https://www.linkedin.com/in/brianeh/ An https://www.nginx.com/resources/glossary/kubernetes-ingress-controller probably seems like just another technology widget in the https://kubernetes.io/ realm. An ingress controller does this by quietly assuming many of the capabilities that other tools or solutions provide.

You must deploy and configure an ingress controller application (using the Kubernetes API) to implement the rules defined in ingress resources. In other words, you really need to deploy an ingress controller to leverage the existing resource and object structure of Kubernetes.

If your ingress rules are poorly designed and your pods under-resourced, then an ingress controller can slow down apps.
