The cloud-native landscape is at an inflection point. While Kubernetes and microservices once dominated the conversation, a growing chorus of organizations is sounding the alarm: complexity doesn’t scale. As experienced system administrators, we’ve watched clients wrestle with Kubernetes’ operational overhead, skyrocketing costs, and the “microservices hangover.” Now, a pragmatic shift is underway, toward solutions that prioritize simplicity,...| Pieter Bakker
