The document discusses how SLOs (Service Level Objectives) can be used for continuous performance optimizations of Kubernetes workloads. It provides an overview of common performance issues like the N+1 query problem. It then describes how Keptn can be used to automate testing, analysis and remediation based on defined SLOs. Keptn establishes an event-driven workflow that orchestrates monitoring, deployments, testing and SLO evaluations to help optimize performance and ensure SLIs meet defined objectives. Real-world examples are provided of how Keptn has been used by companies to validate release readiness and environment stability.
