What Is OpenShift and Its New Features (Complete Guide)

Red Hat OpenShift is an enterprise-grade, Kubernetes-based application platform designed to help organizations build, deploy, and manage containerized applications at scale. Developed by Red Hat (an IBM company), OpenShift extends upstream Kubernetes with opinionated defaults, integrated security, and production-ready tooling.

Unlike “raw” Kubernetes, OpenShift provides a complete application platform—combining container orchestration, developer workflows, security controls, and operations automation—so teams don’t have to assemble and maintain dozens of separate components.

Key Facts at a Glance

• Type: Enterprise Kubernetes Application Platform (PaaS)
• Core Technology: Kubernetes + Enterprise Linux
• Deployment Models: Self-managed, cloud-managed, and fully managed
• Primary Use: Running containerized workloads in hybrid and multi-cloud environments
• Target Audience: Enterprises, DevOps teams, platform engineers, and developers

Background and Positioning

OpenShift originally started as a Platform-as-a-Service (PaaS) focused on simplifying application deployment. As Kubernetes became the industry standard for container orchestration, OpenShift evolved into a full Kubernetes distribution plus an application platform.

Today, its positioning is clear:

“Kubernetes for the enterprise—secure by default, automated by design.”

OpenShift is aimed at organizations that want the power of Kubernetes without the operational complexity of stitching together networking, security, monitoring, ingress, registries, and lifecycle management on their own.

OpenShift Architecture and Core Components

• api-server
• etcd
• kcm
• kubelet
• CRI-O
• SDN
• Control-plane
• Worker

OpenShift builds on upstream Kubernetes but adds enterprise-grade components and automation.

Core Architecture Elements

• Hardened Kubernetes
  • Secure defaults (non-root containers, SCCs)
  • Opinionated cluster configuration
• Cluster Operators
  • Specialized controllers that manage platform components
  • Automatically handle install, upgrade, scale, and recovery
• Integrated Networking
  • Built-in ingress and routing
  • Software-defined networking with policy enforcement
• Built-in Container Registry
  • Image storage and lifecycle management
• Role-Based Access Control (RBAC)
  • Strong multi-tenancy and least-privilege access
• Unified API Surface
  • Consistent Kubernetes APIs across all environments

This architecture allows OpenShift clusters to be self-healing, upgradeable, and consistent across platforms.

Developer and DevOps Experience

One of OpenShift’s biggest strengths is its focus on developer productivity and DevOps efficiency.

Developer Features

• Source-to-Image (S2I): Build containers directly from source code
• Templates, Helm, and Operators: Multiple deployment models
• Web Console & CLI (oc): GUI and automation-friendly tooling
• GitOps Integration: Declarative deployments using Git as the source of truth

DevOps & Platform Engineering Benefits

• Integrated logging, monitoring, and metrics
• Built-in CI/CD pipeline integrations
• Centralized policy enforcement
• Reduced operational overhead compared to DIY Kubernetes

Instead of managing a patchwork of tools, teams work within a single, integrated platform.

Hybrid and Multi-Cloud Focus

Hybrid and multi-cloud is a core design principle of OpenShift.
OpenShift runs consistently on:

• On-premises data centers
• Private clouds
• Public clouds (AWS, Azure, GCP, etc.)
• Edge environments

This enables organizations to:

• Standardize on one Kubernetes platform
• Move workloads between environments with minimal changes
• Avoid vendor lock-in
• Meet compliance and data residency requirements

Why Enterprises Choose OpenShift

Organizations adopt OpenShift because it delivers:

• Consistency: Same platform everywhere
• Security: Enterprise-grade, policy-driven controls
• Automation: Operator-based lifecycle management
• Productivity: Faster developer onboarding and delivery
• Scalability: Proven at large enterprise scale

For regulated industries, global enterprises, and teams running mission-critical workloads, OpenShift provides a trusted Kubernetes foundation.

Conclusion

Red Hat OpenShift is more than just Kubernetes—it is a complete enterprise application platform. By combining Kubernetes with built-in security, automation, and developer tooling, OpenShift enables organizations to focus on building applications instead of managing infrastructure.

With its strong hybrid and multi-cloud strategy, modern security posture, and continuously evolving feature set, OpenShift has become a leading choice for enterprises looking to standardize and scale their container platforms with confidence.
