It saves us money compared to VMware because we still need to pay Microsoft licenses, but in addition to that we need to pay for VMware for virtualization.

Tomas Basus

IT Professional at NIPOS

After we set up the environments in the Microsoft ecosystem with part of the production environments in Azure and part of the development, test, and staging environments on-premises, all synchronized using Hyper-V to manage these VMs, we had this payback.

Featured Reviews

Virtualization has improved proactive maintenance and observability for complex clustered workloads

Especialista de Infraestrutura at a tech vendor with 10,001+ employees

Hyper-V could be improved in terms of performance of live migrations. I notice that in VMware, vMotion, which is the same concept as live migration, is faster than in Hyper-V. It is not that it does not work, but in terms of performance, VMware ends up being better for these virtual machine moves.I do not think there is anything else I would like to add regarding necessary improvements related to the interface, stability, or support. The interface is great and very intuitive. Support is also very quick and functional from Microsoft when a problem occurs. Once the environment is very well configured, there should not be problems in Hyper-V. The main area I would improve is mostly the performance of virtual machine migrations. If this migration performance were improved, I believe Hyper-V would reach a perfect score.

Low latency in mission-critical environments with different virtualization environments

Chief Technology Officer at a manufacturing company with 11-50 employees

The most valuable feature of KVM is its superior real-time performance, which results in lower latency compared to alternatives like VMware and Microsoft. The ability to switch from one VM to another efficiently, thanks to the implementation of a real-time kernel, ensures delays remain minimal, thereby meeting our organization's performance requirements. This improved latency is critical because any delay in voice transmission could lead to life-threatening situations. Additionally, KVM being open-source means that we are not obligated to pay for licenses, which significantly reduces costs and simplifies license handling for ourselves and on behalf of customers.
