Why not just hire more SREs or buy another platform?

Throwing headcount at alert fatigue multiplies toil. Another tool without behavior change is shelfware. The ROI came from making the safe path automatic (guardrails) and making flow habitual (coaching).

Can we do this without Istio?

Yes. You can implement circuit breakers/timeouts with NGINX, Linkerd, or even app-level libraries. Istio/Envoy made it easier to standardize in Kubernetes, but the principle holds: finite retries, backoff, outlier ejection.

We’re regulated (PCI/SOC2). Does GitOps pass audit?

Yes. ArgoCD provides immutable history, diff views, and RBAC. Pair it with policy-as-code (Gatekeeper) and you get repeatability and auditability auditors actually like.

What if teams resist trunk-based?

Start with flags and canaries to remove fear, enforce small PRs with CI checks, and set a rollback SLA. Most resistance melts once the first painless rollback happens.

How did you attribute revenue lift?

Datadog RUM + conversion funnel showed fewer drop-offs during peak hours. We compared against prior-year cohorts and controlled for marketing mix; the delta aligned with reduced user-visible errors and faster recovery.
