What is Kubernetes?
Kubernetes is an open-source Container-as-a-service
(CaaS) framework developed by Google in the previous decade.
Currently, maintained by Cloud Native Computing Foundation, since
Google donated it at 2014, i.e. when a Kubernetes hit 1.0! At its crux, K8s
is a portable, open-source containerization system that lets developers
manage services and workloads. Kubernetes is a complete
containerization orchestration, which provides the ability to run
dynamically scaling, containerized applications, and utilizing an API for
management.

What is Openshift?
OpenShift is a multifaceted, container application platform from Red Hat Inc.
OpenShift is a cloud development Platform-as-a-Service (PaaS) that enables
the developers to develop and deploy their applications on cloud infrastructure.
It is truly conducive in developing cloud-enabled services. The OpenShift
Enterprise 3.2, as the name suggests is an enterprise version and OKD 4 is
open-source. As with most Red Hat products, the upstream version is
essentially a free version with no support or SLA. OKD is a distribution of
Kubernetes optimized for continuous application development and multi-tenant
deployment.

Red Hat OpenShift
OpenShift is an open-source, enterprise-grade platform for container
application development, deployment, and management, based on
Kubernetes. It comes both as a commercial product and a free platform.
Ultimately, it is a commercial software suite included as a feature in many
enterprise cloud service packages.
Developed by Red Hat, OpenShift is written in Go and AngularJS. It
supports Java, Go, Node.js, Python, PHP and Ruby, but it can be extended to
support other programming languages. OpenShift integrates easily with other
DevOps tools, and it’s Open Container Initiative (OCI) compliant for container
hosting and runtime. It can use Docker containers and as it is Kubernetes-
based, will feel familiar to developers coming from those platforms.

What is Kubernetes?
Kubernetes is a free, open-source container orchestration platform currently
maintained by the Cloud Native Computing Foundation (CNCF) and the leading
containerization tool in the industry. Cloud providers like Amazon Web Services
(AWS), Google Cloud Platform, IBM Cloud, and Microsoft Azure include
Kubernetes in their packages.
Written in Go, Kubernetes is a container management tool specialized in
deploying, automating, and scaling applications. It has a fast development
cycle, with new versions coming out every couple of months, being appreciated
by developers for promoting innovation, thanks to a strong community with
many groups invested in the evolution of K8s (Kubernetes short-form name).

OpenShift vs. Kubernetes: which is better?
Like so many other technologies, what is better for some companies is not for others.
Both platforms are excellent for building, deploying, and managing containerized
applications.
Kubernetes is great for intensive-use apps that require regular updates, like games.
OpenShift may be the right option for security-strict, GDPR compliant, heavy-duty
apps like those of institutional or governmental character, or healthcare.
Self-hosted Kubernetes is more complex to install, manage, and monitor without
third-party integrations. OpenShift seems to be an easier option to manage with its
many built-in features,
but it is limited to Red Hat Linux distributions. At the core, OpenShift is built on a
Kubernetes layer but brings additional features that make it a different flavor of
container orchestration.

OpenShift vs. Kubernetes: which is better?
Deployment Base
Kubernetes is flexible when it comes to running on different operating
systems. However, RPM is the preferred package manager, which is a
Linux distribution. It is preferred that Kubernetes be run on Ubuntu,
Fedora, and Debian. This setup allows it to run on major LaaS platforms
like AWS, GCP, and Azure. OpenShift, on the other hand, can be
installed on the Red Hat Enterprise Linux or RHEL, as well as the Red
Hat Enterprise Linux Atomic Host. Thus, it can also run on CentOS and
Fedora.

with its additional feature, makes the deployment of apps easy with the CI/ CD

OpenShift vs. Kubernetes: which is better?
Security
OpenShift has stricter security policies. For instance, it is forbidden to
run a container as root. It also offers a secure-by-default option to
enhance security. Kubernetes doesn’t come with built-in authentication
or authorization capabilities, so developers must create bearer tokens
and other authentication procedures manually.

OpenShift vs. Kubernetes: which is better?
Networking
Kuubernetes does not include a native networking solution and only
offers an interface that can be used by network plugins made by third
parties. OpenShift includes a native networking solution called Open
Switch, which provides three different plugins.

OpenShift vs. Kubernetes: which is better?
Key Cloud Platform Availability
Kubernetes is available on EKS for Amazon AWS, AKS for Microsoft
Azure, and GKE for Google GCP. OpenShift has a product known as
OpenShift Online, OpenShift Dedicated, as well as OpenShift on Azure.

Licensing and Support
Kubernetes is an Opensource solution with the license to modify according to your
requirements, distribute the content and use it as you like. You can even contribute to
their solution in their Github repo. As for support, Kubernetes offer community-based
support. Depends on your use case, community support could be better in many cases.
Whereas Openshift provides you with premium support, where you can get exclusive
help in questions that need to be answered. Openshift comes up with a subscription,
whose cost will increase with the increase in the complexity of your infrastructure. So, it
totally depends upon your budget and scenario, which solution to use.

12.
OpenShift vs. Kubernetes: which is better?
Product vs. Project
While searching for OpenShift vs Kubernetes, one of the major
differences is that one is a product, and another is a project. While
OpenShift is a popular product, Kubernetes is a framework or an open-
source project. OpenShift allows the users to install the product that
offers paid support with a subscription. The subscription is inclusive of
CloudForms, which further helps in enhancing the features of the
product. The users need to renew the subscriptions for their cluster, and
the amount increases with the expansion of the cluster. An OpenShift
tutorial can take you into the depth of the OpenShift concepts.

CentOS as well as Fedora. Kubernetes doesn’t demand any specific requirements

14.
OpenShift vs. Kubernetes: Summary
Since Kubernetes forms the base of OpenShift, one can find a lot of
common aspects between the two. In OpenShift vs Kubernetes.
The above mentioned are some of the significant differences
available. While Kubernetes remains a container platform,
OpenShift comes into being and keeps a tab on the needs of
different enterprises. Through additions to Kubernetes, the existing
infrastructure can evolve to the next phase. But it requires much
effort and skills.
This makes OpenShift a better choice because of its built-in
features. The manageable rollout, logging, and monitoring options
keep OpenShift a step ahead of Kubernetes. The networking
solutions, as well as the integrating and installing process, also
account for OpenShift to be more demanding. Although both are
quite similar, the out-of-the-box features of OpenShift make a big
