VMware is an established virtualization platform that is easy to set up and works with most operating systems. It is continuously improved by its large development resources at EMC. It has strong relationships and integrations that enhance its networking and storage capabilities. Citrix is also easy to set up and has established upgrade processes, but may have higher costs than VMware for large organizations. It supports Nvidia GPUs and has easier network bonding than VMware. Hyper-V is easy to install but lacks the maturity of VMware and Citrix. It does not support all operating systems and has issues with network and cluster configurations.

1. VMWARE
- Easier to setup, established product, works with most OSs
- Is owned by EMC (1 storage vendor) and has plenty of
development resources
- Constantly improves, has an established upgrade process
- Just works, seems to be very flexible and is ready for
production environment
- Has relationships with many organizations where they
continue to improve (features and benefits) especially when
it comes to networking (virtual networking - able to control
the packets ability to traverse the network using an
application)
- Storage virtualization has improved along with giving
vendors the ability to develop API's to work with their
solution
- Has integrated with Powershell to allow for automated VM
management
- Does not work with Nvidia GPUs, but they are in the works
- Faster ESXi server setup, integrated LDAP (AD) tools, VC
management interface, very easy to install

2. CITRIX
- Easy to setup, continues to establish capabilities, works
with most OSs
- Found that it is easy to setup an ISO file from a CIFS share,
no need to upload into datastore (like that of Vmware)
- Has an established upgrade policy
- Complex powershell automation configuration
- Faster VDI implementation, but for large organizations,
costs seem to be the an issue because of the much needed
hardware
- Works with Nvidia GPUs
- Easier Network bonding and implementation
- Status view of the XenServer gives real-time stats, none
really found on Vmware ESXi server (they have the
capability found on VMware Operations Manager but not
on the ESXi server itself)

3. HYPER-V
- Easy to install and configure
- Not really an established technology, found some glitches
with Windows 2008 but they have worked out a lot of the
problems with 2012
- Does not work with all OS, had problems with Linux and
Unix (Mint, Solaris, Xubuntu, etc)
- Cluster configuration, complex
- Network configuration needs more development work,
they need to work at bonding the NICs
- Cluster configuration only works with ISCSI protocols
