Site reliability engineering (SRE) has become crucial as companies increasingly rely on cloud automation and digital transformation to enhance business operations, necessitating a team effort to effectively implement service-level objectives (SLOs). SLOs enable site reliability engineers to set goals aligned with business priorities, yet categorizing service levels and consolidating monitoring data pose significant challenges due to siloed data and tool overload. A single observability platform can provide consistent visibility, but it must include native SLO capabilities and agreed-upon tools before deployment. Additionally, correlating performance metrics with user experience is vital to understanding user interactions and identifying potential issues, while a data-driven approach helps set realistic SLO targets. The ownership of SLOs varies by context, often involving development teams for non-production applications and SRE teams for broader environments, with the ultimate aim of enhancing customer experience and aligning IT efforts with business objectives.
