Openshift Vs Kubernetes : What is the Difference? 2023 Edition
For instance, a video game development company can benefit from this feature when they need to develop games that are compatible with a variety of operating systems. OpenShift enables the game developer’s programmers openshift consulting to use their favorite tools while developing games for different systems. This results in effective container usage, without forcing the company’s developers to use tools they aren’t familiar with.
- Three years ago, deployment of the OpenShift cluster wasn’t easy.
- Kubernetes offers a dashboard as an add-on, which is not a core part of Kubernetes.
- On the Kubernetes side, even though it now offers Kubernetes RBAC, you still have to set everything up by yourself, including other security protocols like IAM and OAuth.
- Since then, containerization has risen in popularity, further abstracting away underlying system components, and becoming the cornerstone of microservices architecture.
- Platforms like these, including Red Hat’s OpenShift, make container use viable for enterprise applications.
- These are fulfilling the base infrastructure functions such as networking, authentication, etc.
- It’s fast, enables self-service provisioning, and integrates with a variety of tools.
Container-native virtualization allows administrators and developers to run and manage virtual machine workloads alongside container workloads. It allows the platform to create and manage Linux and Windows virtual machines, import and clone existing virtual machines. It also provides the functionality of live migration of virtual machines between nodes. Projects are custom resources used in OpenShift to group Kubernetes resources and to provide access for users based on these groupings. Projects can also receive quotas to limit the available resources, number of pods, volumes etc.
Main OpenShift components
The platform offers a paid subscription for administration and infrastructure management. Consequently, users enjoy dedicated support, complete with periodical upgrades. Alternately, OpenShift’s open-source version, also called OKD, is a community edition platform that is limited to only ‘self-support’. So, when it comes to OpenShift support, you get what you pay for. In addition to enabling developers to create their own containers, OpenShift provides an online container catalog with contributions from Red Hat and third parties. According to Red Hat, the key to OpenShift lies in the combination of Docker containers and Kubernetes orchestration, both built on RHEL.
Whether it is virtualized or bare metal, a cluster will have multiple virtual machines within it. In Kubernetes, the addition of virtual machines takes a lot of time. Red Hat OpenShift offers a user-friendly dashboard to manage the cluster. The web console of OpenShift provides capabilities to perform some advanced operations on the cluster for better management.
The Quick Architecture of Kubernetes
Readers also need to have some understanding of system administration, infrastructure, and network protocol communication. OpenShift’s implementation of Deployment, called DeploymentConfig is logic-based in comparison to Kubernetes’ controller-based Deployment objects. As of v4.5, OpenShift is steering more towards Deployments by changing the default behavior of its CLI. Many organizations struggle to manage their vast collection of AWS accounts, but Control Tower can help.
Red Hat’s OpenShift addresses this in a much easier way. You can use the provided Ansible playbooks and installers to bring new virtual machines into the cluster easily. It is powered by what is called an Origin Kubernetes Distribution . OpenShift is fundamentally built on Kubernetes, Docker, and some other open-source DevOps toolings like Istio.
What is OKD?¶
That’s another use case where, when it comes to documentation, there is a little gap. As I said, we rarely contact Red Hat support because we use GitOps practices. For High Availability, we always have at least two clusters in two different data centers and in case we cannot fix the cluster itself within 30 minutes we recreate it from scratch.
The worker Nodes can be running other variants of Linux or even Windows. Streamline workflows to get to production faster, including built-in Jenkins pipelines and our source-to-image technology to go straight from application code to container. Containers can be challenging to monitor because they’re always changing. As organizations shift from monolithic infrastructures to microservices, the number of containers supporting these microservices can explode over time to hundreds and thousands of nodes. The latest version of OpenShift also makes for a smarter Kubernetes platform by streamlining the installation and upgrade experience. From start to finish, developers can now be up and running on a Kubernetes cluster in 15 minutes — including full tooling of metering and monitoring.

OpenShift has a much smaller support community that is limited primarily to Red Hat developers. 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. Red Hat OpenShift Online is Red Hat’s public cloud application development and hosting service which runs on AWS and IBM Cloud. ImageStreams and Templates are unique to OpenShift and simplify application deployment and management.
After developers push code to OpenShift either through software version control or continuous integration/continuous delivery systems, OpenShift orchestrates how and when the apps run. It also enables dev teams to fix, fine-tune and scale those https://globalcloudteam.com/ apps as quickly as needed. By using Docker as its model, OpenShift enables any app created with it to run anywhere that Docker containers are supported. This can include on premises, public clouds, private clouds and hybrid cloud environments.

When I approached that scenario, I was thinking in terms of UPI, which stands for user-provided infrastructure in a non-homogenous, domestic cloud environment, a tiny simulated cloud environment. We didn’t consider building our own container platform because Kubernetes is an excellent platform, and OpenShift is built on top of it. We’re satisfied with what we have and see no need to start from the beginning. The pricing and licensing are handled on an upper management level, and I’m not involved in that, but I understand the solution to be somewhat pricey. In the case of a single service, the deployment takes two to three minutes if the Docker image is ready beforehand.
