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 most valuable feature of the solution is that it is very fast. It also works very well for physically small servers."
"This solution allows the end users to clone, start, stop, or remotely control their VMs."
"The solution is extremely stable."
"Ability to move your virtual machines from one host to another."
"This is a good product for virtualization and it is easy to use."
"The solution is easy to deploy. It's very easy to understand problems and read logs."
"We can easily migrate VMs from one host to another."
"It is quite flexible and rugged. It is also easy to understand and user-friendly. It is not as complicated as some of the other solutions. It has its technicalities, but it is easy to understand. You can easily pick up in a short period of time and understand how to manage the infrastructure."
"Basic hypervisor functions with HA."
"There are no issues with the level of scalability you can achieve."
"VMware vSphere helps us in not wasting resources like we did when we were using physical servers. It changed our whole environment."
"Server Virtualization is the most important feature because that helps me to utilize 100% capacity of my physical server or box. Its redundancy, uptime, or high-availability is also valuable. Storage-sharing is also valuable. In vSAN, I can utilize the maximum storage. In the physical boxes, if you don't require storage, it lies idle, but with VMware or any kind of virtualization, you can utilize the full storage."
"Some of the most valuable features are: the ability to Snapshot so that when we do updates we have a layer of protection for simplified rollback; the replication that we can leverage for data center failures and data center downtime; the ease of migrating workloads from physical device to physical device for maintenance that we have to do on physical servers."
"We can slide in new resources without any impact. We can do maintenance on our clusters without any impact to applications, and we have the flexibility of migrating those workloads to other data centers, when required, in the case of data center downtime."
"The most useful features are ESXi, DRS, Auto Deploy, and the Lifecycle Manager."
"It is easy to manage the solution. It is scalable and very stable."
"The main problem with Citrix Hypervisor is getting readily available backup solutions for it. It would be wonderful if Hypervisor were better integrated with third-party backup solutions."
"The solution is only in English. It would be ideal if it was in Portuguese."
"There are several areas that need improvement including the stability of the networking stack and networking management."
"Network management needs improvement because it is not very stable."
"The manageability of the solution needs improvement. It's an extremely bad product to handle."
"I find that the features in Citrix Hypervisor are not as rich as with VMware. It would be a benefit if they had some of the other features VMware has, such as the ability to expand a drive on the fly. You do not have to take down the machine to do it but in Citrix you do."
"The solution is too expensive and people are kind of moving away from Citrix. It's starting to become a problem. It is a primary reason that while we are rebuilding we're going to seek out open-source solutions."
"The USB support for the virtual server needs improvement."
"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."
"Two improvements that I would like to see are higher resolution console modes for guests and easier switching between consoles."
"Get the HTML5 client to 100% parity to replace the Flash client."
"It would be great if VMware could have a consolidated way of delivering this as software rather than pieces and several add-ons so that you could enjoy the product in its entirety."
"An improvement could be allowing a "dark mode" for the interface. I think the HTML5 client is a little bit hard to read. It's all white. It's a little bit bright on the eyes. A lot of us IT guys view in the dark."
"There is definitely room for improvement and that improvement should be in the licensing and the simplicity of procuring additional licenses or additional VMware products. Right now, it's very complex."
"The monitoring is not good in vSphere, many times you have latency or you cannot find what you want. The events should be improved."
"Sometimes it's impossible to prevent problems from happening. With vSphere, you never know where the problem is going to come from, but you will always know that there is a problem. This is the problem."

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
