A bare-metal hypervisor that installs directly onto a physical server. With direct access to and control of underlying resources, VMware ESXi partitions hardware to consolidate applications and cut costs.
Red Hat maintains a consistent user interface across their products, and their feature sets facilitate easy and rapid adoption. Configuration as code is the optimal approach for all of them, and they all provide a level of command-line access that ensures teams can work in the …
OCP and OpenShift Virtualization are better for a code based infrastructure our organization is attempting to move towards shortly. VMware has also been acquired which has added instability with their future. We are planning to move all VMware workloads to OpenShift …
I don't have as much experience with the other two, I have heard of them and know they are container management systems. I have the most experience with Red Hat OpenShift.
Red Hat Enterprise Linux (RHEL), Red Hat Data Grid, Red Hat Integration, Red Hat JBoss Enterprise Application Platform and Red Hat Ansible Automation Platform
As a specialized partner in container platform Red Hat OpenShift is our preffered solution. It provides a supported kubernetes platform which contains all the required tools to make the life of customers easier and offer them the same experience accross all hyperscalers, …
I find OpenShift opinionated but also requiring less configuration to be functional than the other platforms that I've mentioned, and Tanzu requires Faustian contracts to be signed.
Neither of these two products have really been a 100% replacement for VMware ESXi but they are getting closer and closer and with the new licensing agreements that VMware is trying to push out, could start eating at the lower hanging fruit. VMware ESXi still has some nicer …
VMware stacks really well compared to competitors as it has a good reputation in the markets, and clients trust the virtual machines in regard to their data. It also provides better reliability and performance as compared to the competitors, which makes it a clear choice for …
I think it is better than Hyper-V. The gap has possibly narrowed, but it is a more robust product. Time will tell if that stays the same after being acquired.
While running through a proof of concept with Hyper-V and VMware ESXi, I found VMware ESXi to be much easier to deploy, administer, and work with overall. Both products are good but I personally found ESXi to be more intuitive to use and the deployment options were also more …
VMware ESXI is straight forward dependable hypervisor, with some users experience consistent server uptime even during hardware failure and other setbacks. It requires few hardware resources, making a minimal impact on its host machine. Deploying new servers with VMware ESXI is …
At the time we did our comparison we found that VMware scaled much better than Hyper-V, lighter weight, and much more reliable. My recommendation if Hyper-V is needed for anything such as Windows containers, is to use nested virtualization and installing Windows Hyper-V within …
VMware ESXi excels in comparison to Microsoft's offering due to integration with Linux, its bare metal approach and its ability to function off of a thinner hypervisor. It allows for better integration with application appliances in my opinion due to its non-Microsoft nature. …
While Hyper-V also can work very well and can have licensing benefits, it does rely on Windows in order to run. This isn't necessarily a bad thing, but it can add another layer of potential failure and might not be running on as low of a level as ESXi does. The footprint for …
It's hard to beat Hyper-V when it comes to ESXi. Although Hyper-V costs nothing to use, it does require a Windows license that permits you to operate at least two virtual machines (VMs) on the Hyper-V server. I found that VMware ESXi consumes fewer resources than any other …
VMware ESXi is a lot more robust and resilient than MS Hyper-V. However, Hyper-V is more convenient and economical because it comes with Windows Server.
The vSphere management interface is going to be web-based and you access that through a web browser by browsing to the IO address of the VMware ESXi host itself and then from there you'll be prompted for a login screen.
As long as you're using Nutanix AOS on Nutanix hardware and are paying their software support fees, AOS is a valid competitor to VMware and can save money due to not needing a license and having their server management system built into the base host management system. If you …
Compared to VirtualBox, VMware ESXi feels a lot more enterprise-grade when comparing the two. As ESXi is a VMware product we knew the level of quality and support we would receive from the vendor. VirtualBox is an open-source platform for virtualization and we liked the fact …
VMware ESXi stacks up nicely against Hyper-v. VMware ESXi is a smaller footprint, the one thing Hyper-v has is cost it is free with the purchase of a windows license that allows you to run at least two windows VM's within the Hyper-v server. But VMware ESXi is still the leader …
Hyper-V utilizes more resources compared to ESXi and it gets affected when it is used to scale up and installation on Microsoft windows is easy however it does not stand to the ease of access of ESXi, a user of ESXi would find it difficult to migrate to another application.
VMware has been the #1 vendor for virtualization for 10 years, is used in top incorporations, supports almost every software around there, and runs smoothly with every hardware vendor. The con is the price, it's the most expensive solution.
Easy to manage, standard licenses and bundle licenses are customizable, provides a much more stable infrastructure. Cost-effective, Comes with special features like HA, DRS, FT.
Much more reliable and well-integrated than competitors, with a solid central management console. Citrix is having good performance but requires a specific kernel to leverage, HyperV is good only for windows OS.
We moved to VMWare ESXi from an all-physical environment. I know that VMWare VSphere is an even more advanced solution for managing numerous VMHosts under a single GUI - but we have not invested any time into VShere as of yet. We have too few employees at the moment to …
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.
If you're looking for the industry standard in server virtualization, I would recommend ESXi. After decades of expertise in the field, VMware continues to provide a strong product, production-ready, with an easy-to-learn interface that allows for quick management along with less costly upfront onboarding and training. Grab the free personal-use license and install in your homelab to start!
