Honestly, a lot of the time I don't understand why a lot of businesses use k8s.
At my company especially, we know almost exactly what our traffic will look like from 9am-5pm. We don't really need flexible scaling, yet we still use it because the technology is hyped. Similar to cloud, we certainly don't need to be spending as much as we do, but since everyone else is on or migrating to the cloud, we are as well.
Kubernetes is not really meant primarily for scaling. Even kubernetes clusters require autoscaling groups on nodes to support it, for example, or horizontal pod autoscalers, but they are minor features.
The benefits are pooling computing resources and creating effectively a private cloud. Easy replication of applications in case of hardware failure. Single language to deploy applications, network controls, etc.
