The article delves into the evolving perceptions and applications of Kubernetes beyond its conventional role as a container orchestrator. It explores the spectrum between utilizing Kubernetes as a comprehensive platform for managing applications and infrastructure, and leveraging it merely as an interface to interact with cloud services like AWS. Through various deployment models, the piece illustrates the flexibility Kubernetes offers, from fully controlled environments to hybrid approaches integrating cloud-native services, and ultimately, to a vision where Kubernetes acts as a control plane with managed services as the data plane.
