    In the scheme of the real world, Citrix Hypervisor is used much less than the other two main competing products; MS Hyper-V and VMWare vSphere. So, choosing Citrix Hypervisor for your organization comes down to whether you are comfortable going with a lesser-used product. All …

    Windows Server and Active Directory is very robust and stable, it has been a staple in every IT environment I have worked in during my career. Junior to Intermediate admins can learn Windows Server easily, the user interfaces make administration tasks very easy as well as the documentation available through a vast amount of resources. There are other Operating Systems available with no GUI which has a smaller attack surface, faster update installation and reboot time. Windows Server does have the ability to remove the desktop experience, however it is not something I have had experience with and I believe most administrators choose not to remove it.

    It can be really helpful & useful if we are using Citrix Hypervisor with other provisioning tools. Here are some specific scenarios where Citrix Hypervisor (formerly Citrix XenServer) is well-suited: Server Consolidation, Virtual Desktops, Disaster Recovery, Development & Testing Environments. On the other hand, there are some scenarios where Citrix Hypervisor may be less appropriate: Small-scale Deployments, Highly Heterogeneous Environments, and Limited Virtualization Requirements.

    • Citrix hypervisor does price very well for small organizations. It is free.
    • Since this product is open source it does not have any type of vendor lockdown issues.
    • Allows live migration of VM's so you can keep systems up and running when changes are needed to the hardware in the background.
    • The GUI management tools are quite easy to learn.
    • Has Snapshot capability which is a great way to protect against malware as well as do risk-free upgrades.

    Cons
    Microsoft
    • Microsoft needs to minimize the update frequency by making the product more secure. It can become very exhausting trying to keep updated if you don't have a dedicated support team. It can become challenging where the business is unable to allow downtime for reboots as part of the update process.
    • Prone to security and audit vulnerabilities.
    • The operating system needs more CPU and memory resources compared to other options such as Linux.
    • Understanding the licensing model can be abit confusing.
    • Comes with a standard firewall, but not the most secured one available. Would suggest using a more secured firewall as part of your antivirus software.
    • Due to the number of vulnerabilities and the operating system being a target for hackers, anti-virus software is a must.

    • 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.

    I've carefully reviewed the servers and services currently running on Windows Server 2012, and given the opportunity would renew them as is going forward. There are two systems I currently have in place, one is a very large Linux implementation for a large ecommerce site, and one is a very large backup solution front ended by FTP servers running Linux. Neither are well suited for Windows, but the overall network infrastructure is and will be Windows Server for the foreseeable future.

    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
    Microsoft
    Anyone new to IT could easily use the familiar Desktop Experience (GUI) version because we all know how to use Windows, whether a client or server version. Once an IT user is more comfortable with the operating system, they can move on to the Core version, which is the way to go in almost all situations.

    XenServer is a good product in its use and probably free if you have the right Citrix licenses already. However, it does require specific knowledge to manage, which makes it harder to manage if you don't have that knowledge in house.

    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.

    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.

    Support Rating

    Microsoft's support is hugely wide-ranging from articles online to having to contact them directly for the more serious issues. In recent years when I have contacted them directly, I have found the support o be excellent as I have found myself connected to very knowledgeable people in the field in which I needed the support. The online support available is vast and I tend to find most of the time that there is always someone out there who has had the same issue as me in the past and knows something about how to resolve it! This is the advantage of using industry standard and long-established systems such as Windows Server.

    The staff I've worked with are very knowledgeable or able to get a very well articulated and capable support team member on the phone or helping them if necessary and they always want to ensure the best experience possible for you on the platform. The ability for the support team to reach out to hardware vendors for assistance is a nice plus too.

    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.

    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

    Make sure that you have detailed processes in place for every server instance you plan to install/upgrade, if possible get the base OS loaded and Windows Updates applied ahead of time, and if using a VM take a snapshot prior to installing each role, as well as along the way.

    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.

    They are different experiences, and while the other solutions offer enterprise-grade stability and, in some cases, address Windows server shortcomings (such as patching), they all do the trick, but the other solutions require a deeper technical background/configuration of items at the command line, which some people are not fully comfortable with.

    Feature for feature they are neck and neck. I have used Hyper-V 2012 and 2016, VMware ESXi and XenServer evenly. XenServer is a fast install, good documentation, with enterprise features out the box that compare or exceed what VMWare offered with a higher cost of entry.

    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.

    • 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.
