Working with containers has been a normal part of software development and other areas in IT for quite some time. Various providers have entered the market with their own orchestration tools. Two of the best-known are Kubernetes and OpenShift. Although both solutions offer extensive container platforms, they differ in a number of aspects. Developers should think carefully about which product best suits their needs.
Managed Kubernetes from IONOS
The easy way to manage container workloads. Fully automated Kubernetes cluster setups and maximum visibility and control of K8s clusters.
Persistent Storage24/7 expert supportAutomated cluster setupKubernetes (also known as K8s) is probably the best-known container orchestration tool available right now. That’s partly because of the strong support the project has gained among Google employees. Moreover, Kubernetes offers substantial functional scope and can be adapted to almost any project. This is because the software is open source; a wide range of distributions can be found online. The large community behind Kubernetes is also very proficient. In case of questions or issues, it’s usually relatively easy to find someone who can help.
However, the flexibility of Kubernetes means there is no out-of-the-box solution. In many instances, it’s necessary to adjust many of its settings for container management to work. But this also allows Kubernetes to be used with any operating system.
Are you interested in Kubernetes and would like to use the orchestration tool for your project? Managed Kubernetes by IONOS lets you enjoy the benefits of the software without having to deal with implementation or maintenance.
Much like Kubernetes, OpenShift is available in countless implementations. Red Hat, the maker behind OpenShift, provides various products. That’s one important difference to Kubernetes: OpenShift is a paid product. However, that means once purchased, you can expect professional support. While you need to rely on the voluntary help of experts from the community with Kubernetes, Red Hat offers guaranteed support.
Being a finished product, OpenShift not only offers ease of use but also a great degree of security. Since the system is self-contained and configured by the experts at Red Hat, you can count on high-security standards. By contrast, when you configure Kubernetes, you’re responsible for installing your own security measures.
Nonetheless, Red Hat also provides a free, open-source solution called OpenShift Origin. Its products are available as a Platform-as-a-Service. The packages offered by Red Hat may differ in detail, but they generally concern hosted versions. In other words, the company provides the necessary hardware and software configuration. You can then access a secure test environment with container technology via the internet. Running your own server is not necessary.
What all its products have in common is that they expand on Kubernetes. With OpenShift, you, therefore, get a Kubernetes distribution with additional service. So, instead of having to configure K8s yourself, OpenShift is a finished environment that can immediately be used for development, testing and deployment.
Since OpenShift is based on Kubernetes, the two tools have much in common. But the solutions do vary in certain aspects.
| OpenShift | Kubernetes | |
|---|---|---|
| Operating system | Linux, Fedora, CentOS | Any operating system |
| Security | High-security routine | Security dependent on the user |
| Release cycle | Approximately 3 per year | 4 per year |
| CI/CD | Integral part of the software | Possible via Jenkins |
| User-friendliness | Designed for ease of use | Less intuitive |
| User interface | Easy user interface | Dashboard can be installed |
| Scaling | OpenShift is aimed at the enterprise level, but can be scaled | Kubernetes can be used for any project size |
| Templates | Less user-friendly | High flexibility via Kubernetes Helm |
| Networking | Open vSwitch provides networking possibilities | Plug-ins from third-party providers create networking opportunities |
IONOS Cloud Compute Engine
Medium-sized and large companies choose the cloud from Germany. IaaS and PaaS are services for champions.
SecureReliableFlexibleTechnically, both options are equally good. Although they differ in the details, they are certainly comparable. To make a decision, you should ask yourself whether you want to pay for the convenience of OpenShift or enjoy the maximum flexibility of Kubernetes. The latter will involve investing a lot of time (and possibly resources) in setting up the software.
If you tend to rely on the help from manufacturers, OpenShift may be more advisable. With OpenShift, everything is already configured and you can also utilize the professional support of Red Hat. However, the Kubernetes community is not to be disparaged: you’ll find plenty of experts across the online community who can help with any problem.
If you’re happy with Docker and are already using the container visualizer, you might have thought about trying Kubernetes. But are these two systems actually rivals? Is it a case of Kubernetes vs. Docker? On the contrary, both work really well together. But the container pioneer now also offers its own tool for orchestration with Docker Swarm. So, which is better?
Docker and Kubernetes are well-known technologies that are used for container-based virtualization. With CRI-O there is now a bridge between the Container Runtime Interface (CRI) and the existing runtime environments and container images of the Open Container Initiative (OCI). Find out how CRI-O works in this article.
Kubernetes is the market leader for distributed cluster orchestrators. Interestingly, a number of alternatives exist to give Kubernetes a run for its money. These cover a wide range of possible uses. From local clusters for your own development environment to distributed systems with tens of thousands of nodes. We’ll look at Kubernetes and its alternatives here.
You are certainly familiar with the Kubernetes software. The open source container and cluster manager has established itself as a standard. However, if you want to build your own cluster infrastructure, it makes sense to turn to a more powerful tool that is also easier to use. This is where Red Hat’s OpenShift shows its strength. We explain what makes the software so popular.
OpenShift vs. OpenStack: even though their names sound similar, the two are very different. While OpenStack is used to create virtualized cloud infrastructures based on distributed hardware, OpenShift is all about application containers. Read more about the similarities and differences between these tools and how you can successfully combine them.
