Another important aspect is that SLOs should be carefully balanced. Setting them too high may set the team up for failure, while overly lenient objectives can lead to complacency. Striking this balance is a crucial part of the SREâs responsibilities.
"SLOs are like a compass. It tells you where you need to go, but the journey is up to you."
Error Budget Policy
Closely tied to SLOs is the Error Budget Policy. This concept revolves around the idea that failure is not only acceptable but expected. An error budget defines the acceptable level of unreliability a service can have without adversely affecting user experience. In other words, itâs a way to quantify how much downtime or performance degradation is tolerable given the objectives set by SLOs.
For example, if an SLO dictates that a service should be 99.9% available, this corresponds to a error budget of about 40 minutes per month. This figure gives teams the freedom to innovateâpushing new features or modifications into production that might cause short-term disruptionsâas long as they stay within these defined bounds.
Benefits of an Error Budget Policy include:
