The monitoring is problematic. The product monitoring tool does not work for us. We had to purchase the Dynatrace solution to monitor our product and our applications, and this is a weakness of OpenShift Container Platform. If there was some orchestration with mini services because microservices can be complex.

The solution does not work on a route-wise NFS.

There will be things that can improve, however, at this stage I cannot give a point or two. Maybe after a few months, I can give more details. One improvement I can suggest is for the people who are not very competent with technology, for the product to give some tips on the screen, to make it easier for them. Things are there and the documentation is there, however, there still needs to be quick guides available. Then it will be easier for people to adapt and learn. Rather than going to big documentation, if there is some quick help or quick guide available and then it would help people to quickly adapt and learn. It still has to improve compatibility with a couple of more platforms. It works with many however we are still trying to improvise more on a couple of other platforms. Integration seems to take a little bit of time. It would be nice if it was expanded and simplified a bit.

It is difficult to deploy the OpenShift cluster in a bare-metal environment. For example, when there are errors during the cluster deployment, it is hard to find the error on any documentation. So, from the cluster deployment perspective, there could be improvements. Also, the machine config and machine config tools need improvement. The machine config tool implements changes related to files over the worker and master nodes in OpenShift. However, sometimes it starts without warning, and it is unclear how the error can be fixed. In terms of additional features, it will be good to have the support of the CNI or OVN for the Multus CNI. Currently, in OpenShift, the additional networks added by the Multus and the pods do not support the OVN CNI plugin. OVN is supported in OpenShift, but only for the non-Multus interface, which is the primary interface of pods.

OpenShift is not very old. They have built an entire layer on top of Kubernetes. Getting the solution quickly and troubleshooting quickly are both areas where I think it needs some work. It wasn't very problematic for us because we were getting the solution. They also needed to do some experiments in their own lab, because our use case was a little different, and we were one of the few who were implementing it for the first time with Cloud Pak.

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

OpenShift's documentation could be better. It's difficult to document everything you need in a specific use case. You have to seek some support or spend a few minutes trying to figure out what's going on. Another thing that bugs me is that they removed the software in NFS storage. I don't understand why because this is a common type of storage. I am having problems with that, so I wish they would put it back.

There should be a simplification of the overall cluster environment. It should require fewer resources. Just to run a simple Hello World app, it requires about seven servers, and that's just crazy. I understand that it is fully redundant, but it's prohibitively expensive to get something simple going. We've had a very difficult time going from version 3 to 4. We need to go to version 4 because of multiple network segments that may be running in a container and how we organize our applications. It's very difficult to have applications from different domains in the same container cluster. We've had a lot of problems with that. I find it to be an overcomplicated environment, and some of the other simpler containers may very well rise above this.

It has an option to install OpenShift without connecting it to the Internet. We tried this, but it was very hard. We couldn't manage to use that option. We wanted to use it offline for installations, updates, upgrades, etc., but we didn't find the offline installation and updates easy. This could be better.

The solution has pretty good features overall. I can't recall if there are any that are lacking. The pricing is quite high. It would be nice if they could make it more competitive. The solution needs to introduce open ID connect integration for role-based access control.

From a networking perspective, the routing capability can be matured further. OpenShift doesn't handle restrictions on what kind of IPs are allowed, who can access them, and who cannot access them. So it is a simple matter of just using it with adequate network access, at the network level. It should be possible to whitelist IPs so that you can allow and restrict access to the API. That would be a fantastic feature. OpenShift would then encapsulate the entire security and access. This is one improvement that I would seriously want our client to have, and for that reason, I have joined the OpenShift community, and it is a project I could probably work on myself. The second thing is that deployment is more of a strategy rather than a feature in OpenShift. Although you can create different routes, and it works fine, it is not an innate feature of OpenShift that it understands that you want to run specific versions of the same service as needed.

Red Hat Openshift is ideal for organizations using microservices and cloud environments. I like that the platform is auto-scalable, which saves overhead time for developers. I think Openshift can be a great alternative for a fully managed container technology that will work both on premises and in the cloud. OpenShift simplifies the management of Kubernetes clusters for our developers. It is very simple to use, so even our new hires can manage it easily. The security of RedHat is comprehensive - we don’t need to worry about patching manually since we can update the entire environment together with the security patches. Some disadvantages I see in using OpenShift are that effectively using OpenShift to move from on-prem to the cloud requires a steep learning curve and there is not much documentation explaining how to do it. VMware Tanzu provides a centralized control center for Kubernetes via scalability and consistent security policy management. The easy integration of VMware Tanzu with other products is one of the features I like most. I like that you don’t need to integrate it manually with different vendors. The multitenancy and graphic interface simplify managing the containers. One disadvantage I can find in VMTanzu is that it needs to incorporate new security essentials such as supporting zero-trust architecture. Another con is that it requires a high level of Linux knowledge to make the most of it. Conclusions Despite RedHat claiming to be designed for hybrid environments, in reality, it requires a lot of knowledge to manage it properly from cloud to on-premises and back. VMware Tanzu is a better option when it comes to easy integration and scalability.

It is a costly solution but then again, it's intended for enterprise-level business, and the license has to reflect that. We implemented the solution at a college. It is appreciated what the GPU's processing power requirements will be higher. The licensing is very flexible. The license is related to the processing power you need, and the infrastructure of any clusters which go with that.

The solution is very costly. However, you do get good value for the price, and therefore we're willing to pay even if the cost is high.