One of the big advantages of Red Hat OpenShift is, especially over Kubernetes itself, is that it provides a lot of built-in operators for doing a lot of different things right out of the box that you don't have to worry about trying to configure. So one of the big ones is, I mean, right in your face is that user interface and being able to work with it inside of a browser. And I think that works very, very well.
I would say that's the logging part because Red Hat OpenShift write tons of locks and if most time in the finance industry, we cannot use the built in logging infrastructure for compliance reasons. And we have to forward the logs out of the system and this is, it's too much, which we forward from one cluster. Most time we'll build up multi clusters, so we speak about 10 or more clusters. And if you send log files from 10 or more clusters, the logging systems are not prepared to take that much load. And then really often you have license problems with the logging system, so that's not really, really fun. So logging could be improved.
There are some odd issues with VMware's virtualized network drive (VMXNET3). On occasion, after a reboot of a Windows-based VM the NIC will fail to bind properly and network access is unavailable until an admin intervenes by disabling/re-enabling the adapter. While it's possible that our environment is a contributing factor, this never happens on VMs using Intel E1000 emulation, only the paravirtual NICs.
Logging is extensive but difficult to work with. VMware's solution is a product called Log Insight, which comes at additional cost. Fortunately this is somewhat mitigated by the extensive support documentation and robust user community, but in the heat of the moment obtaining the required detail can be a trying experience.
Going to stay with this platform for the unforeseeable future. It matches our Target Architecture 2030 strategy internally to adopt more modularized platforms with Open Source on the back-end so that if needed containerized workloads can move to a different platform. With open-source based application telemetry collection being utilized on the back-end, integrating our already existing oTeL observability based platform makes it easier for our apps to be monitored
It is critical to our business, what started out as a way to do certain functions, it has now become core to ensuring our product is available to our customers and reducing our costs to operate and reduce our recovery time and provisioning servers. Their support is great and the costs to renew is reasonable.
As I said before, the obserability is one of the weakest point of OpenShift and that has a lot to do with usability. The Kibana console is not fully integrated with OpenShift console and you have to switch from tab to tab to use it. Same with Prometheus, Jaeger and Grafan, it's a "simple" integration but if you want to do complex queries or dashboards you have to go to the specific console
The interface is fairly intuitive for most things, and the areas that are a little less obvious usually have fantastic documentation in the online knowledgebase. In 3-4 years of managing our ESXi hosts, I think that I have only opened 4-5 support cases for things that I could not figure out myself or find answers to on the website.
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.
Without the need to patch the servers with bug fixes and enhancements we whave not experienced any downtime with VMware issues. Even the bug fixes and updates do not cause of downtime as we just migrate the servers to the opposite node and update the one and then move servers back. Very simple and painless.
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.
We do not notice any difference between a physical and virtual server running the same workload. In fact we can scale quicker with the virtual server than we can with the physical.
Their customer support team is good and quick to respond. On a couple of occassions, they have helped us in solving some issues which we were finding a tad difficult to comprehend. On a rare occasion, the response was a bit slow but maybe it was because of the festival season. Overall a good experience on this front.
I rarely ever need support for anything VMWare makes, but when I do, the documentation available just in the free community is generally enough. It's extensive and the community is truly robust and active. And if you have a myvmware account, you can get support for your owned products from VMWare support by the conventional case/ticket method
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.
Jsut read and follow anything your storage provider may require to allow the integration of VMware with storage operations, outside of that VMware jsut works.
We utilized the Thycotic Secret Service to manage all our application secrets, resulting in seamless integration with our applications. We developed all the applications using Red Hat Fuse (currently migrated to Quarkus). We used the built-in Kali Linux support of OpenShift to manage and configure the services and API. Additionally, the Red Hat Developer Studio facilitates faster development.
While Hyper-V also can work very well and can have licensing benefits, it does rely on Windows in order to run. This isn't necessarily a bad thing, but it can add another layer of potential failure and might not be running on as low of a level as ESXi does. The footprint for Hyper-V can be smaller if the Desktop Experience isn't used for the hosts, but this is the default fashion that ESXi has been running for many years. VMware's support has always been stellar, and its documentation is phenomenal. Hyper-V can work as a virtual environment option, but ESXi has never let me down in any environment I have managed. I will continue standing by this product and prefer it over other options. It has proven itself time and time again over time as the defacto virtual environment hosting platform.
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
We started out with a two-server cluster and adding a third or fourth is very straightforward and simple with no issues. You just need to be aware of the size of your Vcenter Server to handle the workload, but still the resources needed is very minimal
When you talk about ROIs, I don't have any negative impacts I wanted to call out here. There is no negative impacts. In fact, it's all positive impacts what we set as our milestones towards achieving our goals, towards achieving our greater vision. Red Hat OpenShift has got a big role in it and it is certainly helping us.
Positively, it has saved us time in spinning up new servers for the different departments in our company. It is easy for us to spin up virtual machines with VMware ESXi and deploy applications at the drop of a hat.
Positively we are able to save space in our data closets as we no longer need to keep room for physical servers and workstations, allowing us to expand in other areas like networking equipment and physical backup solutions.
It has moved our business forward as we are able to migrate old servers and static workstations in the virtual environment allowing us to easily keep an eye on older applications and update/backup easily through VMware ESXi management console.
