Red Hat OpenShift vs. SUSE Rancher vs. Tencent Container

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.

SUSE Rancher as a management tool becomes useful on a larger scale. Small deployments not so much. If someone also requires Kubernetes capacity or storage, Rancher is an excellent choice. Also, without Kubernetes' skills, it is unlikely that Rancher deployment is going to be a success. Then again if someone else is managing your Kubernetes capacity, setting up the software's capacity will yield greater control. Rancher is not a very integrated solution similar to others in the market.

• 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.

• Public and private cloud infrastructure providers based on K8s CAPI
• REST API that can be used to integrate company services with Rancher
• GUI that is easy to learn and use in daily operations
• Builtin GitOps automation solution based on Fleet project
• It is fully open source

• 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.

• No possibility to snapshot Projects. You can snapshot and restore the whole Kubernetes cluster, but not a Project or Namespace. For this, you have to use external tools.
• You cannot detach the Rancher-created Kubernetes clusters from Rancher management.

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

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

Overall it deserves an 8 out of 10. The platform is very easy to use as long as the UI is stable. We have had a few buggy versions in the past. However the CLI is excellent and the platform is simple to manage and maintain. It is easy to deploy and offer for company wide use which increases utilization and ROI.

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.

Incentivized

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.

The documentation is quite complete and there is a very active community that is willing to collaborate and answer questions for those who are just starting out.

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.

SUSE Rancher is an excellent choice for managing multiple Kubernetes clusters, especially when catering to different teams with distinct access rights and requirements. It allows us to deploy these clusters on-premises across various sites or in the cloud. However, if you’re dealing with only one or a few Kubernetes clusters, using SUSE Rancher might introduce unnecessary complexity. This is where EKS wins, as its native cloud based abilities are better suited to scale, support higher complexity and larger demand.

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

• 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.

• Shortens "Time-to-Market" factor for new business applications or implementing new functionalities. From 1 to 50 microservices-based business applications in 6 years.
• 24/7 availability, generates more money. There are many infrastructure components that are regularly powered-off for maintenance or upgrade, bur we rarely are turning off our downstream Kubernetes clusters where our business applications lives.
