Room For Improvement

Proxmox VE faces challenges with performance, interface complexity, support, and lacks effective monitoring, documentation, and scalability features.
VMware vSphere requires better UI, affordability, fault tolerance, cloud integration, automation, scalability, support, and enhanced documentation.
If I want to add micro-segmentation for a particular set of VMs, I need to purchase it as an add-on, but after purchasing, I cannot utilize it due to license limitations.
Information Technology Architect at Central Bank of India
The cost changed from perpetual to subscription, and there is a need for alternative solutions.

Reliable virtualization has supported smooth DR drills and efficient resource allocation
VMware vSphere has proven to be robust in nature, and the new features are quite acceptable. The new features in NSX network switching make it more useful in the reliability management of data centers. vMotion has helped my organization's business continuity strategies during our planned DR drill activity. The migration of VMs from DC to DR is quite smooth with respect to the network link. I assess the impact of VMware vSphere's High Availability feature on my infrastructure resilience as effective during DR drill activities and firmware upgrades, which we perform every six months. During those times, we rely on maintenance mode of several servers, and HA works properly. I have nothing to complain about. We have utilized VMware vSphere's Distributed Resource Scheduler effectively. Even though we have over-provisioned the vCPUs, it efficiently manages the CPU cores and memory of the servers intelligently, so I am not experiencing any bottleneck in resource utilization. Distributed Resource Scheduler has affected my resource allocation performance positively, providing a 20 percent advantage over my old hardware.

I switched from my VMware workstation to Linux KVM (on Debian, which Proxmox also uses). While there’s a learning curve, the performance gains are significant, and it doesn’t rely on proprietary software. If you’re willing to invest the time to learn, KVM and Proxmox are a solid choice, especially for small and medium-sized businesses.
