OpenShift vs. Ku­ber­netes

When comparing OpenShift vs. Ku­ber­netes, it’s clear that Ku­ber­netes serves as a flexible open-source platform for container or­ches­tra­tion, while OpenShift builds on it, adding extra security features, in­te­grat­ed developer tools, and a user-friendly interface. This makes Ku­ber­netes ideal for cus­tomized setups, while OpenShift offers a complete, en­ter­prise-ready package.

What is Ku­ber­netes?

Ku­ber­netes (also known as K8s) is probably the most well-known container man­age­ment system currently. This is partly due to the strong support the project has received from Google employees. Ad­di­tion­al­ly, Ku­ber­netes offers a wide range of features and can be adapted to almost any project. This is because the software is open source, which is why you can find many different dis­tri­b­u­tions online. The Ku­ber­netes community is both large and ex­pe­ri­enced, so if problems or questions arise, you can usually find help quickly.

The flex­i­bil­i­ty of Ku­ber­netes also means that there is no out-of-the-box solution. In many cases, you need to configure a lot yourself to ensure container man­age­ment works. However, this also allows Ku­ber­netes to be used on any operating system.

What is OpenShift?

Just as Ku­ber­netes comes in many dis­tri­b­u­tions, OpenShift is also available in several versions. The key dif­fer­ence is that OpenShift is a paid product from Red Hat, which means it includes pro­fes­sion­al support. With Ku­ber­netes, you rely on community expertise, while OpenShift users benefit from Red Hat’s guar­an­teed as­sis­tance.

The delivery as a finished product brings not only con­ve­nience but also a high level of security. Since the system is self-contained and con­fig­ured by the experts at Red Hat, you can expect high security standards. In contrast, if you configure Ku­ber­netes yourself, you are re­spon­si­ble for all security mech­a­nisms.

With OKD (formerly OpenShift Origin), Red Hat also provides a free open-source option. The other offerings are available as Platform-as-a-Service. While the specific packages differ in detail, they are es­sen­tial­ly hosted solutions: Red Hat supplies the hardware and software con­fig­u­ra­tion, and you access a secure en­vi­ron­ment for container tech­nol­o­gy directly over the internet—no own server required.

All products have in common that they are built on Ku­ber­netes. With OpenShift, you choose a Ku­ber­netes dis­tri­b­u­tion with ad­di­tion­al service. Instead of con­fig­ur­ing K8s yourself, you rent a ready-to-use en­vi­ron­ment with OpenShift, which can be im­me­di­ate­ly used for de­vel­op­ment, testing, and de­ploy­ment.

OpenShift vs. Ku­ber­netes com­par­i­son

Since OpenShift is based on Ku­ber­netes, there are some sim­i­lar­i­ties between the two tools. However, there are dif­fer­ences in certain aspects.

Which solution should you choose?

From a technical per­spec­tive, both solutions are on par, with only certain details setting them apart. The real decision is whether you prefer to pay for the con­ve­nience of OpenShift or take on the flex­i­bil­i­ty of Ku­ber­netes, which comes with a greater time in­vest­ment for setup.

If you depend on reliable support, OpenShift is the safer choice: every­thing is pre­con­fig­ured, and Red Hat provides pro­fes­sion­al as­sis­tance. Still, the Ku­ber­netes community should not be un­der­es­ti­mat­ed—its large network of experts can also provide valuable help when needed.
