Red Hat OpenShift vs. Oracle VirtualBox

Red Hat OpenShift, despite its complexity and overhead, remains the most complete and enterprise-ready Kubernetes platform available. It excels in research projects like ours, where we need robust CI/CD, GPU scheduling, and tight integration with tools like Jupyter, OpenDataHub, and Quiskit. Its security, scalability, and operator ecosystem make it ideal for experimental and production-grade AI workloads. However, for simpler general hosting tasks—such as serving static websites or lightweight backend services—we find traditional VMs, Docker, or LXD more practical and resource-efficient. Red Hat OpenShift shines in complex, container-native workflows, but can be overkill for basic infrastructure needs.

It is best suited when you want to have different operating systems on your laptop or desktop. You can easily switch between operating systems without the need to uninstall one. In another scenario, if you expect some application to damage your device, it would be best to run the application on the VM such that the damage can only be done to the virtual machine. It is less appropriate when time synchronization is very important. At times the VMs run their own times differently from the host time and this may cause some losses if what you doing is critical. Another important thing to take note of is the licensing of the application you want to run your VM. Some licenses do not allow the applications to be run on virtual servers so it is not appropriate to use the VM at this time.

• One of the big advantages of Red Hat OpenShift is, especially over Kubernetes itself, is that it provides a lot of built-in operators for doing a lot of different things right out of the box that you don't have to worry about trying to configure. So one of the big ones is, I mean, right in your face is that user interface and being able to work with it inside of a browser. And I think that works very, very well.

• Can spin up multiple VMs on a host-only network that speak to each other and allow for interesting test environments spun up at will.
• Cross-platform functionality allows me to run it on my Linux Desktop and know that tutorials I make with it could be approached by someone on a Windows or Mac OSX system. Hyper-V is limited to Windows, and VMware Workstation requires a license (VMware Player is free, but is not open-source and is more limited in comparison to VirtualBox).
• If you are testing tools like Vagrant and Test-Kitchen, VirtualBox often seems to have the highest amount of support and documentation when it comes to compatibility (though, many people do use Hyper-V or VMware Workstation without issues).

• I would say that's the logging part because Red Hat OpenShift write tons of locks and if most time in the finance industry, we cannot use the built in logging infrastructure for compliance reasons. And we have to forward the logs out of the system and this is, it's too much, which we forward from one cluster. Most time we'll build up multi clusters, so we speak about 10 or more clusters. And if you send log files from 10 or more clusters, the logging systems are not prepared to take that much load. And then really often you have license problems with the logging system, so that's not really, really fun. So logging could be improved.

• The memory footprint is high, and requires above 8 GB of memory to run an Ubuntu VM smoothly (considering developing inside ubuntu OS inside a MacBook Pro).
• Some known issues with OVF/OVA images import/export. We had the issue of some sections in OVF being ignored (especially Startup and Install sections).
• Some intermittent issues when mounting external hard drives and trying to access them from within the running VM.

Going to stay with this platform for the unforeseeable future. It matches our Target Architecture 2030 strategy internally to adopt more modularized platforms with Open Source on the back-end so that if needed containerized workloads can move to a different platform. With open-source based application telemetry collection being utilized on the back-end, integrating our already existing oTeL observability based platform makes it easier for our apps to be monitored

I give this rating because virtual box is inexpensive but there is another product such as vm ware that can also be used

As I said before, the obserability is one of the weakest point of OpenShift and that has a lot to do with usability. The Kibana console is not fully integrated with OpenShift console and you have to switch from tab to tab to use it. Same with Prometheus, Jaeger and Grafan, it's a "simple" integration but if you want to do complex queries or dashboards you have to go to the specific console

I love using the Graphical User Interface. The VirtualBox Manager is very easy to understand and use. You can quickly create, configure and manage all your virtual machines in one window. It makes operating virtual machines easy and simple. When using VBoxManage it gives the user comprehensive control over VirtualBox so that you can use automation and scripting at the command-line interface

Redhat openshift is generally reliable and available platform, it ensures high availability for most the situations. in fact the product where we put openshift in a box, we ensure that the availability is also happening at node and network level and also at storage level, so some of the factors that are outside of Openshift realm are also working in HA manner.

Dependency on the Host OS means it is as reliable as it is possible to be. Application errors are beyond the purview of the application.

Overall, this platform is beneficial. The only downsides we have encountered have been with pods that occasionally hang. This results in resources being dedicated to dead or zombie pods. Over time, these wasted resources occasionally cause us issues, and we have had difficulty monitoring these pods. However, this issue does not overshadow the benefits we get from Openshift.

No issues, especially with the extensions addons.

Their customer support team is good and quick to respond. On a couple of occassions, they have helped us in solving some issues which we were finding a tad difficult to comprehend. On a rare occasion, the response was a bit slow but maybe it was because of the festival season. Overall a good experience on this front.

Oracle have a very fast response rate and a strong user community. One can geet help from many sources if they choose to research for themselves.

I was not involved in the in person training, so i
can not answer this question, but the team in my org worked directly
with Openshift and able to get the in person training done easily, i did not
hear problem or complain in this space, so i hope things happen
seamlessly without any issue.

We went thru the training material on RH webesite, i think its very descriptive and the handson lab sesssions are very useful. It would be good to create more short duration videos covering one single aspect of openshift, this wll keep the interest and also it breaks down the complexity to reasonable chunks.

We really enjoy using virtual box. We do not require to buy expensive hardware but instead we can minimize costs and maximize profits.

We utilized the Thycotic Secret Service to manage all our application secrets, resulting in seamless integration with our applications. We developed all the applications using Red Hat Fuse (currently migrated to Quarkus). We used the built-in Kali Linux support of OpenShift to manage and configure the services and API. Additionally, the Red Hat Developer Studio facilitates faster development.

VirutalBox is very similar to using Vmware with the slight difference in appearance and what might be considered a less polished look. However, what it lacks in polish and looks it makes up for in functionality, easy of use and the wide range of operating systems and features it supports without the need of buying the full professional edition

This is a great platform to deployment container applications designed for multiple use cases. Its reasonably scalable platform, that can host multiple instances of applications, which can seamlessly handle the node and pod failure, if they are configured properly. There should be some scalability best practices guide would be very useful

Incentivized

The only problem I have found is that the deployment is dependent and intrinsically linked to the Host OS. This is different from bare metal solutions which remove that dependency on a Host OS. The latter is more reliable and removes a layer of potential failure.

• When you talk about ROIs, I don't have any negative impacts I wanted to call out here. There is no negative impacts. In fact, it's all positive impacts what we set as our milestones towards achieving our goals, towards achieving our greater vision. Red Hat OpenShift has got a big role in it and it is certainly helping us.

• Direct cost savings - it enables me to do the work I need to do without purchasing additional physical computers
• Time savings - it allows me to perform testing and reversion that would take much longer on a physical computer
• Increased productivity - it enables me to more easily integrate with customer environments
