Work out slo target instantly with clear inputs, formula shown and shareable results.
An error budget is simply (1 - SLO) multiplied by the period, expressed either as time or as failed requests. 99.9 percent over 30 days is 43.2 minutes or 0.1 percent of requests. Its purpose is to make reliability a shared decision: while budget remains, shipping is allowed; when it is exhausted, reliability work takes priority automatically rather than by argument.
Error budget
budget = (1 - SLO) x period; in minutes = (1 - SLO) x days x 1440; in requests = (1 - SLO) x requests per day x days
No. A perfect target leaves no budget for change, so every deployment becomes a violation. The SLO should sit just above what users actually need.
The multiple of budget consumption relative to spending it evenly across the period. A burn rate of 14.4 exhausts a 30-day budget in about two days, which is a standard fast-burn alert threshold.
