Red Hat OpenShift vs. Proxmox VE vs. Untangle NG Firewall

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.

Proxmox VE is a virtualization platform that provides a range of features and functionalities suitable for various scenarios. Here are some specific scenarios where Proxmox VE is well suited and some scenarios where it might not be the best choice:Well-suited scenarios:Virtualization of server workloads: Proxmox VE is well suited for virtualizing server workloads such as web servers, mail servers, database servers, and other similar applications. Its high-performance virtualization capabilities allow these workloads to run smoothly and efficiently.Hosting multiple virtual machines (VMs): Proxmox VE is ideal for hosting multiple VMs on a single server. It provides efficient resource management, allowing users to easily allocate resources to each VM.Clustered environments: Proxmox VE is a great choice for clustered environments. It supports clustering and can easily manage multiple servers, providing high availability and load balancing for mission-critical applications. Less appropriate scenarios: Limited hardware resources: Proxmox VE requires significant hardware resources to run efficiently. If you have limited hardware resources, it might not be the best choice. Simple applications: If you only need to run a single, simple application, Proxmox VE might be overkill. Other virtualization platforms or even a basic web hosting service might be more appropriate.

Midsized business is where I have used it. Have used it to connect to other Untangle boxes across town and in other countries with NO issues and works with MS Domains across these VPN connections. Probably less appropriate for small home networks or large businesses.

• 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.

• ZFS storage out of the box. The integration with ZFS is fantastic. You can easily create pools to store your VM images and data on, and the Proxmox web UI provides an easy way to check drive health, ZFS scrub status, etc.
• Great web UI. Practically everything configurable is available to do so from the web user interface. You'll rarely need to drop to the command line for administrative tasks, unless you want to, in which case you can do that too. The UI also provides graphs and visualisations to help you keep check of how everything is performing.
• Easy to setup a high availability cluster. Although Proxmox VE works perfectly well on a single server, you can also install it on multiple hosts and setup a cluster.
• Uses a Debian core system with an Ubuntu based kernel. This means everything to do with the base operating system is tried and trusted. We use a lot of Debian and Ubuntu installs, so having this run underneath Proxmox VE was an added bonus for us.

Incentivized

• The firewall is easy to set up and manage.
• The open VPN while not as feature rich as some other options is rock solid and consistently needs nothing
• The web filter app is great, it's easy to block broad categories or specific things as well as white list whatever is needed.
• Support is responsive and accurate.

• 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 web UI does not work as well on mobile devices. It is useable, but a mobile optimised / responsive UI would be nice to have. There is a mobile app, so that may alleviate this issue, but I have not yet tried it.
• Support in the community forums could be better. There are paid support plans, but new users trying out the software will not have access to this. Answers to questions can sometimes be terse, and I can imagine this may put some people off.
• The wiki is a bit hit and miss with certain topics. I've often seen outdated or missing information, and the whole thing looks like it could do with some polish. I'd love to see it opened up for the community to add to.

Incentivized

• The UI could be a little flashier.
• Getting your license file moved from one firewall to another can be tough at times... but support is great if you need it.
• Ability to upload reports to a portal versus getting them emailed would be best (some reports can get 100+ Mb depending on all the bells and whistles).

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

Proxmox VE provides the most capable, yet stable virtualization platform in the market today. Licensing options are also competitive and cost-effective for support, and support is extremely fast and knowledgable of getting issues resolved as quickly and soundly as possible.

Service renewal is in Feb 2021. We will be renewing!

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

The interface is easy to use for most of it, but still lacks screens for some configurations. Also, a few of the screens are not as intuitive as they could be. This is specially true with disk and network configuration, where some graphic/visual representations of the configurations would be very useful

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.

Proxmox VE's ha-cluster functionality is very much improved, though does have a not-very-often occurrence of failure. In a 2-node cluster of Proxmox VE, HA can fail causing an instance that is supposed to migrate between the two nodes stop and fail until manually recovered through the command-line tools provided. Other than this, the HA clustering capability of Proxmox VE has proven to be reliable in 3 or more clustered environments with much less chance of these failures to occur.

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.

Proxmox VE's interfacing is always fast to load, both the Web interface and the command-line tool interfaces. Reporting is practically real time almost all the time, and you can see everything in mere seconds, easily able to identify if something is wrong or it everything is in tip-top shape as always desired

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.

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 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.

Proxmox Virtual Environment is better, less costly, it has better CAPEX and OPEX, is open source and more robust and flexible.

It is an agnostic product, one can use a PC clone or a high end server to install it, and it works flawlessly on both.

The product has a large life cycle, is stable and has few problems and vulnerabilities than the other propietary products.

I could never come close with these two products to the level of functionality and security I have with Untangle. Simply put, there is absolutely no contest. In addition, the cost of these other solutions was many thousands more than the academic cost for Untangle. Many times have I experienced threats and inappropriate content passing through these other products. All of that was stopped the moment I implemented Untangle, even before I started to customize the settings.

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

Proxmox VE provides everything you need to quickly add new storage mediums, network and local, as well as networking interfaces, such as using Linux standard bridges and now Open-vSwitch bridges which can be even more scalable than before. Proxmox VE 4.0 dropped support for OpenVZ in favor of the more well supported and native LXC and made an upgrade path to it very simple.

• 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.

• Due to the open source nature of Proxmox, we have no licensing costs while training our employees
• We've migrated 100% of our clients to Proxmox and have found improved uptime, and flexibility.
• In the 10 years of using Proxmox, we've yet to lose any data or not be notified of backup issues.

• Easy setup and implementation made ROI easy to achieve. An Untangle HA solution is 1/2-1/3 the cost of a comparable Cisco/Checkpoint/Palo Alto solution.
• non-business internet usage has nearly ground to a halt.
• SD-WAN integration made it easy to connect branch offices quickly without complicated IPSEC configuration.
