The Importance of Service Level Objectives
Site Reliability Engineering has introduced many organizations to the concept of Service Level Objectives and Error Budgets.
Nobl9 aims to help organizations adopt the SLO framework by streamlining the SLO creation process and making it simpler to monitor whether the objectives are being met.
SLOs are essentially a target set for a given system’s desired availability over time. Tracking SLO adherence is dependent on SLIs, which are a way to measure if an SLO is being met or not. If a system or service is not meeting its SLO, there are consequences such as performance degradation, outages, or impact on customers. SLOs balance the possible negative repercussions and the lack of availability to determine a reasonable uptime goal for that service, with the downtime afforded in that SLO as the error budget.
