You&rsquo;ve gathered your users&rsquo; feedback and want to introduce a new feature that will drive engagement. However, you&rsquo;re cautious about not disrupting active users with potential downtime if the new feature causes an overload on your servers.</p> <p>Currently, you have a Kubernetes cluster with the Ingress-Nginx controller and a blue-green deployment setup. You can switch 100% of traffic to the new version immediately — but you&rsquo;d rather divert only a small portion first and monitor the effects before fully committing.
