This is a practical comparison based on real production use, not vendor marketing.
Quick Comparison
| Feature | Kubernetes | OpenShift |
|---|---|---|
| Vendor | CNCF (open source) | Red Hat (IBM) |
| Base | Upstream Kubernetes | Kubernetes + enterprise additions |
| Console | Dashboard (basic) | OpenShift Console (excellent) |
| CI/CD | External (ArgoCD, Flux, Tekton) | Built-in Pipelines (Tekton) |
| Registry | External | Built-in integrated registry |
| Security | Pod Security Standards | SCCs (more restrictive) |
| Cost | Free (infra only) | Subscription required |
| Support | Community or vendor | Red Hat support included |
When to Use Vanilla Kubernetes
- Maximum flexibility: Choose every component yourself
- Cost-conscious: No license fees — pay only for infrastructure
- Managed services: EKS/GKE/AKS give you supported Kubernetes without OpenShift cost
- Community ecosystem: Helm charts, operators, and tools target upstream K8s first
When to Use OpenShift
- Enterprise platform: Complete application platform out of the box
- Red Hat ecosystem: RHEL, Ansible, Satellite, ACM integration
- Regulated industries: Certified for government, healthcare, and financial workloads
- Developer experience: Source-to-Image, built-in CI/CD, developer console perspective
- Support contract: Single vendor support for the entire platform stack

My Recommendation
Use vanilla Kubernetes (managed via EKS/GKE/AKS) for flexibility and cost savings. Use OpenShift when you need an enterprise-certified platform with integrated CI/CD, registry, and Red Hat support. Book a consultation to choose the right platform.
