Red Hat OpenShift Virtualization vs. Red Hat Virtualization (discontinued)

I believe that Red Hat OpenShift Virtualization is a very promising option for hypervisor at the moment and it seems to be improving quickly. Red Hat is doing a great job working with customers on feature set requests and improving UX and stability

Red Hat Virtualization is suitable for small implementation and hosting VMs. However, when you start asking for additional features or enhancements, the engineering team is not the flexible as other engineering teams in Red Hat. It is very likely they will not accept adding features or in the best case. They wouldn't commit to a plan when it is possible to be available.

• Easiness of deployment, we can deploy the full stack completely and hardened easier than other container products
• Used to host different workloads (CNF and VNF).
• Easy to scale on both the worker and the infra layer
• Infra nodes do not require subscriptions, which means we are only paying for our workload only, and no hidden costs.

Incentivized

• RHV issues/bugs can be reported via Bugzilla to RH support. The service is great and typically responds soon.
• Red Hat distribution integration is seamless as it is integrated into the kernel.
• OpenStack support enables more customized VM templates and network configuration control.

Incentivized

• Because of how different virtualization is done, there is a learning curve to overcome when switching to it from another hypervisor.
• Documentation needs to be improved. Just finding the details to set it up is a burden that will keep some people using it.

Incentivized

• Documentation of RHEV needs more improvement.
• RHEV GUI needs a lot of improvements in some versions of RHEV, GUI will not work properly (shows incorrect details of VM ).
• Need fast rollout of patch releases.
• Need good linux Knowledge to manage the RHEVM.

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

The product is maturing at an amazing rate, but there is still work to do to reach existing VMware customers. Most notably are the HA/DR features, and backup/recovery. We need to have faster backup capabilities, and I know this is in the works with change block tracking - but it is a challenge today. Some users are also scared by the number of volumes created by Red Hat OpenShift Virtualization, as opposed to the number of VMFS volumes they are used to.

We have already hab cases in which our customers have a better application performance even in legacy architectures running on Jboss, and even more on cloud native architectures. Customers who hosted their applications on Jboss and wildfly, when running on top of Red Hat OpenShift could benefit from more stability and availability, and in some cases, gains of performance.

The learning curve is quite high but worth it.

Some of the various other Kubernetes out there, including Rancher, is probably one of the biggest one. Rancher has a reputation for being very easy to implement. I've found that Red Hat OpenShift is just as easy to implement as Rancher. People just don't really know about it. Nutanix is another hypervisor out there competing with Red Hat OpenShift. Again, I think OpenShift virtualization but maybe isn't as old as Nutanix. I do feel it's more mature.

Red Hat Virtualization is the best enterprise-level virtualization software for an organization that needs cost-effective and flexible solutions for its environment. We can easily integrate RHEV with other Red Hat software like OpenStack...etc. RHEV is highly customizable software, which helps us to customize our environment. Since RHEV is an open-source tool, we can install it on any hardware. There is no proprietary dependency.

• It has allowed us to see where we need to be in the container world. I'm going to call it a net neutral impact, not negative or positive. It has given us a sense of what we are ready for and what we're not ready for. You know where you stand.
• You don't know what you don't know, so it helps us know what we want to know.

• It has had an extremely positive impact on my overall business and has allowed me to utilize and leverage it as an offering to my clients.
• It's an extremely solid, robust, and reliable product built off of KVM Virtualization technology.
• Less expensive solution than VMware and includes more features!
