Red Hat OpenShift Container Platform Reviews

For the majority of use cases, we're actually building APIs for both the enterprise API and also OpenAPI. It's mainly for integrations for the backend. We implement the system for the customer.

It's deployed on a private cloud and on-prem. We are using version 5.8.

The banking transactions, inquiries, and account opening have been the most valuable.

The monitoring and logging could be improved. I think it would help developers in terms of provisioning the database and the whole development lifecycle.

I have been using this solution for two years.

Technical support is standard.

Initial setup was fine. If it's set up on-premise, it takes longer, maybe about four or five days. We actually deployed it on the cloud once using IBM. That takes a shorter amount of time because it's a managed service.

We used a consultant. 

I would rate this solution 8 out of 10.

If you care about your performance and the support, I would recommend it for enterprise mission critical applications.

As an IT service provider, we work on enterprise technologies for our customers.

We have multiple customers with multiple domains, but the majority of our experience is in the banking and telecom sectors. In banking, they're using the OpenShift platform for their microservices-based requirements, and similarly on the telecom side, they are using it for the microservices-led solutions.

We started with the on-prem deployment of OpenShift Container Platform, version 3.2. But currently, we are also helping our customers to migrate to 4.x and to cloud solutions. The plan is to move to a cloud version, strictly on AWS. We are exploring the OpenShift Container Platform cluster, and ROSA (Red Hat OpenShift Service on AWS) the latest one with the managed services. By mid-2022, we'll probably be on cloud with this.

OpenShift eliminates distractions so that we can focus on innovation and other things. It completely removes overhead for the developers in terms of managing the orchestration of Kubernetes container clusters. It provides all the built-in features for managing these requirements. As a result, our team is more focused on development and on innovations in the underlying services. With microservices or applications that are deployed on OpenShift, they are able to focus more with the business requirements and innovate by further optimizing efficiently, utilizing the resources at a Kubernetes level.

Some of the primary features we leverage in the platform have to do with how we manage the cluster configurations, the properties, and the auto-scalability. These are the features that definitely provide value in terms of reducing overhead for the developers.

Also the Kubernetes cluster management or orchestration is provisioned through the UI and the CLI.

We are using the Red Hat OpenStack OpenShift Platform. It is much faster in terms of deploying the cluster. As of now, our experience rolling it out is more on the on-prem, but I think with the 4.0 version there is a little bit of a change regarding the way it is deployed, either using the installer base or user-driven installations. It takes a couple of days just to roll out the entire cluster and configure it so that it is ready for the applications or the services to be deployed on the cluster.

The robustness, the availability in terms of resilience, and the service availability with the multiple cluster nodes configured automatically, is pretty good. Even if load balancing is required across multiple clusters with the SDN network, it's pretty good. We haven't had many issues when it comes to robustness. We are happy with the performance provided.

From our experience on the on-prem, we know that there are 10 layers of security provisioned by the OpenShift platform, starting from the kernel level, and including the clusters and the container level. That definitely helped us to achieve a lot of enterprise security requirements in terms of accessibility and managing the infra part or the cluster part.

For running business-critical applications, the solution's security is pretty good. We are able to achieve consistent efficiency and availability for all our critical service requirements, when spanned across multiple DCs with the load balancer and DR solutions. We don't have to spend much on it, once we orchestrate the cluster with the proper configurations. At that point, everything is taken care of automatically.

At the service level, I don't see a very granular level of security as compared with the container-based clusters. It is at the Kubernetes level, not at the service level.

Also, when I compare it with the other container or Kubernetes technologies, we have pretty good documentation from OpenShift, but with the recent trend of cloud-native, fully managed serverless services, I don't see much documentation about how a customer should move from on-prem to the cloud, or what is the best way to do a lift-and-shift. Even if you are on AWS OCP, which is self-managed infra services, and you want to use the ROSA managed services, what is the best way to achieve that migration? I don't see documentation for these kinds of use cases from Red Hat. There is some room for improvement there.

We have been using OpenShift Container Platform, as an organization, for the last three or four years.

The stability is pretty good. The industry has been using these enterprise solutions over the long term and we haven't heard of or seen any issues with stability. Of course, it depends on the way you configure it or manage it. But given best practices, the stability is pretty good.

The solution gives us the flexibility to start with a small number of nodes and to scale it to the maximum number of nodes. As of now, we haven't gone beyond whatever the limitations are, in terms of the number of clusters or nodes, within OpenShift. We are well within the limits and are able to achieve our requirements. That aspect makes it more flexible.

