Understanding OpenShift

OpenShift is a container platform developed by Red Hat, a leading provider of open-source solutions. It aims to provide a comprehensive platform for organizations to develop, deploy, and manage containerized applications efficiently.

OpenShift originated from Red Hat’s earlier Platform-as-a-Service (PaaS) offering called OpenShift Online, which was released in 2011. Over time, OpenShift evolved into a more robust and flexible platform that embraced containerization and adopted Kubernetes as its orchestration engine. Today, it is available as OpenShift Container Platform for on-premises deployments and OpenShift Dedicated for managed cloud environments.

Core features and components of OpenShift

OpenShift offers a rich set of features and components that enhance the Kubernetes experience. Some of the core features and components include:

  • Container Runtime
  • Build and Deployment Automation
  • Integrated Developer Experience
  • Image Registry
  • Service Mesh

OpenShift supports multiple container runtimes, including Docker and CRI-O, providing flexibility in choosing the underlying technology.

OpenShift includes tools for automating the build and deployment processes, such as Source-to-Image (S2I) and Kubernetes-native build capabilities.

OpenShift provides developers with a user-friendly interface and tools for easy application development, testing, and collaboration.

OpenShift includes an integrated image registry to store and manage container images, allowing for versioning, security scanning, and efficient image distribution.

OpenShift integrates with popular service mesh solutions like Istio, enabling advanced traffic management, security, and observability for microservices architectures.

Overview of OpenShift’s architecture

OpenShift’s architecture is built on top of Kubernetes and extends it with additional components. At its core, OpenShift employs the same concepts of pods, services, and deployments as Kubernetes, but it introduces higher-level abstractions to simplify application management. These abstractions include Projects, Applications, and Routes.

OpenShift uses a master-node architecture where the master components handle the orchestration and management of the cluster, and the worker nodes execute the containers. The master components include the API server, controller manager, and scheduler, while the worker nodes host the pods and execute the containerized applications.

Advantages of using OpenShift for container orchestration

OpenShift provides an intuitive web-based console and command-line tools that simplify application development, testing, and collaboration, making it easier for developers to work with containers.

It’s integrated tools for build automation, deployment, and scaling help streamline operations and reduce manual effort, enabling faster application delivery. Also OpenShift offers built-in security features such as role-based access control (RBAC), image scanning, and network policies, ensuring secure container environments. It also helps organizations comply with regulatory requirements.

OpenShift leverages Kubernetes’ scaling capabilities to scale applications horizontally based on demand, ensuring high availability and efficient resource utilization.

OpenShift provides a robust platform for deploying and managing complex enterprise applications, enabling seamless scaling, fault tolerance, and easy integration with existing systems.

It’s automation capabilities, integrated tools, and container-based workflows make it an ideal platform for implementing DevOps practices and CI/CD pipelines.

Understanding Kubernetes

In 2014, Google released Kubernetes as an open-source project, allowing organizations to benefit from its container orchestration capabilities. Since then, Kubernetes has gained immense popularity and has become the industry standard for managing containers at scale.

Kubernetes offers a comprehensive set of features and components that enable efficient container orchestration. Some of the key features and components of Kubernetes include:


The basic building block of Kubernetes, a pod represents one or more containers that are tightly coupled and share the same resources, such as network and storage.


Kubernetes services provide a stable network endpoint to access pods, allowing for load balancing and service discovery within the cluster.

Replication Controller/ReplicaSet

These components manage the desired number of pod replicas, ensuring high availability and fault tolerance by automatically scaling and replacing failed instances.


Deployments provide declarative updates to pods and replica sets, enabling seamless rollouts and rollbacks of application changes.


Kubernetes namespaces provide a logical separation and isolation of resources within a cluster, allowing multiple teams or projects to share the same cluster securely.

Overview of Kubernetes’ architecture

Kubernetes follows a master-worker architecture, where the master components manage and control the cluster, while the worker nodes execute the containers. The key components of the Kubernetes architecture include:

API Server: The central control point for managing and interacting with the cluster. It exposes the Kubernetes API, allowing users to control the cluster and its resources.

Controller Manager: This component ensures that the desired state of the cluster matches the actual state by monitoring and managing various controllers, such as the ReplicaSet controller and Deployment controller.

Scheduler: The scheduler assigns pods to worker nodes based on resource requirements, constraints, and availability, ensuring efficient utilization of cluster resources.

etcd: A distributed key-value store that stores the cluster’s configuration data, providing reliable data storage and consistency for the entire cluster.

Kubelet: The primary agent running on each worker node, responsible for managing and executing containers as part of pods.

Advantages of using Kubernetes for container orchestration

Kubernetes allows organizations to scale applications horizontally by adding or removing containers, ensuring high availability and efficient resource utilization. Kubernetes’ declarative approach to deployments enables seamless application rollouts and rollbacks, reducing the risk of errors during updates.

This project monitors the health of containers and automatically restarts or replaces failed instances, ensuring the continuous availability of applications. Kubernetes optimizes resource allocation, allowing multiple applications to run efficiently on a cluster while effectively managing resource utilization.

Kubernetes is cloud-agnostic, enabling applications to run consistently across different cloud providers or on-premises environments, promoting portability and avoiding vendor lock-in.

Use cases and industries where Kubernetes excels

It’s important to note that Kubernetes’ flexibility and scalability make it applicable to a wide range of industries and use cases.

As an example, let’s take a look at how GART implemented IoT device management using Kubernetes. They leveraged Kubernetes to effectively manage and scale their IoT edge devices. By utilizing Kubernetes, they achieved seamless deployment of containerized applications on edge devices, centralized management and monitoring of the devices, and streamlined software updates across their IoT network.
