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.

Achieves cost efficiency with optimized hardware-based virtualization
PowerVM stands out for me as a hardware-based hypervisor, which is optimized with less overhead. It supports specific workloads, like Oracle and SAP HANA, much better due to its shared processor pool feature which reduces licensing costs. In visualization, it offers a built-in accelerators feature to handle AI inference effectively while minimizing power requirements.
