    The free version is a boon for small businesses that want to have a hypervisor but not the headaches of using something that requires licensing. It is more than adequate to compete with the lesser versions of Hyper-V or VMware. Any small business that wants to lessen its hardware footprint could benefit from this product. If you are a medium or large business it is also a nice addition to the cupboard if you already use other Citrix products and are familiar with the Citrix support process. Shops that are fully committed to VMWare or MS Hyper-V should probably avoid this as it would just act to dilute your system and add unneeded complexity. Citrix Hypervisor is not most common Hardware Hypervisor on the market but it is more than competent for most Enterprise Deployments.

    It's really well suited if you are looking to implement your own private cloud for an affordable price. Definitely, the best choice if you can't afford to pay for more expensive services and tools like VMware which require pricey licenses. Having Ubuntu OpenStack open source makes it even better for the community. If you don't know how to manage your own infrastructure well or don't have the capacity, you would be better off using some other service.

    Pros

    Citrix

    • Resource Monitoring is a good and I am able to monitor my entire infrastructure whether I'm using my iPhone remotely or while on any company-issued laptop to ensure our services run at peak efficiency.
    • CLI - the command line is not hard to use. It can take a little time to get used to the commands but once you have them down managing the environment from the GUI or CLI is pretty easy.
    • Backups are very easy to start and manage with XenCenter or XoA. Keeping business DR scenarios achievable.

    • Flexibility for deploying and managing virtual machines.
    • Full fledged documentation for self learners within organization.
    • Great that it's fully an open source offering. Hence light on pockets.

    Cons

    Citrix

    • Adding or presenting additional storage to the host can often be a task that is far more involved than competitive products.
    • The product can require reboots more frequently than competitors due to the DOM kernel getting "hung up".
    • Sometimes when a virtual machine is deleted it still leaves behind orphaned vdisks.
    • Recovering from the loss of a host can sometimes cause virtual machines to require lengthy command prompt scripting to fix so they can be powered back on from another host.

    • High availability can be made better.
    • GUI of Horizon can be extended with almost all features like in CLI.
    • Long term support (LTS) can be improved, which pulls more and more customers.

      With the knowledge and usage of solutions from VMware and Microsoft offering more compelling cloud integrated options it makes it more compelling in many environments which I consult. XenServer is a good product and fits the bill in many smaller environments but as clients look to the cloud or a hybrid cloud it can in some cases make it a bit more difficult.

      Usability

      Citrix

      XenServer is quite usable due to the simplicity the management and installation provide for an administrator. The console for management is very intuitive and can easily be installed on any Windows operating system. There is a relatively simple web console that can be implemented as well that enhances the usability to provide service to non-administrators.

      Reliability and Availability

      Citrix

      It's been a little problematic in the past at larger VDI deployments requiring a bit more care and feeding than other vendors. But the latest releases (6.5.x) have brought about huge improvements in the stability and availability.

      Performance

      Citrix

      When running like a top XenServer is a fantastic hypervisor. There is relatively low overhead on the Dom0 so workloads get the most of the resources.

      In-Person Training

      Citrix

      Part of a training for certification to become a trainer for Citrix included an in-person training with a Master CCI. The XenServer training at this time was pretty simplified due to the product primarily being installed however you did have to work with it and mildly configure the system.

      Online Training

      Citrix

      Haven't given it a real go with any online training however there are some options out there. I have taught a course following Citrix material for XenDesktop which leverages XenServer and it is pre-built so not the best for XenServer specifically for installation but configuration is mildly touched on

      Ensure you review the HCL (hardware compatibility list) and reach out to the hardware vendors to ensure they support the platform and in case they have documentation that can be followed for the implementation. Also ensure the prerequisites are completed prior to implementation so that as few unexpected delays occur as you can control.

      Alternatives Considered

      Citrix

      VMware seems to be the standard and is more widely accepted. However, Citrix Hypervisor, is easily learned and cheaper. We have also used VirtualBox to offer up ideas for other free products. VirtualBox seems to be easier for end users who just want simple VMs and not necessarily entire environments. Citrix is good for environment virtualization.

      Everybody knows VMWare which is the world's number one in data center infrastructure management. OpenStack is lot lot less expensive but doesn't offer all the functionalities you have with VMWare especially for High Availability and load balancing. You should go for OpenStack if you need an easy to use solution without the need for external consultants. If you don't have the capacity to manage your own infrastructure you had better go for VMWare.

      Scalability

      Citrix

      The servers latest versions have made massive improvements to scalability. But from past experience there have been issues when running workloads for extended periods of time without reboot on the hosts. I would need to run similar workloads on the 6.5 release which has changed much of the bottlenecks or issues so I'd imagine its far more capable now, Perhaps able to stand near the best in the market.

      Return on Investment

      Citrix

      • Xenserver is easy to learn. We paid for support only for installation and deployment in the first three years, and now our team has the knowledge to solve most problems.
      • Low CAPEX if you have a team that uses open source software day by day.
      • But paid support is necessary to solve critical problems. The open source community is not enough. Actually, we have difficulty solving some bugs without paying for support.
      • Medium OPEX if you have a team that uses open source software day by day.

      • Way cheaper than other services considered.
      • More control over our own infrastructure.
      • Self healing feature is great.
      • No negatives - ROI is high.
