Red Hat OpenShift vs. VMware vCenter

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.

VMware vCenter Server is suited for pretty much any environment using virtual servers. It allows a centralized management view of the virtual servers and the physical servers that the virtual servers run on. There are so many things that VMware vCenter Server can do, including large Enterprise options that are cost-prohibitive for most organizations.

• One thing is the way how it works with the GitHubs model on an enterprise business, how the hub and spoke topology works. Hub cluster topology works the way how there is a governance model to enforce policies. The R back models, the Red Hat OpenShift virtualization that supports the cube board and developer workspace is one big feature within. So yes, these are all some features I would call out.

• First and foremost, it provides a platform for us to virtualize our servers and it does it very well. Having the ability to spin up a new server from a template in a matter of seconds is amazing and saves precious time and resources.
• VMware vCenter Server also provides the ability to view performance & statistical data that assists my team in balancing our host environment. Leveraging the vMotion functionality, we can quickly move VMs from one host to another for maintenance purposes, etc...
• VMware vCenter Server also make it easy to add / modify hardware configurations within the VMs setup. Adding RAM, hard drive space, processor cores, etc...is as easy as it gets.
• VMware vCenter Server makes it easy to backup and restore a VM from the console. You can quickly create a backup of any VM and store it during upgrades, etc...for easy roll backs.

• So I don't know that this is a specific disadvantage for Red Hat OpenShift. It's a challenge for anything that Kubernetes face is. There's an extremely large learning curve associated with it and once you get to the point where you're comfortable with it, it's really not bad. But beating that learning curve is a challenge. I've done a couple presentations on our implementation of Red Hat OpenShift at various conferences and one of the slides I always have in there is a tweet from years ago that said, "I tried to teach somebody Kubernetes once. Now neither of us knows what it is."

• I still am not happy with the web interface. While convenient in that I can access vCenter from anywhere I have a browser connection, It feels slower than the thick client and if I'm doing anything that takes longer than a few minutes, I'll always opt for the thick client.

This is the current strategy for the company, most of the products in the organisation are aligning to Openshift and various use cases it support. Also lot of applications are being developed for AI use case, openshift.AI provides opportunity to host and leverage the AI capabilities for these applications

We are very dependent on this software, it has become a much needed tool to perform the daily tasks that are required to maintain the virtual server environment. VMware has become very pricey over the years, so we are looking for alternatives for cost savings strategy, but nothing has been found to be on par to what we are currently using

The virtualization part takes some getting used to it you are coming from a more traditional hypervisor. Customization options are not intuitive to these users. The process should be more clear. Perhaps a guide to Openshift Virtualization for users of RHV, VMware, etc. would ease this transition into the new platform

I work with vCenter for 10+ years and i love it. I can find my way around and can help building and expanding the platform. It is easy to use and there are a lot good communities for the extra support when needed. Even the Homelab community is of great value.

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.

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.

Every time we need to get support all the Red Hat team move forward looking to solve the problem. Sometimes this was not easy and requires the scalation to product team, and we always get a response. Most of the minor issues were solved with the information from access.redhat.com

VMware support has always been fantastic and they have been invaluable in solving tougher issues that have been run into. Most of the time, any oddities encountered are fixed by available updates. This can be deduced by support quickly with logs within vCenter. We have not run into something yet that support was unable to help with. They either have a solution already, or they are able to find one quickly.

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.

The learning curve is quite high but worth it.

Since moving away from the Windows Server hosting the vCenter application and instead using a virtual appliance, it has become much easier to implement and deploy the new versions. We can easily create a snapshot or clone of the vCenter vApp to ensure any problems encountered during the upgrade can be mitigated with a fall back to the old version to prevent unscheduled downtime.

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.

vCenter is much more complete as a solution than other products that I have looked at and it works very well for our environment. vCenter is very easy to configure and does not have the unnecessary steps to set up and configure. Also, the different storage vendor support makes it easy to configure and maintain without having to use separate applications or consoles.

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

• It has allowed us to see where we need to be in the container world. I'm going to call it a net neutral impact, not negative or positive. It has given us a sense of what we are ready for and what we're not ready for. You know where you stand.
• You don't know what you don't know, so it helps us know what we want to know.

• Significantly reduced the number of standalone control system servers on site
• Allowed scaling up of existing systems and migrating other systems onto new infrastructure without additional hardware outlay
• The initial licensing and hardware purchase cost was high, however will pay off by the reduction in hardware costs required for planned systems
