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.
"This solution allows the end users to clone, start, stop, or remotely control their VMs."
"The most valuable features are being able to host many virtual machines and being able to patch machines."
"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."
"Ability to move your virtual machines from one host to another."
"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."
"We find there are good central maintenance and central management panels."
"Citrix Hypervisor integrates easily and I can manage the infrastructure better. If I need to take a machine down to expand the hard drive, I do not have to physically be here. I do not need to order new equipment or new hard drives. I can shut it down, increase the drive space and bring it back up."
"Scripting can automate procedures."
"The most valuable features for us are DRS, VMotion, and, of course, some of the analytics that we were able to define to quantify our workloads and tell us how we are able to make our data center more efficient."
"The scalability is good."
"It's not a particular feature, really, however, I can say that the solution is just easy to maintain, and makes it easy to backup all those VMs. We can easily save our data and we can deploy VM machines very fast and create the delivery of the server in a pretty simple, dynamic way."
"Valuable features really depend on different projects. We are using the traditional infrastructure based on VMware vSphere. We are also using the high availability (HA) and Distributed Switch features to extend our network and switch between different hosts. The VMotion and SVMotion features are very essential for us to relocate the storage of virtual machines to different storage or vSANs. We are using VMotion and SVMotion features several times of the day. We are also using another VMware product to replicate a lot of solutions to a second replication site."
"vMotion is one of the most useful features, which helps to provide both flexibility and High Availability. With new versions of vSphere and vCenter, it is still improving (e.g., vMotion across vCenter Servers and virtual switches)."
"The most important feature is the ability to balance the servers with Distributed Resource Scheduler (DRS). It is a very useful feature and should be mandatory for vSphere to have but it is only available in the enterprise edition. It should be available in all versions."
"VMware vSphere helps us in not wasting resources like we did when we were using physical servers. It changed our whole environment."
"We find the solution simple and efficient to manage."
"The licensing costs are too high on the solution. They should work to make the costs more reasonable."
"Assigning the order of virtual server startup is not very easy and this can be improved."
"Live migration is something that can be improved."
"It needs to have a more robust backup solution."
"Network management needs improvement because it is not very stable."
"Citrix is not investing in the virtual surroundings."
"The interface has to be updated."
"The solution would benefit from faster technical support."
"Here in Egypt, we would like everything free. So if you give us the license for free, we would be thrilled."
"The solution is slower than other tools."
"It would be nice if it had auto-scaling, no need to select CPU or select database size. Let it auto-scale, let it use the features that VMware has, instead of having to preselect."
"The biggest issue with stability is the SSO. That is still an issue as far as integrating it with Active Directory, and any large scale of it."
"Given that I've been using version seven, it seems that some of the bugs I faced during that version have already been addressed in subsequent updates. Although I haven't personally tested them yet, it appears that these issues have been resolved. In version seven, there was a problem with the network interface not responding due to certain configurations not being properly filtered. However, in version eight, this requirement has been minimized, so the mentioned bug is less likely to occur. Instead of solely addressing these fixes in newer versions, it might be beneficial for them to consider applying these improvements to the older versions as well. This approach could prevent users from feeling compelled to upgrade to version eight solely to avoid encountering the issue, and instead provide updates for version seven users."
"The initial setup is a bit complex."
"The biggest room for improvement would be just simplicity. It is very intuitive, but it needs somebody with a lot of IT background."
"The solution could be a bit more user-friendly."

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
