Hi @nguyenphu123, could you please describe your use case? The number of instances you declare in a deployment obj (number of replicas), for example: link |

My nginx ingress controller currently running with 2 pods and 2 replicas. I also have 2 services with 2 pods and 2 replicas each that are running behind the ingress controller. |

Hi @nguyenphu123 there's no set formula to select number of replicas/pods but the general guideline is to use horizontal pod scaling to match the demand. Have a look at https://kubernetes.io/docs/tasks/run-application/horizontal-pod-autoscale/ |

To apply this to NIC, you can use
controller.autoscaling...helm parameters https://docs.nginx.com/nginx-ingress-controller/installation/installing-nic/installation-with-helm/#configuration
