We performed a comparison between Citrix Hypervisor and VMware vSphere based on our users’ reviews in five categories. After reading all of the collected data, you can find our conclusion below.
Comparison Results: Citrix Hypervisor wins out in this comparison. The main difference between the two solutions is that VMware vSphere is more expensive than Citrix Hypervisor and users say it also needs improved security and monitoring features.
"The continued uptime of our virtual machines is good."
"What I find most valuable in Citrix Hypervisor is its licensing policy, because you'll get it for free if you buy a Citrix XenDesktop license. You don't need to spend additional money on the Citrix Hypervisor because you can manage both the Citrix XenDesktop and the Citrix Hypervisor with just one license, so you can save on cost. I also like that the solution is good support-wise. Hardware support is also faster compared to other solutions."
"Citrix Hypervisor does a great job overall, such as the virtualization of the host. It's very easy to manage the virtual machine, to create, and configure high availability."
"The ability to move a virtual machine while it is running is a big advantage."
"I've found the following features to be the most valuable: user personalization layer, app layering, provisioning, and notification services for integration between different domains."
"Installing Hypervisor is really simple. It's the simplest setup I've ever done before. We used a team to deploy it, and it doesn't take much time, like two or three hours tops."
"The solution integrates well with other solutions, which makes it really strong as a primary solution to deploy."
"Citrix is easy to use and is stable."
"What I like about it is being able to see my entire organization, especially with some of the newer enhanced links. All of my data centers show up in one view and I can see every server that's running. I also get performance statistics so if there are issues, major problems going on, I can see them."
"The most valuable feature is its ability to revert to previous snapshots during testing of various guest and application deployments."
"The initial setup is easy."
"Reduces downtime."
"It is very stable and scalable, and implementation is straightforward as well."
"I find that the Virtual Center Management, iSCSI support, and VMotion hot migration are very beneficial."
"The performance of VMware vSphere is good."
"Ease-of-Use; The solution is very simple to use and to manage. Updates are simple. The biggest feature that enables the ease of use is the fact that you can update via the web interface. With a couple of clicks, the update is done; no manual intervention, you just click Update and it automatically reboots the server for you and you're back up and going again."
"Overall, I can't think of a feature that is lacking. We've been pretty satisfied overall."
"I think the technical support could be better."
"I am not very sure about how flexible Citrix Hypervisor is with different types of infrastructures. I only know it is flexible with Nutanix, but I am not sure if it is also flexible with others. They can make its integration with other platforms or OEMs easy. They should also make it easy for users to manage their infrastructure. Citrix should make compatibility information related to a hypervisor easily available in a datasheet. Citrix isn't really recognized in this part of the world, and they need to expand their solution and make it more available. There are a lot of customers and companies that are looking for a solution like Citrix, and it should be available in this part of the world. They need to educate people more. Technically, it is good and flexible and has good ability, but it is not as much known as VMware or Microsoft. Their support should also be improved. Currently, if you don't have an updated version, they will not give you the attention."
"Live migration is something that can be improved."
"It needs improvement with the security features."
"There are several areas that need improvement including the stability of the networking stack and networking management."
"Integration with other vendors and other applications could be improved."
"You need a licensed account to look up technical support."
"In terms of what could be improved, we do face some bugs when cloning the virtual machine - it fails sometimes."
"The support is good, but it's slow."
"As we continue to push mission-critical workloads into vSphere, and those workloads are not readily protected at the application layer for availability, continuing to increase the size limitations on FT-protected VMs would be a great advance."
"I'd like to see a little bit more integration for VDI. I think that Composer servers, security servers, broker servers with connections, I'm not sure they are necessary at this point. Perhaps they could have a lot of those functions baked directly into the hypervisor. It seems to me that if the hypervisor is scalable and flexible enough, that the processor and compute can handle all of that. Maybe we eliminate those other components for VDIs and have more mixed workloads: server workloads and desktop workloads all in the same hypervisor."
"The initial setup could be better. It manages all the setups, but it's not very straightforward, and it takes time."
"The solution could improve by having more integration."
"In addition, I think some of the backup features or the prediction features can be improved."
"The technical support is not too bad, but not the best."

VMware and Citrix server virtualization do almost the same thing with nearly same options, on the other hand Citrix Xenapp and Xendesktop is far more advanced and efficient and have their own secured protocol. I've been using Citrix Xenapp for long time, it is an amazing solution saving huge cost related to communication channels and software license. Also I implemented Citrix Xenapp on VMware and HyperV. The stability of Citrix over VMware is far more better than over HyperV. We used the Citrix Xenapp to streaming Oracle EBS and Microsoft office to remote users (about 13000 user) it served up to 1600 concurrent user very efficient.
Hi,
VMware and Citrix XenServer both are Bare metal (Type1) Virtualization Software. Both are good. But VMware is too user friendly and good for Enterprise as well. Whereas, Citrix is good for SMB.
In short, there are so many options with each company that it is hard to provide a short sweet answer. From my experience, Citrix has been used primarily to enable one to access computers and systems remotely as well as a tool to enable folks to get together via an online meeting format. VMWare, conversely, has been used for virtual environments where one could host their servers, say up to 4 or 5 of them, virtually, on each ESXi host machine. Again, each company has many products, however I have thought of them as an apples verses oranges comparison in as far as the service/products they offer. One can explore Citrix products at www.citrix.com and VMWare products at http://www.vmware.com/products/.

Adding to Howard's points, you can virtualize NetScaler as well. It is now replacing Cisco's Load Balancing line of products. Citrix XenServer also allows for users to build their own Cloud.
As with Rakesh's comments, Citrix can provide some of same benefits.
1. Reduce physical space in the data center, thereby reducing physical server maintenance, cooling costs and OPEX.
2. Using templates, you can deploy virtual servers in hours instead of days or weeks with physical purchases.
3. With Desktop virtualization, Microsoft has VDA licensing. Server OS licensing remains the same.
Overall, both vendors have their own key points of expertise, it will depend on what you really want to accomplish with virtualization.
Which products specifically?
Haven't used citrix but had been useing VMWARE , I will therefore concentrate on VMware alone.
VMWare benefits on Multiple fronts
1. Reduce Physical Space of Data Center
2. Reduces Physical Server Maintenance Cost and thereby OPEX
3. Make implementing Redundancy much Easier
4. Servers are Up in Days compared to conventional methods where we needed to procure physical Servers
5. Reduce Energy Cost as we have reduced number of Physical Servers
6. Reduces Windows OS licensing cost
Adding to Howard's points above, VMware uses their existing Hypervisor platform to enable customers build their own Cloud too.
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
