Key Differences Between Open Shift and Kubernetes in 2025

Kubernetes: What is it?

Kubernetes is an open-source platform developed to automate the deployment, scaling, and management of containerized applications. Initially created by Google and later donated to the Cloud Native Computing Foundation (CNCF), Kubernetes has evolved to become the de facto standard for container orchestration in the industry, making it an essential skill for those pursuing a Career in Azure Cloud. It simplifies the complexity of managing large-scale containerized environments, providing developers with a robust, flexible platform that can run applications across various infrastructures, such as public, private, or hybrid clouds.

At its core, Kubernetes automates key operational tasks such as application scaling, load balancing, and self-healing. One of the standout features of Kubernetes is its automated scaling, which adjusts application resources based on demand. For example, if an application experiences increased traffic, Kubernetes can automatically add more instances of containers, and when demand decreases, it scales down to optimize resource usage. This dynamic scaling ensures that applications are always running efficiently and cost-effectively.

• Kubernetes also incorporates self-healing capabilities, which are essential for maintaining application uptime and availability. If a container fails or crashes, Kubernetes detects the issue and automatically replaces the failed container, ensuring that the application remains functional without any manual intervention. This resilience is critical for maintaining high availability in production environments.
• Finally, Kubernetes is designed with multi-cloud and hybrid cloud support in mind. It allows applications to be deployed across different cloud providers or in on-premises data centers, enabling organizations to avoid vendor lock-in and giving them the flexibility to choose the infrastructure that best fits their needs. With Kubernetes, organizations can build, deploy, and manage applications in a consistent manner, regardless of the underlying cloud environment.

Kubernetes vs. Open Shift: Key Differences

Installation and Setup

• Kubernetes: Installation of Kubernetes can be complex and time-consuming. Users must ensure proper configurations for networking, storage, and logging tools. Though cloud providers like Google Cloud (GKE) and AWS (EKS) offer managed Kubernetes services, self-hosted clusters still require significant setup.
• Open Shift: OpenShift simplifies the installation process with automated deployment tools, which aligns with the principles of the DevOps Maturity Model by streamlining development workflows and enhancing automation across the software delivery pipeline. Red Hat offers an installer that automatically configures the Kubernetes components, easing the burden of setup for users. Open Shift’s integrated platform reduces the complexity of managing separate services.

Security Features Comparison
• Kubernetes: Kubernetes offers role-based access control (RBAC) and secret management for securing applications, but users are responsible for configuring these features. Kubernetes itself does not enforce strict security protocols by default.
• Open Shift: Open Shift takes a more security-centric approach. It comes with integrated SELinux (Security-Enhanced Linux), secure default configurations, and more robust user access control, making it suitable for environments with stringent security requirements. Additionally, Open Shift enforces container security policies, such as ensuring containers run as non-root users by default.

User Interface and Experience
