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 compatibility of the solution is its most valuable feature. It's compatible on almost every cloud these days."
"This solution allows the end users to clone, start, stop, or remotely control their VMs."
"The feature I find most valuable, is its performance"
"The initial setup is easy."
"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."
"Citrix is easy to use and is stable."
"What I like the most is the support of the GPU Graphics and the VM Live migration."
"Ability to move your virtual machines from one host to another."
"It is the number one virtualization-layer platform available, and a lot of people trust it."
"From the interface, you see how much CPU utilization and RAM utilization that each one of those hosts is giving you. You can tell ahead of time when you need to start expanding the environment. And with VMotion, you expand the environment and then let DRS have at it and walk away."
"The ability to monitor resource utilization."
"Technical support is very good. They are very helpful."
"The most valuable features for me are a very easily scalable infrastructure. I can have a couple of hosts to do basic workloads. I can have a lot of hosts to do a lot of workloads. vSAN integrates my storage so I don't need an external storage SAN. I love having everything integrated in the same UI. The new HTML5 interface doesn't require any plugins anymore and it's super-fast."
"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."
"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."
"Most valuable features are quick provisioning, High Availability, and DRS for balancing workload."
"The licensing costs are too high on the solution. They should work to make the costs more reasonable."
"The solution should be more flexible and allow for greater customization."
"I would like the possibility of updating the hypervisor by applying security patches."
"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 built-in networking features are a little limited."
"There are several areas that need improvement including the stability of the networking stack and networking management."
"I think the technical support could be better."
"Overall, I can't think of a feature that is lacking. We've been pretty satisfied overall."
"There is still room for improvement with the HTML5 Web Client. They are working on it, as I can see on their blog. However, there is still room for improvement in the newer features that they can push into it."
"I would like to see support for endpoint virtualization."
"The performance of the solution could be better and there could be an extra level of security."
"Technical support is not that great. It is too slow."
"We stopped using a lot of cloud services. However, I see that VMware has integrated with Amazon Cloud. We will now to have to move everything to the cloud."
"The implementation of VMware vSphere is easy. For integration companies, it's easy, the final client cannot do it alone but for an implementor it's easy."
"I would like to see DRS for the GPU machines."
"Although vSphere is a nearly perfect product, it does need a little improvement. Datacenter and Cluster structure should be mixed so that the management of clusters would be easier."
Citrix Hypervisor is ranked 8th in Server Virtualization Software with 45 reviews while VMware vSphere is ranked 2nd in Server Virtualization Software with 443 reviews. Citrix Hypervisor is rated 8.2, while VMware vSphere is rated 8.8. The top reviewer of Citrix Hypervisor writes "Good features, fair pricing, and excellent reliability". On the other hand, the top reviewer of VMware vSphere writes "Allows for easy management of snapshots for virtual machines and good web console ". Citrix Hypervisor is most compared with Proxmox VE, Hyper-V, Oracle VM VirtualBox, KVM and Nutanix AHV Virtualization, whereas VMware vSphere is most compared with Hyper-V, Proxmox VE, VMware Workstation, Oracle VM and IBM PowerVM.

We monitor all Server Virtualization Software reviews to prevent fraudulent reviews and keep review quality high. We do not post reviews by company employees or direct competitors. We validate each review for authenticity via cross-reference with LinkedIn, and personal follow-up with the reviewer when necessary.
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 http://www.citrix.com/products.html?posit=glnav 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
