One pattern I keep seeing in Kubernetes environments is how often external load balancers become the default for everything.
It works in the beginning.
But once clusters start growing, exposing internal APIs, dashboards, monitoring systems, and private services publicly starts creating unnecessary complexity pretty quickly.
In many cases, the traffic never needed internet exposure at all.
That’s usually where internal load balancers start making much more sense.
Instead of routing traffic publicly, services stay reachable only inside the private network while still remaining accessible across workloads inside the cluster.
In practice, this usually ends up being much cleaner for internal infrastructure services.
I found this walkthrough useful because it keeps the setup practical and straightforward:

External load balancers are often used as the default in Kubernetes, but many internal services never need public internet exposure. Internal load balancers keep services reachable only within the private network, reducing unnecessary complexity as clusters grow. A practical walkthrough for setting up an internal load balancer in Civo Kubernetes is referenced.
