Q&A Highlights

Avigail Sugarman

Community Manager at PeerSpot (formerly IT Central Station)

Mar 05, 2019

What do each of the VMware and Citrix products do?

Sure, at a high level: VMware products allow you to set up multiple virtual servers on a single physical server. This allows you to run the virtual servers on the physical server resources. It is an easy way to replicate environments so that there are no surprises when you go to production. You can set up development, QA and UAT all on the same physical box which are identical. Citrix products allow you to process at a data center where your computing power is located. The user attaches to the Citrix network from remote location, uses the application which runs at the data center but only the screens and data is transferred. The process eliminates latency in distribution to remote user locations. Using Citrix a document can be created in Philadelphia and viewed in Hong Kong virtually without any user detectible delay because all of the processing was done at a data center in Philadelphia. Hope this helps. Let me know if you need more details.

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.

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.

Vmware and Citrix both do similar things. They both offer server virtualization and desktop virtualization (plus other related software). VMware is the clear market leader for server virtualzation (Vsphere) and Citrix is the leader in desktop / application virtualization (Xendesktop / Xenapp). They both offer network software enhancements (and Citrix has NetScaler hardware). If you have any questions, please email howieb@hotmail.com