Scalability is definitely one of the positives with OpenShift, where you can have a distributed cluster across multiple DCs or multiple Availability Zones with AWS. The only thing we don't see is much documentation. If we want to maintain Active-Active disaster recovery or hot and warm availability requirements, even in on-prem, how do our clusters scale across different regions or different availabilities? And how do I manage the internal cluster storage being replicated across multiple clusters? How does that work, and how do we prove it? That's another use case where, when it comes to documentation, there is a little gap.

But overall, scalability is pretty consistent and achievable with OpenShift.

I'm not involved much in post-production support. Usually, it is the customer team that gets into those kinds of requirements. But what I heard from our customers is pretty good, in terms of the support provided by the Red Hat. We know that they have a very good enterprise support team and provide support fairly quickly for technical issues.

On AWS, we have seen they have OCP-dedicated infra, which is completely managed by Red Hat. Now with ROSA, where AWS and Red Hat are both managing it, we are expecting a similar kind of support from Red Hat.

Whether Red Hat acts as a partner with our customers depends on the customer. Most of our customers use Red Hat enterprise support for technical issues with OpenShift Cluster Platform. But they don't get deeply integrated with Red Hat in terms of exchanging ideas or innovating new solutions. But Red Hat is always providing its innovations and doing research into new products. That has definitely helped our customers.

We embarked on OpenShift as our first enterprise container technology.

There are open-source-based Kubernetes services provided by AWS and there are a number of cluster-based solutions available. But what Red Hat and OpenShift did was that they packaged all of their solutions within their platform so that it provides added features. For our finance or banking customers, adopting an open-source solution is challenging, but the enterprise-grade support from Red Hat makes it much easier for them to adopt the OpenShift cluster.

As for building our own container platform, initially we tried with Dockers, but when we compared other Kubernetes cluster technologies to OpenShift we found that OpenShift is a much better solution in terms of the features.

With the on-prem solution, with OCP, where you have control of your infra, I feel the setup is straightforward, because you know OpenShift 4.0, or other versions, and how to install it. You have the resources and the skill sets and it is easy to just start with that part.

But ROSA is a very new approach, with the fully-managed and serverless cluster. I feel there are some gaps there because you don't have control of infra provisioning. AWS and Red Hat directly provision things once you provide the configurations. But if a customer wants to use a fully managed service with some level of customization, we don't see how we can easily achieve that.

On average, if it's a single-cluster deployment for five nodes, it may take three days to get the infra up and running. And then, to do all the configurations and get the applications deployed, it probably takes another one or two days, including the testing and readiness of the infra. So a total of about five days is the optimum timeline to get a single cluster up and running with the services deployed in it.

As we are exploring the cloud migration side of things, we definitely have a deployment plan where we use the templates, including Terraform templates, when it comes to infra and core provisioning. We then have a clusterized deployment as a basic migration approach or a phased approach. We leverage tools like the Migration Toolkit from Red Hat itself and some AWS tools which are relevant if there are challenges with agent installation and the like.

We have seen return on investment from using OpenShift. The TCO is much better, comparatively, over the course of three to five years. We have seen a reduction in infra and cluster management operational costs. These are some of the aspects where we have definitely seen a return on investment.

OpenShift with Red Hat support is pretty costly. We have done a comparison between AWS EKS (Elastic Kubernetes Services) which provides fully managed services from AWS. It's built on open-source-based Kubernetes clusters and it is much cheaper compared to Red Hat, but it is a little expensive compared to ECS provided by AWS.

Initially, we had this interim state where we wanted to move as a lift-and-shift, meaning we wanted to move OpenShift to OpenShift. We had three choices: OpenShift Container Platform, the OpenShift dedicated platform from Red Hat itself, and ROSA with the fully managed services. For lift-and-shift, we wanted to maintain an as-is state and made a decision to go with AWS OCP, which helps us to control our infrastructure and deployment requirements, while maintaining the as-is state. Price-wise, this option is less than ROSA. In ROSA, we would need to pay the cost for the underlying AWS resources we would be using, plus a nominal cost to Red Hat for managing every cluster and every worker node.

There is no doubt about things, feature-wise. In terms of scalability, availability, stability, robustness, OpenShift stands out. It's the cost and support factors which make the decision a little difficult.

If a customer is looking for a fully controlled or fully managed container technology, OpenShift is definitely a choice for them. But there are other services available, like AWS EKS, which come with similar kinds of services. It depends on if you need a deep-dive solution: Do you want to maintain your own infra or do you want fully managed services? And do you want to leverage other OpenShift cluster services? But OpenShift is the choice.

