Junho Lee is a Solutions Architect who has worked at Rockplace Inc. since 2014. The document compares Kubernetes (k8s), OpenShift, and Google Kubernetes Engine (GKE). k8s is an open-source container cluster manager originally designed by Google. OpenShift is Red Hat's container application platform based on k8s. GKE provides k8s clusters on Google Cloud Platform. Both OpenShift and GKE add services on top of k8s like app stores, logging, monitoring and technical support. The document outlines the key components, architectures and capabilities of each platform.
