Quality gates are benchmarks in the software delivery lifecycle that define specific, measurable, and achievable success criteria a service must meet before moving to the next phase of the software delivery pipeline. Automating quality gates creates reliable checks and balances and speeds up the process by avoiding manual intervention.

Tracing as a foundation Logs, metrics, and traces are the three pillars of observability. Metrics communicate what’s happening on a macro scale, traces illustrate the ecosystem of an isolated request, and the logs provide a detail-rich snapshot into what happened within a service. Is this an anomaly or are we dealing with a pattern?
