Citrix Specialist at a tech vendor with 10,001+ employees
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.
Ion Boni - PeerSpot reviewer
Managing Partner at evercloud
Has improved daily operations and provides solid performance but recent licensing changes have created challenges
Licensing has become a major issue. The new subscription-based licensing model is problematic. They have dropped all the support services for small partners and cut all small partners. The last two years have been challenging - after building stability, we received an email announcing they dropped the current model. It used to be cost-efficient. Now, when compared with Red Hat OpenStack, it is more expensive, but our knowledge and client awareness is with VMware ESXi. At this moment, we still prefer VMware ESXi.
