Likelihood to Recommend KVM is the best solution in the case you need to test and turn up any virtual environment with limited vCPU/RAM resources. The obvious area of its use is a network environment when we want to avoid being tied to one type of hardware/vendor and being able to swap from one instance to another with no downtimes. The use of a vSwitch (that supports VLAN tagging) is a significant bonus for network engineers that some other hypervisors do not provide.
Read full review The VMware vCenter server is very useful in maintaining the CPU/RAM/datastore resources are balanced when there are multiple ESX/ESXi host servers. It is clear what resources are being used, and it is easy to migrate VMs to different ESX/ESXi hosts. Being able to remotely connect to the VM servers in vCenter when you cannot have other remote connections helps in maintenance and troubleshooting.
Read full review Pros KVM is really good at providing fast and reliable virtualization for Linux guests Since KVM is a kernel module, every VM is a Linux process which can be managed by Linux system tools KVM integrates very well with the management framework libvirt, which is why KVM can be integrated in automation tools as well Read full review VSAN storage management and redundancy - high performance IO with built in fault tolerance across the cluster, not reliant on a single hardware item VM fault tolerance. The ability to relocate a running VM and restart VMs from failed or isolated nodes Resource management and alerting. Tracking load across physical systems and allowing us to rebalance for better utilisation Read full review Cons Complex networking GPU processing is not fully supported It's hard to set up without support tools Read full review Currently, the HTML 5-based vSphere Client lets you manage the essential functions of vSphere from any browser, however, it would be nice if they would port all management functions over to the HTML 5-based Client. Performing updates and upgrades to the infrastructure is a bit challenging for someone that may not be as intimate with vSphere. I think the updates/upgrades should be more integrated into the UI and provide the ability to push to the hosts, etc... It would also be nice to have a more robust snapshot management tool to prevent snapshot overgrowth. It would be nice to be able to set a lifespan for the snapshot(s) Read full review Likelihood to Renew We are very dependent on this software, it has become a much needed tool to perform the daily tasks that are required to maintain the virtual server environment. VMware has become very pricey over the years, so we are looking for alternatives for cost savings strategy, but nothing has been found to be on par to what we are currently using
Read full review Usability VMware vCenter Server does a great job with maintaining your virtual environment. It has great role based features to delegate various administrative tasks to multiple users. It is an excellent 'all in one' dashboard for viewing all aspects of your vSphere infrastructure. All alerts to software and hardware issues are easy to trace from this interface
Read full review Support Rating VMware support has always been fantastic and they have been invaluable in solving tougher issues that have been run into. Most of the time, any oddities encountered are fixed by available updates. This can be deduced by support quickly with logs within vCenter. We have not run into something yet that support was unable to help with. They either have a solution already, or they are able to find one quickly.
Read full review Implementation Rating Since moving away from the Windows Server hosting the vCenter application and instead using a virtual appliance, it has become much easier to implement and deploy the new versions. We can easily create a snapshot or clone of the vCenter vApp to ensure any problems encountered during the upgrade can be mitigated with a fall back to the old version to prevent unscheduled downtime.

Hyper-V ... [VMware vCenter Server] is better for almost everything and appliance form makes a clear winner for security and ease of deployment
Read full review Return on Investment KVM just works and gets out of the way KVM is working great with other open-source technologies like QEMU and libvirt Read full review The positive impact of vcenter is definitely felt in larger organisations in terms of being able to manage multiple servers all in one environment It will decrease the amount of time your server engineers will have to spend in the server room or datacenter.
