Containerization is the latest jargon today, in the world of IT, primarily to develop and deploy apps in an accelerated manner. In the era of serverless computing and container technology, containers have become highly popular for a long time now. With the increase in popularity, there is an increase in the complexity levels of large containerized applications. Here comes the need for efficient container management platforms that can help in easily managing containerized applications. Today, Kubernetes and OpenShift are two big names in this arena and have become major players in the container revolution. Popular, effective, scalable, robust, and simplistic – both have their own user community to boast of.
Here is a certain feature list that is present in both – Kubernetes as well as OpenShift:
Here is the first glance at both the container management platforms and their introductory parameters:
Factors |
Kubernetes |
OpenShift |
Developers | Cloud-Native Computing Foundation (CNCF) | Red Hat |
Programming Language | Go | Go, Angular JS |
Category | Cluster management software | Cloud computing, PaaS |
License | Apache License 2.0 | Apache License 2.0 |
Released In | 2014 | 2011 |
Let us go through the nuances of Kubernetes and OpenShift, understanding them further and knowing their strength areas:

Originally born at Google, Kubernetes was released in 2015 as an open-source tool for all. Later, Google handed over the entire project to Cloud Native Computing Foundation (CNCF), operated by the Linux Foundation. Kubernetes is an open-source container as a service (CaaS) orchestration system that automates deploying, scaling, and managing containerized apps, speeding up the development procedure. Since it has been handled by Google taskforce, there is a certain level of maturity that exists.
“OpenShift is a family of containerization software developed by Red Hat. Its flagship product is the OpenShift Container Platform—an on-premises platform as a service built around Docker containers orchestrated and managed by Kubernetes on a foundation of Red Hat Enterprise Linux.”

Red Hat® OpenShift® is supported Kubernetes for cloud-native applications with enterprise security
Developed by Red Hat, OpenShift is a containerization software solution whose prime product is the OpenShift container platform, a PaaS managed by Kubernetes. OpenShift has been often called “Enterprise Kubernetes” by its vendor – Red Hat. Red Hat OpenShift is a CNCF Certified Kubernetes offering, indicating interoperability between OpenShift and other Kubernetes offerings. It has been written the Go programming language and AngularJS. It possesses an Apache License. The original version facilitates developers to develop and deploy apps to the cloud and appends tools over a Kubernetes core to fasten the development and deployment process.
Subsequently, OpenShift is grounded on Kubernetes and hence, there is a lot of similarity between both. Yet, there are some variances between both platforms, depending on important parameters.
Parameters | Kubernetes | Openshift |
Point of Origin | It is an open-source project/framework, not a product | It is a product with many variations. All OpenShift products are open source and derived from OKD, an open-source project maintained by Red Hat. |
Installation | Can be installed on almost any Linux distribution | Has limited options when it comes to installation |
Key Cloud Platforms | Available on GKE on Google GCP, EKS on Amazon AWS, and AKS on Microsoft Azure | Red Hat offers OpenShift Online and OpenShift Dedicated as multi- and single-tenant managed offerings on AWS. Red Hat and Microsoft jointly support an additional managed cloud offering, Microsoft Azure Red Hat OpenShift. |
Security & Authentication | Well defined but not as stringent as OpenShift | Stricter security policies and authentication models |
Usage of templates | Kubernetes Helm templates are flexible and easy to use | OpenShift templates are less user-friendly and flexible |
Releases | It almost has 4 released a year | It falls behind in schedule with mostly 3 a year |
Deployment | It has Deployment objects implemented through controllers | It has DeploymentConfig objects implemented through logic |
Updates | Deployment supports many concurrent updates at a time | DeploymentConfig does not support concurrent updates |
Management of Container Images | There is no specific feature for the management of container images | ImageStreams is ideal for easy management of container images and is unique to OpenShift |
CI/CD | CI/CD is possible with Jenkins but it is not integrated within the tool | Seamless CI/CD integration with Jenkins available |
Learning Curve | Kubernetes does not have a very easy web console and hence a tad difficult for novices | OpenShift has a very useful web console and hence becomes attractive and easy for newbies |
Initial Rollout | It is a little difficult for an initial rollout since it has additional components to go along | Has an easy rollout since it acts as a complete cluster solution with minimal add-ons |
Enterprise Usage | Kubernetes caters to all categories but has nothing specific to enterprises | OpenShift was designed keeping in mind the enterprise and has many components meant for that |
Networking | Brings along interfaces that can be utilized by 3rd party network plugins | Has OpenvSwitch, a native networking solution that gives 3 varied plugins |
Web User Interface | Separate installation for dashboards, manual creation for the login page | Login page already available, easy creation of resources through a form |
Both are open-source; both have a common base with Kubernetes at the core of OpenShift; both are popular, and both aim to facilitate faster application development. Because of its unique features and reliance on Kubernetes, OpenShift does have the added advantage of easy installation. Kubernetes is experienced and well-proven; it does require a proper strategy for installation.
Kubernetes is a standardized version and is available on an increased number of platforms than OpenShift. But, OpenShift has many inbuilt components that make app containerization faster and effective. On top of both, comes a crucial decision – choosing the IT service provider who has the experience, expertise, and infrastructure to help you with the entire application development lifecycle. That holds more crucial and hence should be thought of, very sincerely.
