Dynatrace’s AIOps platform uses causation-based, deterministic AI to spot potential slowdowns and outages before they occur and to trigger automated actions that prevent failures. “Instead of the trigger being a failure, our trigger is a point of time before failure,” Swofford says.

ITOps teams use more technical IT incident metrics, such as mean time to repair, mean time to acknowledge, mean time between failures, mean time to detect, and mean time to failure, to ensure long-term network stability. This is the number of failures that affect users’ ability to use an application by the total time in service.

These could include issues with vulnerable and outdated components, injections, and software and data integrity failures. Effective incident detection and response goes through phases of isolating affected systems, analyzing the impact, identifying the root cause, and taking appropriate remedial actions.

One major Kubernetes advantage is its self-healing, continually making repairs and addressing failures that affect applications’ integrity. While teams use both namespaces and projects to isolate resources within a cluster, OpenShift’s projects provide additional features. That said, Kubernetes has some drawbacks.
