Service Level Objectives


Service Level Objectives (SLOs) are targets for Service Level Indicators (SLIs), representing the desired level of service reliability. They are crucial for aligning reliability goals with business objectives and customer expectations.


(Achieved SLI Value / SLO Target) * 100


If the SLO target for uptime is 99.9% and the achieved uptime SLI is 99.5%, the SLO achievement is (99.5 / 99.9) * 100 = 99.6%.
