Google Kubernetes Engine vs OKD

Google Kubernetes Engine is a managed environment for running containerized applications. It manages the Kubernetes control-plane life cycle for each cluster, from creation to deletion. Teams using Autopilot can hand node provisioning, scaling, scheduling and infrastructure management to Google, while users who prefer can manage nodes themselves. Autopilot also includes automatic capacity right-sizing and per-pod pricing. GKE supports GPU and TPU workloads and connects with AI Hypercomputer for machine-learning and high-performance computing. The product page states that clusters can reach 65,000 nodes. Security features include visibility into configuration issues and risks, agentless scanning for critical vulnerabilities, workload isolation through GKE Sandbox and hardware-based encryption for data in use with Confidential GKE Nodes. Fleets and Teams help organize clusters and workloads across teams. It also supports conformant attached Kubernetes clusters and says applications can run unmodified on on-premises hardware or in public cloud. Windows Server node images and containers are unavailable in Autopilot. A free tier and trial are listed, with a $9/mo starting price.

OKD is a free, self-hosted Kubernetes platform for managing applications and clusters at scale. It extends Kubernetes with more than 100 preinstalled Operators and includes a web console, authentication, image registry and tooling, monitoring, networking, node configuration and upgrades, and Operator management. Cluster nodes run an immutable operating system managed through cluster APIs. OKD states that it is 100% compliant with Kubernetes, with additional patches for some advanced features, and its defaults include hardened configuration. The platform supports autoscaling, rolling updates, and policy controls. Installation works on bare metal, virtualization platforms, and cloud platforms, using installer-provisioned or user-provisioned infrastructure. Integrated deployments cover areas such as GitOps, service mesh, virtualization, and storage. Downloads include stable releases and nightly builds for installer and client tools. The installation guide provides signed-checksum verification instructions; its examples cover Linux and macOS client and installer archives and Windows client archives. OKD directs users to Kubernetes Slack’s #okd-dev channel and a Google Group. It describes uses for technologists, students, and OpenShift contributors and partners.
