OpenShift is Red Hat's Cloud Computing Platform as a Service (PaaS) offering. OpenShift is an application platform in the cloud where application developers and teams can build, test, deploy, and run their applications.
From what I remember of Pivotal Cloud Foundry/Tanzu, OpenShift has a lot more features. Ultimately, our team went with OpenShift. After trialing multiple providers, we decided OpenShift was the best experience. We also had more confidence in Red Hat.
These were both stood up for separate products. Needless to say the workloads on CDP are going to be migrated to Red Hat OpenShift in the very near future.
Kubernetes is powerful, but managing it yourself takes time. Red Hat OpenShift offers a user-friendly interface, built-in developer tools, and security features, all on top of Kubernetes. It simplifies management and gets you developing faster with all best practices and …
I really recommend the platform because it runs in any kind of environment (cloud, on-prem) and can be migrated between different clouds with no big impact on the company. The possibility of having exactly the same platform across different clouds is a huge potential that puts Openshift ahead of other solutions.
Obviously, it does container orchestration very well because it's the main purpose of the product. Creating routes has been very easy with the product, creating accessible routes, managing quotas, managing our workspace and our workload has been very efficient with this as well as managing our horizontal scalability.
Upgrades can be stressful to watch - often cluster operators report that they are failing even though the upgrade is proceeding without issue.
Native observability is lacking. The canned dashboards are great, but to really dive into an issue, you need to be proficient in PromQL or have a third-party product installed for correlation.
It would be nice to be able to review logs for containers that have been removed, at least for a few hours after they're gone. Instead we have to rely on log aggregators to view historic details.
Leverage OpenShift Online constantly at both the free and paid tiers. While AWS is convenient, it often brings more administration than I want to deal with for a quick application (i.e. Drupal or Wordpress blog). OpenShift also simplifies the DNS registration and ability to share application environments with team members
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
Applications deployed to OpenShift clusters stay responsive when peak load hits or when the traffic dies down - since the platform reacts by scaling out or scaling in the deployed applications elastically - achieved through' policy sense and response automation - leveraging monitoring, measuring (metrics), auto-scaling to meet SLAs, SLOs, and SLIs. This approach works for stateless or stateful business logic hosting applications. The deployed applications perform consistently, stably, and securely across many deployment platforms - public clouds, private data centers, at the edge, or on factory floors - hosted by bare metal or virtual environments.
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.

It's easy to understand what are being billed and what's included in each type of subscription. Same with the support (Std or Premium) you know exactly what to expect when you need to use it. The "core" unit approach on the subscription made really simple to scale and carry the workloads from one site to another.
We never faced any major outage with the OpenShift platform. It's been running fine except for our network timeouts. That's it for this. It's not about, the pods themselves are running fine, but identifying this kind of issue hasn't been easy, but it didn't have any real business impact. It is just about other sre just to better serve our client and improve the platform's reliability.
