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.
Consul can provide a light-weight, lightning-fast and robust solution for the following:
Network mesh
Service DNS
Global key-value store (values can be complex objects as well)
Utility for blue-green deployments
Service health checking
Consul can be used in any or a combination of these scenarios. Regardless if you are a network administrator or a regular software engineer, Consul can add value to your work.
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.
We had a few microservices that dealt with notifications and alerts. We used OpenShift to deploy these microservices, which handle and deliver notifications using publish-subscribe models.
We had to expose an API to consumers via MTLS, which was implemented using Server secret integration in OpenShift. We were then able to deploy the APIs on OpenShift with API security.
We integrated Splunk with OpenShift to view the logs of our applications and gain real-time insights into usage, as well as provide high availability.
The GUI: The GUI interface for Consul has gotten a lot better over the years. Since Consul is so easy to interact with via API, this isn't a showstopper, but for those that are less command line inclined it's always nice to be able to refer them to an easy to use and understand web interface
It's chatty: Consul is extremely chatty. Sometimes it's particularly chatty at 2am with no indication as to why and eats up quite a bit of resources. Just be sure to provision your systems that typically take a heavy load with a little extra for Consul
OpenShift virtualization has a little room for improvement. I'm coming from it as a Rev customer. There's some things in that OpenShift virtualization that were in Rev that I would like to see in OpenShift virtualization. I realized that they're chasing the VMware crowd and that's fine, but from us old Rev customers, we'd like to see some things that was in Rev around via migration and things of that nature that could be in OpenShift virtualization, I hope is being planned to be put in.
OpenShift is really easy of use through its management console. OpenShift gives a very large flexibility through many inbuilt functionalities, all gathered in the same place (it's a very convenient tool to learn DevOps technics hands on) OpenShift is an ideal integrated development / deployment platform for containers
Consul's API is extremely user friendly. While their web interface isn't quite as "mature", it's still pretty easily navigated for the average person. Together they make a pretty easy to pick up and use tool.
The virtualization part takes some getting used to it you are coming from a more traditional hypervisor. Customization options are not intuitive to these users. The process should be more clear. Perhaps a guide to Openshift Virtualization for users of RHV, VMware, etc. would ease this transition into the new platform
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.
I've never used paid support from HashiCorp, but I consider its support a good one, since they provide a lot of free resources for the community and there are good user groups supporting you on several sorts of issues. Also, HashiCorp is known as a company with a strong relationship with the community, that is easily noticed by the events HashiCorp promotes over the world.
Every time we need to get support all the Red Hat team move forward looking to solve the problem. Sometimes this was not easy and requires the scalation to product team, and we always get a response. Most of the minor issues were solved with the information from access.redhat.com
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.
Consul was easier to configure out of the box than Serf and gave us more initial options. Its easy to use tools and support were by far superior to Serf in many ways. Support alone was one of those areas that Serf could take an example from Consul to keep its customers happy.
The Tanzu Platform seemed overly complicated, and the frequent changes to the portfolio as well as the messaging made us uneasy. We also decided it would not be wise to tie our application platform to a specific infrastructure provider, as Tanzu cannot be deployed on anything other than vSphere. SUSE Rancher seemed good overall, but ultimately felt closer to a DIY approach versus the comprehensive package that Red Hat OpenShift provides.
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.
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
It contains a native web UI, which in contrast to its counterparts, is handy, very intuitive and - most importantly - very informative. It leaves no room for doubt about your services "forest" health. So, for that purpose, the learning curve was almost down to non-existent. Our team managed to work seamlessly with Consul being our services API
Our management staff had a difficult time understanding what Consul was really all about. For technical staff it is pretty simple to understand the huge value such a tool can pose to our suite of solutions, but once our management staff took the grasp of its valuable handy set of tools, we didn't take long to start using it and keeping track of our Swarm overall health, with was a constant concern for the entire company before.
For load balancing purposes, we were relying pretty much on guesses before we decided to use Consul. One would check a certain node overall health and decide if we would need to spring a new instance at AWS or Digital Ocean.
All of the above. Red Hat OpenShift going into a developer-type setting can be stood up very quickly. There's a very short period to have developers onboard to it and they're able to become productive much faster than a grow your own type solution.
