A broken SLO with no owner can take longer to remediate and is more likely to recur compared to an SLO with an owner and a well-defined remediation process. To avoid this, start the SLO discussion early in the design process.

When the word “performance” is heard, most people immediately think of speed. Measurements refer to specific data points, such as the number of seconds it takes to process a request. Wait time: Sometimes called average latency, wait time refers the amount of time a request spends in a queue before it gets processed.
