistic. D feels like it relaxes too much and could lead to worse user experience. I’d probably go with B if you want to be conservative, but C could work if you want to avoid unnecessary pressure on the team.
B, matches what's currently observed and accepted by customers.
