Migration success with improved security and integration features
What is our primary use case?
What is most valuable?
OpenShift is a spin-off of Kubernetes, built on top of Kubernetes. It has features that enhance security, ease of deployment, and service exposure compared to Kubernetes. It also provides good integration with GitOps and ArgoCD.
Additionally, OpenShift offers an easy-to-use graphical user interface for cluster management, making it more accessible for administrators.
What needs improvement?
I had to frequently upgrade my cluster due to OpenShift's rolling updates every six months, which I found to be excessive. Making updates a yearly occurrence could be beneficial. In terms of self-service for developers, there is room for improvement. The removal of Grafana and HPA from monitoring caused some issues. Observability could be more robust.
For how long have I used the solution?
I've been working with OpenShift for four years.
What do I think about the stability of the solution?
OpenShift is very stable. I've had my cluster running for over four years, with issues caused more by poor monitoring or user error rather than the product itself.
What do I think about the scalability of the solution?
OpenShift is highly scalable, allowing us to manage thousands of pods effectively. We've implemented features like Horizontal Pod Autoscaling to adapt based on demand and integrated with F5 for high availability.
How are customer service and support?
Red Hat's technical support is responsive and effective. I had 50 to 59 support cases, many of which were resolved quickly depending on the urgency and expertise needed.
How would you rate customer service and support?
Neutral
Which solution did I use previously and why did I switch?
We moved from a legacy system to OpenShift due to its stability and capabilities provided by being backed by Red Hat.
How was the initial setup?
The initial setup was straightforward, especially on the cloud where it was set up quickly. The on-premises setup was more challenging due to additional configurations required.
What about the implementation team?
We handled the implementation internally with our team, which consisted of three engineers managing the analytics environment.
What was our ROI?
Moving to OpenShift resulted in increased system stability and reduced downtime, which contributed to operational efficiency. Although it increased costs, it helped modernize our infrastructure.
What's my experience with pricing, setup cost, and licensing?
The pricing for OpenShift includes support and licensing, which costs approximately $400.
Which other solutions did I evaluate?
We did not evaluate any other options aside from our legacy system before choosing OpenShift.
What other advice do I have?
If you have the skill and experience, Kubernetes can be used in production. OpenShift provides extra coverage in terms of security and management. Have a disaster recovery plan due to frequent updates.
I rate OpenShift at nine out of ten.
Which deployment model are you using for this solution?
On-premises
Automation boosts load management with promising growth in application modernization
What is our primary use case?
The main goal is the modernization of our applications. We have a few applications running on mainframes, which increase costs. We aim to modernize them on containers and microservices. We are shifting towards Kubernetes or Docker. As an enterprise client, the best solution is Red Hat OpenShift paired with support from Red Hat.
What is most valuable?
A valuable feature of Red Hat OpenShift is its ability to handle increased loads by automatically adding nodes. This automation impresses us and benefits us in managing loads on applications.
Although we have just started the transition and are moving slowly, OpenShift has been helpful in modernizing our applications, and it is a positive step forward.
What needs improvement?
The GUI could have more capabilities, particularly around virtualization. Some features are missing, such as storage migrations, when compared with VMware.
As we use both Red Hat virtualization and OpenShift together, differentiating between them becomes challenging. We should aim to include VMware-like capabilities to be competitive, especially considering cost factors.
For how long have I used the solution?
I have been working with OpenShift for a year now.
What do I think about the stability of the solution?
Right now, I would rate the stability of OpenShift as eight out of ten. It performs well under load, providing the desired output.
What do I think about the scalability of the solution?
Red Hat OpenShift scales excellently, with a rating of ten out of ten. It allows for scaling as much as needed, which is a significant advantage.
How are customer service and support?
We are currently dealing with both local support and Red Hat support, and they have been amazing.
How would you rate customer service and support?
Positive
Which solution did I use previously and why did I switch?
We were a VMware house for a long time, about ten to 15 years. However, the cost for VMware skyrocketed, making it hard to continue using it.
How was the initial setup?
The initial setup is complex.
What's my experience with pricing, setup cost, and licensing?
The cost is a crucial factor, particularly with licensing. As things evolve, companies increasingly focus on cost-effectiveness.
Which other solutions did I evaluate?
Kubernetes, as an open-source option, is a significant competitor, particularly for those dealing with cost concerns.
What other advice do I have?
I would rate OpenShift nine out of ten overall.
It is suitable for any company, regardless of size. Smaller companies may opt for open-source solutions like Kubernetes. However, OpenShift offers comprehensive support, which is appealing to enterprise clients.

Seamlessly monitor microservices with streamlined DevOps capabilities
What is our primary use case?
We use it for container orchestration. Some customers don't need to go with the coordinated open source as they need a more enterprise solution, so we use OpenShift. We mainly use it to host IBM CloudSec. We are working with CloudSec for integration, CloudSec for automation, and as a prerequisite for them, they need an OpenShift.
How has it helped my organization?
