Difference Between Kubernetes Vs Open Shift

Containers serve as a form of virtualization for operating systems. It accommodates everything from microservices to extensive applications within a single container. These containers encapsulate essentials like executables, binaries, libraries, and configurations.

Unlike traditional server or machine virtualization, containers do not include complete OS images. Hence, they are more portable, lightweight, and resource-efficient.

Kubernetes and OpenShift are two well-known platforms for building containers. Understanding the idea of containerization is crucial when comparing Kubernetes and openshift. Containers involve combining distinct applications to facilitate efficient creation, management, and deployment across diverse infrastructures.

This approach empowers businesses with enhanced flexibility, scalability, and streamlined development of applications that result in acknowledged benefits.

Unraveling the Kubernetes and Openshift comparison can be intricate, given that Kubernetes is integral to OpenShift. A product by Red Hat, OpenShift is frequently referred to as the “Enterprise Edition of Kubernetes.” Making the right choice is still difficult, even though the selection of container orchestration options is limited.

When compared to OpenShift, which seamlessly integrates with Kubernetes, Kubernetes automates the deployment, scaling, and operation of applications while increasing application efficiency.

In this article, we will discuss in detail the two important platforms, Kubernetes and Openshift. We will also look into their major differences and features. Stick with us till the end to learn more in detail about these two most important platforms of DevOps.

What Is Kubernetes?

Over a decade ago, Google’s developers established Kubernetes. It is an open-source technology that revolutionized container-as-a-service (CaaS). Kubernetes stands as a versatile, open-source solution for containerization, enabling developers to automate the entire lifecycle of containers, encompassing deployment, management, scaling, and networking.

This platform is a foundation for efficiently handling the expansive scale management of distributed applications housed within containers. With Kubernetes, developers determine the desired deployment locations for their software, and the platform undertakes most deployment and management tasks.

Kubernetes provides application developers with several benefits, including self-monitoring, process automation, container load balancing, and storage planning. It is now housed within the Cloud Native Computing Foundation.

For streamlined management and exploration, Kubernetes organizes containers into logical clusters. Importantly, it operates seamlessly across diverse landscapes, spanning cloud environments, on-premise systems, and even hybrid cloud configurations.

The lasting impact of Kubernetes lies in its ability to empower developers with the tools they need to harness the full potential of container applications, regardless of the infrastructure upon which they are deployed.

Features of Kubernetes

Now, let us check out some features of Kubernetes in the following table.

Features of Kubernetes
Feature	Description
High Availability	Kubernetes offers automated failover and load-balancing features that guarantee application availability, even during hardware or software failures.
Self-Healing	Kubernetes keeps track of container and application health and can automatically restart or replace failed containers, ensuring uninterrupted application operation.
Portability	Kubernetes provides a uniform and transportable environment for deploying containerized apps across diverse infrastructure providers, like public clouds and data centers.
Extensibility	Kubernetes boasts extensive extensibility, including a comprehensive set of APIs that enable custom controllers and operators to automate unique infrastructure tasks.

What Is OpenShift?

OpenShift is crafted by Red Hat, a cloud development platform offered as a Service (PaaS). It is beneficial for developing cloud-based applications.

Under the PaaS model, Red Hat’s OpenShift emerges as a user-friendly open-source cloud platform committed to the smooth development, testing, and preparation of applications before their cloud deployment.

This reliable platform makes it easier to use an integrated development environment (IDE) for the development and deployment of containers in the Docker format. OpenShift accommodates diverse application frameworks like Node.js, Ruby, Python, Perl, and Java.

The platform’s automated and manual scalability mechanisms meet the requirements of container applications to ensure top performance.

OpenShift operates as an abstraction layer that includes key virtualization principles. Its essence revolves around virtualization, a concept that constructs virtual systems rather than physical replicas.

This foundational concept is essential to OpenShift’s architecture. Also, its role is instrumental in streamlining cloud-based development and facilitating the realization of resilient, scalable applications.

Features of Openshift

Some of the important features of the Openshift are given in the table here.

Features of Openshift
Feature	Description
Developer Experience	OpenShift prioritizes a user-friendly experience for developers, offering streamlined tools and workflows that simplify building, testing, and deploying applications.
Security	OpenShift ensures the security of containerized applications through various measures such as role-based access control (RBAC), image scanning, and container isolation.
Automation	OpenShift simplifies containerized application management with automation functionalities like automatic scaling, rolling updates, and self-healing capabilities.

Differences Between Kubernetes And OpenShift

The two advanced platforms have some major differences between kubernetes and openshift, which we will discuss in the table below.

Difference Between Kubernetes and Openshift
Aspects	Kubernetes	OpenShift
Definition	Kubernetes is an open-source containerization platform that allows developers to manage services and their workloads.	Openshift is a cloud-based platform that allows developers to develop and deploy their applications on the cloud infrastructure.
Deployment	Can be installed on various platforms and Linux distributions.	Requires specific platforms like RHELAH, Fedora, or CentOS.
Platform	It is an open-source framework called Container-as-a-Service (Caas). It was launched by Google.	It is a cloud development platform known as Platform-as-a-Service (PaaS).
Security	No built-in authentication/authorization.	Stricter security policies have a secure-by-default option
Support	Large active community, and broader framework/language support.	Smaller support community, primarily from Red Hat.
Releases and Updates	Approximately four releases per year.	Around three releases per year, fewer concurrent updates.
Networking	Supports third-party network plug-ins.	Provides Open vSwitch with native plug-ins.
Templates	Offer more flexible Helm templates.	Less flexible and user-friendly templates.
Image Registry	No integrated image registry supports private registries.	Integrated image registry that works with DockerHub/Red Hat.
CI/CD	No complete out-of-the-box solution integrates with CI/CD tools.	Offers a certified Jenkins container for CI.
User Experience	Complex web interface, which requires additional setup for access.	A user-friendly online console with a simple, one-touch login page.

Kubernetes Vs. Openshift Which One Should You Use?

As we compared Kubernetes and Openshift, it revealed that the two widely adopted container management systems each have distinct attributes, advantages, and limitations. Kubernetes does well at automating diverse aspects of application deployment, scaling, and overall operations. In contrast, OpenShift operates as a containerization platform, utilizing Kubernetes as its foundation and optimizing application performance and resource utilization.

For those familiar with containerization fundamentals and having an understanding of Kubernetes, the inclination might lean slightly towards Kubernetes due to its superior flexibility when compared to OpenShift.
