SLI, SLO, SLA, and Error Budget are core components of Site Reliability Engineering that work together to manage and improve service reliability. SLIs are the metrics used to measure service performance. SLOs set the target values for those metrics. SLAs are formal agreements with customers based on SLOs, and include consequences if targets aren't met. Teams can use tool now to monitor and track these indicators in real time. The Error Budget is the margin of failure allowed before breaching the SLO. Applying these concepts helps balance reliability and innovation, improving user satisfaction and aligning IT with business goals.
