Daily Term: SLO

SLO

A Service Level Objective (SLO) is a specific, measurable target for service performance, often part of an SLA. For example, an SLO might target 99.95% availability for an API, meaning it can be down for no more than 4.32 minutes per month. SLOs guide operational goals and are monitored using metrics like uptime or latency. They help balance reliability and cost but require setting realistic targets to avoid over- or under-engineering systems.
