As software delivery tasks traditionally performed at the end of the software delivery lifecycle – such as testing and deployment – have shifted to the beginning of the lifecycle, developers are now working with Kubernetes more directly. Dynatrace enables teams to specify SLOs, such as latency, uptime, availability, and more.

A broken SLO with no owner can take longer to remediate and is more likely to recur compared to an SLO with an owner and a well-defined remediation process. To avoid this, start the SLO discussion early in the design process.