We don't use the full-fledged automated services for OpenShift clusters as of now, although we do use a few of the automated services. What we are using currently is sufficient and it helps us to meet a lot of audit and telemetric requirements.

In terms of using it for cloud native stacks and meeting regulatory constraints, we are still exploring that. We are currently looking at the AWS OCP and ROSA platforms. ROSA provides flexibility in terms of installations and managing the entire infra. ROSA is completely managed by automated serverless services, where you just provide the initial configurations for the kind of a cluster you need and it automatically provisions the infrastructure for you. Whereas with OCP you have control over the infrastructure and you can play with your cluster orchestrations, configurations, et cetera. In these ways, with the cloud services, we do have flexibility, but the cost factor may be a differentiator in terms of the on-prem and the cloud versions.

We definitely plan to use the CodeReady Workspaces, but we are not there yet. The idea is to move on to the AWS Workspaces.

Overall, I would rate the solution at nine out of 10. It has everything. For me, it is not a 10 because the support and the pricing costs stand out.

The solution being used for application containization.

I like the Flexibility of the solution. 

Metrics monitoring feature needs improvement.

I have been using Red Hat OpenShift Container Platform for five years.

Overall, I rate the solution a nine out of ten.

Our primary use case for Red Hat OpenShift is to deploy applications. We utilize the platform to manage multiple pods and ensure seamless scaling of our nodes and servers to meet the demands of our high-availability applications.

The platform has significantly improved our organization by enhancing productivity and reducing the time required to deploy applications. It allows for faster deployment and continuous delivery, which has streamlined our development processes.

The most valuable features of Red Hat OpenShift include its integration with Kubernetes and the user interface, which enhances the end-user experience and accelerates the deployment process. These features contribute to increased productivity and efficiency for our developers.

The product could benefit from additional operators and tools integrated with OpenShift. Furthermore, enhancements to the user interface and including more features would be beneficial.

I rate the platform's stability a seven out of ten.

The platform is scalable. 

I have opened some tickets but did not receive the required technical support.

Neutral

The initial setup was complex. I rate the process a two out of ten.

The implementation was done in-house.

I rate the product an eight out of ten. 

The platform's most valuable features include cost reduction through VM application migration to containers, scalability for controlling memory and CPU usage, and the reliability offered by application containerization.

One area for product improvement is the support limitations within the subscription models, particularly the restricted support hours for lower-tier subscriptions.

I have six years of experience working with the OpenShift Container Platform.

The product has proven to be very stable, crucial for supporting our applications effectively.

Setting up the OpenShift Container Platform was straightforward. It's primarily deployed on-premises, although I've also utilized cloud solutions. It takes 15 days to complete the setup. Around three executives are involved in both the deployment and ongoing maintenance. 

I rate the process an eight. 

The migration from VMs to containers has resulted in significant cost savings for us.

The product pricing is competitive and structured around vCPU subscriptions, aligning with our application requirements.

OpenShift integrates seamlessly with our CI/CD pipelines, offering robust automation and deployment capabilities. I would highly recommend it.

I rate it a ten.

We use OpenShift Container Platform for load balancing, scaling, self-healing, and distributed key database features. It helps us monitor cluster configuration.

The product has a CentOS operating system providing a stable and compatible foundation for hosting Red Hat OpenShift clusters. It helps in creating an architecture framework automatically. It makes it possible to control the CentOS API server and Kubernetes console.

We encounter difficulties while accessing the environment and managing the cluster. This particular area needs improvement.

We have been using OpenShift Container Platform as a partner for seven to eight months.

The product's stability is manageable.

The product is scalable. It is suitable for medium and enterprise businesses.

The technical technical support services need updating with changing times.

Positive

We have used SAP before. We switched to OpenShift Container Platform for better support facilities. We are their gold partner. However, the support services have needed improvement in the last six to seven months.

The initial setup process is easy. We have a dedicated team for data installation. It takes around three months to complete. The product is easy to maintain as well. We have a team of 35 to 40 executives to work on it.

I advise others to learn about the tool, including certification, warning alerts, security, and monitoring features. It isn't easy to manage the cluster using it.

I rate OpenShift Container PlatformOpen an eight out of ten.

It is used for containers.

It is very lightweight and can be deployed very fast, especially when it comes to containers. It can spin the web and the DB very fast, so we don't need to deploy the server and the VM. Everything is in the container.

