Amazon Elastic Kubernetes Service vs OKD

Amazon Elastic Kubernetes Service (EKS) is a managed Kubernetes service for building, running, and scaling production applications across cloud, on-premises, and edge environments. It manages Kubernetes control-plane availability across three AWS Availability Zones and replaces unhealthy control-plane nodes automatically. Applications can run on Amazon EC2 or AWS Fargate. EKS Auto Mode automates provisioning for compute, storage, and networking, along with scaling, operating-system patching, and add-on management. Hybrid deployments can use Hybrid Nodes, AWS Outposts, or EKS Anywhere. EKS remains compatible with upstream Kubernetes applications and tools, and integrates with IAM role-based access control, VPC pod networking, and Application Load Balancers. EKS Capabilities provides managed Argo CD for GitOps across clusters. There are no minimum fees or upfront commitments, but worker resources and related traffic are billed separately. Standard version support is $0.10 a month, billed per cluster hour.

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.
