The above example sets up two different subsets based on label selectors, configures a global loadBalancer policy for the frontpage service, but overrides it for the v2 version. Backyards (now Cisco Service Mesh Manager) collects upstream metrics like latencies, throughput, RPS, or error rate from Prometheus, and provides a summary for each gateway. With this design, we can easily establish communication and extend our clusters as needed. Version specific policies can be specified by defining a named subset and overriding the settings specified at the service level. In the gateway resource, the selector refers to Istio's default ingress controller by its label, in which the key of the label is istio and the value is ingressgateway. Use NGINX Ingress Controller with Istio Service Mesh. NGINX Ingress Controller can now be used as the Ingress Controller for applications running inside an Istio service mesh. This allows you to continue using the advanced capabilities that NGINX IC provides on Istio-based environments without resorting to any workarounds.