There is room for improvement with integration.

I have been using the solution for one year.

The solution is stable.

The solution has good scalability. I rate the scalability of the solution a nine out of ten. There is also room for improvement in the scalability of the solution.

One or two users are using OpenShift in our company, and we hope to increase the usage.

The support is very good. Their response and technical skills are good.

I have used Docker before. We shifted to OpenShift because we were using Docker for self-learning.

The initial setup is complex. The solution is deployed on-premises. However, it can also be deployed on the cloud.

To deploy OpenShift, first, you must get the installer and then prepare a minimum requirement. You will need a key physical server as a load balancer. OpenShift has a lot of roles in its nodes, with worker nodes and master nodes. Since different nodes have their role, the setup is complex. You will need to set up ten or 12 nodes like this. After you have set up all the nodes, you need to do the integration and set up OpenShift.

It takes a month or a year to deploy it.

The deployment can be done in-house. There are two people required for maintenance.

The pricing is expensive for licensing. The customer has to pay for the license.

Before choosing OpenShift, I advise you to know your application landscape very well. Only then will you know if you require OpenShift. If you are unclear about your application environment, layout, and structure, it is potentially not a good idea because you don't understand it.

Overall, I would rate the solution a five out of ten.

The product is used to deploy applications. We provide the base image that has the fundamentals for the BPM product. Then, it's in our docker farm and another image is created that extends the base image. The second image adds application-specific requirements on it. Basically, it's layering the application on top of the base image and a new image is created and that is deployed onto OpenShift.

The OpenShift platform is built on the Docker Ecosystem. The image we create is easily portable. OpenShift is built on top of the Docker Ecosystem which is one advantage.

It has run time. It has all the binders required. Once built and once tested that it is working, it'll work wherever it's deployed. 

On OpenShift, it's easy to scale applications. We can easily scale up or scale down.

It's a container platform. It uses resources efficiently - specifically on the CPU RAM limit. We can create as many containers as needed. The underlying resources are utilized well.

It's intuitive and user-friendly. They have a very good UI, through which we can add all the artifacts required for OpenShift. Also, they are providing API through which also we can work on the projects. Apart from that, they also provide the CLI, a command-line interface. In my view, I think it's very good. I don't see anything more that is needed.

Everything is good. I don't see any need or any improvement that can be done. They cover CI/CD and I have not seen something which is missed in this product.

The initial setup can be hard.

It takes some time to learn everything. There's a learning curve. 

I've used the solution for four or five years. 

It's very stable. We've never had any failures. It was always up and running. It's very reliable. 

Our company is quite large. I'm not sure how many people are actually using the solution. We have a small team, and, of us, about four are using it. However, that's not indicative of the company as a whole. 

So far, the scalability is good. 

We're using it regularly, on a daily basis. 

I haven't reached out to support. For this product, we are focused more on the application side. We use the platform, however, our focus is on the application side. Whatever happens, the team that maintains and does the upgrade of the platform, interacts with the vendor. We never interacted with the vendor for OpenShift.

I tried AWS. It's also a cloud product, however, not exactly the same as OpenShift. They offer a different set of services. It's not a past product platform, it is a service product. I have used AWS, which offers cloud services. We cannot really compare both of them.

At the outset, the initial setup was not easy. The learning curve is always there. The lack of materials at that point in time also made learning a little bit hard. However, after some point, we had very good documentation and we could easily handle the product. We could easily start working on it. It's gotten better over time. For the first three or four months, it was hard, however, after that, it was easy.

The first deployment took around four to five months as we had to develop an agent data rate. It took some time. However, the changes, usually, could be done in a week or so. It was not a long time. Every week we can easily make the changes.

There's no maintenance. We don't do it. We use the platform and some other team will automatically do the upgrade. We don't have to do it ourselves. It's done by a separate team.

I'd rate the solution four out of ten in terms of ease of setup.

We handled the implementation ourselves. The solution does not offer any consultants or integrators. We managed everything through the UI.

I cannot speak about the pricing. We never interact with the vendor for that. There is a separate team who takes care of the platform and they work with the vendor for pricing.

While my company has some sort of partnership with eh solution, I am just an end-user.

It's my understanding I'm using the latest version of the solution. 

I'd rate the solution ten out of ten.

I would recommend this product. It's easy to develop applications and it gives you the option to manage your cloud on a private platform. We don't have to rely on public infrastructure. In the private infrastructure, we can have our server and use this product and make the application secure.