With OpenShift, it gives me the ability and capability to monitor all my microservices and all my containers using its integrated monitoring. Its horizontal pod scaling is more efficient than the one used in Kubernetes.
What is most valuable?
Most benefit from it, however, I work with Kubernetes, and installing Vanilla Kubernetes is easy. That said, it introduces many tools that need to be set up individually. OpenShift comes ready out of the box, with all tools installed and configured. Red Hat certifies and confirms that all the components are compatible with each other.
OpenShift's superior dashboard is a notable strength, especially when compared to Kubernetes. The integrated DevOps capabilities, such as pipelines and the container registry, are extremely beneficial.
Additionally, its capability to monitor microservices and containers with integrated tools like Prometheus is a major advantage. The horizontal pod scaling exceeds the scalability features I found in Kubernetes.
What needs improvement?
OpenShift requires a very expensive and complex infrastructure. If I have a Kubernetes cluster with one master and three workers, to apply the same configuration in OpenShift, I need about three masters, three infra, and three workers.
It uses around double the resources of vanilla Kubernetes. Also, learning OpenShift requires complex infrastructure, needing vCenter integration, more advanced answers, active directory, and more expensive hardware. These demands can deter people from learning OpenShift.
For how long have I used the solution?
I have been working with Red Hat OpenShift for about four years now.
What do I think about the stability of the solution?
OpenShift is stable but comes at the cost of a very expensive infrastructure. It provides better performance yet requires more resources compared to vanilla Kubernetes.
What do I think about the scalability of the solution?
OpenShift's horizontal pod scaling is more effective and efficient than that used in Kubernetes, making it a superior choice for scalability.
How are customer service and support?
We have dealt with many cases with Red Hat support, and while they eventually solve issues, it sometimes takes them a long time to reach a resolution, particularly with complex matters related to IBM Cloud. We have rated their support a seven out of ten.
How would you rate customer service and support?
Neutral
Which solution did I use previously and why did I switch?
I have used Vanilla Kubernetes, VMware Kubernetes, etc., before. OpenShift is the more powerful and supported solution between them.
How was the initial setup?
The setup involves creating a configuration file called 'install-config.' After providing necessary parameters such as vCenter's URL, username, and password, an Ignition file is generated. A virtual machine is then created from an OVA file with attached parameters.
Although the process is still somewhat complex due to user-provisioned infrastructure, OpenShift offers a simpler installer-provided infrastructure. We chose user-provided because it offers more control over our environment.
What was our ROI?
With OpenShift combined with IBM Cloud App integration, I can spin an integration server in a second as compared to traditional methods, which could take days or weeks.
What's my experience with pricing, setup cost, and licensing?
The cost of OpenShift is very high, particularly with the OpenShift Plus package, which includes many products and services. While I know it's expensive, I do not have the specific numbers.
Which other solutions did I evaluate?
I have used Vanilla Kubernetes, VMware Kubernetes, etc., before. OpenShift has proven to be better.
What other advice do I have?
I recommend having a solid understanding of Kubernetes before transitioning to OpenShift as it is based on Kubernetes. Without this knowledge, managing and maintaining OpenShift can be a nightmare.
I rate OpenShift as a nine point nine out of ten. I suggest considering the necessary infrastructure and related costs before adopting OpenShift.
Which deployment model are you using for this solution?
On-premises
Containerized applications scale efficiently and has flexible pricing
What is our primary use case?
We are building an application that is a containerized application, and we are using Red Hat OpenShift for that application.
What is most valuable?
The concept of containers and scaling on demand is a feature I appreciate the most about Red Hat OpenShift.
Our solutions can easily scale to any number of users or requests if we are running on the cloud. The cloud also supports the pay-as-you-go model, so scalability is the biggest benefit.
What needs improvement?
They could work on the pricing model, making it more flexible and possibly lower.
For how long have I used the solution?
It has been almost one and a half years, maybe a little more.
What do I think about the stability of the solution?
I would rate the stability somewhere around eight to nine out of ten. It is very stable.
What do I think about the scalability of the solution?
It is easy to scale Red Hat OpenShift. The on-demand provisioning of pods and auto-scaling, whether horizontal or vertical, is the best part.
How are customer service and support?
I have been pretty happy in the past with getting support from Red Hat. We haven't had many cases regarding the support for OpenShift, however, we opened a couple of tickets, and they were satisfactorily answered.
How would you rate customer service and support?
Neutral
Which solution did I use previously and why did I switch?
We have also used the VMware environment in our setup.
How was the initial setup?
I would say the initial setup is not very complex, but moderately complex, similar to other containerized platforms like Kubernetes. Compared to what we are used to running, such as other virtualization platforms like VMware, it is moderately complex.
What's my experience with pricing, setup cost, and licensing?
Red Hat can improve on the pricing part by making it more flexible and possibly on the lower side.
Which other solutions did I evaluate?
For the very basic features, I can compare it with VMware Tanzu as we are running a basic setup at the moment.
What other advice do I have?
I rate Red Hat OpenShift somewhere around eight out of ten.
