The most important feature is high availability (HA) which monitors the system and restarts virtual machines to a healthy host whenever the system senses an imminent hardware failure. Another great feature is DRS which is VMWare’s load balancing software which keeps our virtual machines running on the server cluster in a balanced manner. This automated system keeps all our systems running with a high uptime. View full review »

The most important feature for us is clearly the foundation it provides. In addition to that, we've found the High Availability and flexibility to be important as well. View full review »

System Architect with 11-50 employees
Our infrastructure is based on KVM and Linux Containers (LXC). We had a lot of VMware legacy, but it was converted to Ubuntu and KVM hypervisor for about the last year. Management and backup is a lot easier with with Ubuntu and KVM, especially combined with ZFS and snapshotting. View full review »

Technical Support Analyst at a tech vendor with 1,001-5,000 employees
The template option allows us to build a desktop in a VM, then quickly deploy as a linked clone. The hard drive file on the template is used (read-only), then all changes are saved in a separate hard drive file. It is like deploying a new VM based on snapshots. View full review »

We find the most valuable feature is just hosting the VM. The replication I do with other software. View full review »
Software512a says in a KVM review
Software Architect with 501-1,000 employees
I find the density of the product most valuable. It is because of kernel same page merging technology (KSM) that is integrated into Linux kernel. That high density makes KVM one of the important players of the virtualization market. View full review »

Head - Server and Storage at a financial services firm with 1,001-5,000 employees
I really value the DRS feature of the solution. Apart from that, there is a high availability in the feature called VMotion. In addition, the centralized management throughout the V-Center software is useful. View full review »
Sandeep Shenoy says in a Hyper-V review
With the virtualization what we could achieve was maximum utilization of our resources. Previously we used to like have ten, fifteen physical service each one was utilized for a certain percentage and uh, not everything was utilized. I mean one service was maybe 20% utilization one was 90% utilization. So, there was no balance of utilization. With virtualization we can balance. In addition, we can be accurate at the with the solution or Hyper-V, this gives us a close decision I can move motion machines live from one physical machine to another. View full review »
MS Alam says in a Hyper-V review
System Administrator at Abdullah Al-Othaim Markets
I think the cluster environment is a good feature of Hyper-V because, if something happens, then it will automatically move to some other mode. This is a great feature of the solution. View full review »

Virtualization of our environment has made our carbon footprint, the real estate necessary and the ease of deployment in time savings significant. View full review »
Matias Sundman says in a KVM review
System Architect at a aerospace/defense firm with 10,001+ employees
A big strength with KVM is that it is an open-source component. It gets improvements from Intel, for example, and the other semiconductors. It can be sized-down to a very small package. It can be used in embedded systems as well, so it has a very good performance and it is suitable from embedded IT to big servers and supercomputers. This solution integrates nicely with other soft-open-software components. View full review »
Brian Kirsch says in a vSphere review
Instructor at MATC
* A big feature for us was Quick Boot. You don't have to wait for the host to do a recheck on memory. You do an upgrade, and it's not a 10-minute reboot cycle. You can bring your host online and offline. * Database optimization. They did a lot in enhancing the performance. They took down the memory utilization and increased what it brought in. You see more responsiveness, especially now with having the HTML5 client. It feels like a much snappier product. The biggest feature that everybody wanted was the HTML5 client. This has made everything native where you're able to surf through it. Going into our web page, you're no longer refreshing it. It feels more like an enterprise product now. With Adobe Flash, it didn't feel that way. View full review »

Chief Architect at RoundTower Technologies
* The move towards feature-parity with HTML5 for the user interface. * Also, increasing the release of features, which is partly through the use of that technology stack with VMware Cloud on AWS, so it's a much more robust product right now. * It is a lot more simple and efficient to manage. It has improved a lot from the early days of vSphere 5.x. Lifecycle management and reducing the number of clicks that an administrator has to do to actually do a task have been greatly optimized, particularly with the HTML5 interface. * In terms of more easily managing networks and improving visibility, the two go hand in hand. Compared to the vCloud Air days, it's come a long way. It's a solution that actually works now, and you can use your vSphere staff - who have been trained on and understand vSphere - to actually consume that hybrid cloud with very little or no training.

Allan Trambouze says in a vSphere review
Senior Consultant at Cofomo
The most valuable features are: * ESXi Quick Boot * VM encryption * New security features. The new feature announced today with vSphere Update 1 inside vSan is impressive. I did not have a chance to test Update 1 yet. We shall see how it performs in the next few days. Because my server is too old, I am using my own lab for TPM. I did not have a good chance to test everything. VM encryption is quite simple to implement: Just check two boxes and it is done. It is very easy to do. If you want to move from on-premise to cloud, it is quite easy. View full review »
Stephen Parker says in a vSphere review
Systems Engineer at BYU Idaho
The HTML5 interface is much better, it's faster, faster than the old C# Client, which was very nice to have. But with the HTML5 interface, it's smooth, fast, responsive. I can do it from any device, from my Mac, my PC, even from my phone. The solution is very simple to use and to manage. Updates are simple. The biggest feature that enables the ease of use is the fact that you can update via the web interface. With a couple of clicks, the update is done; no manual intervention, you just click Update and it automatically reboots the server for you and you're back up and going again. View full review »
Blake Grover says in a vSphere review
System Admin with 1,001-5,000 employees
This version has added a lot more features to the HTML5 interface and that helps us monitor and manage the system better and faster than with the old interface. I also think it is very easy to manage. When it moved over to HTML5, bringing all those new features into the HTML5 interface, that improved it a lot. I don't know specific performance data points, but I would say it has helped tremendously in being able to stay in one interface and not having to manage multiple, different interfaces in connecting to it.

Stephen Krujelskis says in a vSphere review
Senior System Administrator at a university with 501-1,000 employees
Most valuable features are * quick provisioning * High Availability * DRS for balancing workload. I definitely find vSphere to be simple and efficient to manage. A key feature that enables this is vCenter. It is super simple to stand up, and once you're in there, especially with the new HTML5 client, everything is easy to manage. View full review »
Jason Hong-Turney says in a vSphere review
Lead IT Systems Engineer at a tech consulting company with 10,001+ employees
Most valuable features of vSphere 6.7, for us, at the management level would be: * VCHA is a nice redundancy feature that they added in 6.7. * I like the quality of life improvements with the VMFS-6 for using auto UNMAP on the data stores. * We really appreciate the improvements to the Clarity UI where we can manage Update Manager (VUM) and our vSAN stack within the modern interface. The solution is also very simple and efficient to manage. Features that have made it simple and easy to manage include the newer VAMI for the V-center appliance, it's very easy to see what version we are at, and very easy to upgrade to the next version. The fact that we can now use VCHA at the appliance level just decreases our chance of having an outage, because so many of our customers rely on the API interface for V-center. View full review »
