While they are generally stable, if outages occur, they tend to be due to brands like HP or Dell, not VMware vSphere itself.
Revenue Operations Specialist at KK AGC
Mostly we don't have issues, but sometimes we have faced some stability issues because of some bugs and some CPU compatibility issues with Intel CPUs.
IT Director at Def Industry
 

Room For Improvement

Citrix XenServer requires better backup, Linux support, network management, third-party integration, and user interface modernization to enhance usability.
Proxmox VE faces challenges with performance, interface complexity, support, and lacks effective monitoring, documentation, and scalability features.
VMware vSphere is costly and complex, facing performance, integration, and upgrade challenges, limiting accessibility for smaller enterprises.
Although the product is technically competitive, it is not widely known or used due to poor marketing.
Virtualization Architect & Managing Owner at AnyThin', Jerzy Fronczak
Citrix needs to improve the hypervisor, specifically in security and performance.
Solutions Manager at ICSI
We can implement high availability and live migration with pools, along with security and backup to enable role-based access control for safer management.
Citrix Specialist at a tech vendor with 10,001+ employees
The cost changed from perpetual to subscription, and there is a need for alternative solutions.
Manager of Solutions and Support at Esconet Technologies Pvt. Ltd.
Another area is the stability during upgrades from older versions to newer versions, where we face issues.
Manager of Systems at Sir Syed University of Engineering and Technology
Sometimes, it is difficult to find documentation for specific tools and solutions.
Server Support Engineer at CIPL - Corporate Infotech Pvt Ltd
 

Setup Cost

Citrix XenServer is a cost-effective virtualization solution with free basic features, but commercial support and scaling increase costs.
Proxmox VE is an open-source, cost-effective virtualization solution with optional support, valued for its affordability against competitors.
VMware vSphere's complex pricing offers flexibility and features, but businesses should evaluate needs to avoid unnecessary costs.
It is cheaper compared to its competitors.
Solutions Manager at ICSI
Organizations save substantial money because competing solutions, such as VMware, cost double or triple.
Co-Founder at Virajo
The pricing and licensing policy of Citrix XenServer is not transparent and quite confusing.
Virtualization Architect & Managing Owner at AnyThin', Jerzy Fronczak
Many customers are trying to avoid it due to its high cost.
Technical Assistant at EOCD
Costs significantly increased from perpetual to subscription, with prices rising by two to three times over three to five years.
Manager of Solutions and Support at Esconet Technologies Pvt. Ltd.
The solution is too expensive.
Revenue Operations Specialist at KK AGC

Support team resolves issues quickly and receives positive feedback
We can improve Citrix XenServer Performance Management in the server base by enabling CPU virtualization extensions such as Intel VT or AMD-V. We can use Paravirtualization (PV) drivers to enhance network performance. We can implement dedicated storage not shared with other applications and use thin provisioning for more efficient storage usage. Regular updates should be given to patches and hotfixes. XenCenter or web-based solutions provide better control and monitoring, which is useful for automatic tasks with PowerShell scripts. We can implement high availability and live migration with pools, along with security and backup to enable role-based access control for safer management. We can schedule VM snapshots and use VM export for backup and recovery. While Citrix Hypervisor remains a reliable virtualization platform, several areas could be improved to better meet enterprise needs. The user interface, though functional, lacks a more modern web-based experience compared to tools such as Proxmox VE or VMware vSphere. A more responsive browser-accessible interface would simplify management, especially for remote administrators. Citrix Cloud needs improved support for containerization technologies such as Docker and Kubernetes, which are essential in today's hybrid cloud environments. Backup and disaster recovery features are somewhat limited, often requiring third-party tools. Better built-in snapshot management and cloud integration would enhance usability. Community support and documentation have fallen behind compared to open-source projects such as Proxmox. More transparent development and a stronger ecosystem would greatly benefit users. The streaming licensing and feature access make Citrix Hypervisor more competitive in a growing market of free and open-source hypervisors.

Effortless management with robust support enhances performance and cost savings
My primary use case for Proxmox VE focuses on replacing VMware solutions and migrating to a Centric Solution for medium-sized companies. This product serves as a hypervisor in environments where performance is crucial Proxmox VE has provided performance improvements, particularly with its…

IT Director at Def Industry
Has improved infrastructure monitoring and resource management but requires better support and cost efficiency
The high availability feature's resilience is not bad, but it could be better. For example, whenever you lose any hardware, you will have interruptions on the services, and it reboots again on the other hardware host which is available at the crash time. That's good, but we would prefer to have zero downtime instead of the rebooting on the other server. We would prefer to have a zero downtime always-on configuration. VMware vSphere has a built-in feature called Fault Tolerance, but it's very limited for very limited VMs or very limited core count or CPU count, so it's not so useful for all the environment because of the limitations. The Fault Tolerance (FT) feature is very limited to very little core counts or very little VM counts, so you can't run the Fault Tolerance for all the servers or all the VMs, and that's very bad. If VMware vSphere could have any kind of built-in patch management environment with a repository, offline repository option, with test, non-production, and production environment separated, this would be perfect. Management of patch management with operating systems and including third-party applications which are running on the servers would enhance the VMware vSphere environment. VMware vSphere is very expensive. The worst aspect of VMware vSphere is the price. I can't tell you the exact cost at this time because the other team members in my teams are working on it, but I remember that the prices are very high. VMware vSphere is easy to scale, but it could be better, similar to a Kubernetes environment. It should have an automatic scale-out feature when the load gets high; if it gets some scale out automatically, it would be better than this, similar to Kubernetes or OpenShift.
