We used Windows Server. It has not been very painful but when I compare it with RHEL the patching process was lengthy. We also ran into occasional performance issues that were not very straight forward to diagnose.
Chose Red Hat Enterprise Linux (RHEL)
Windows Server's are perfect competition for RHEL as many people use Windows Servers for deploying their applications. Windows provides good GUI but it lacks in many aspects in which RHEL is a win-win. As earlier mentioned, the performance of RHEL is unbeatable cannot be …

While many enterprise applications offer Windows Server support, I never really seriously considered it for our application, as Windows simply Blue Screens too often for serving a business critical application. Instead, I took a look at Red Hat's upstream distro, CentOS. Had …
Chose Red Hat Enterprise Linux (RHEL)
Windows Server can take a long time to patch, waiting for the patch to install, then waiting to apply, after the OS is rebooted it can also take additional time to apply the update. Often times Windows Server patches can fail, leading to long troubleshooting times and …
Chose Red Hat Enterprise Linux (RHEL)
We chose RHEL over other Linux distributions because of its enterprise support, stability, and security features. Compared to alternatives like Ubuntu or CentOS, RHEL offers more extended lifecycle support.

Beats them all for reliability, security, ease of use and setup, as well as patching. It has fewer support problems and is easily serviced. Support is easy to find and quite helpful. Windows crashed all the time and Azure was at times spotty.
Chose Red Hat Enterprise Linux (RHEL)
RHEL is very different than Windows, but in terms of just a simple operating system, RHEL is much more lightweight than Windows and in many cases runs more efficiently than Windows. Given the choice between the two, some application are preferable on RHEL, like Apache or …

Chose Red Hat Enterprise Linux (RHEL)
Each of the different flavors of Linux have their positives and negatives but ultimately for the projects that I chose Red Hat Enterprise Linux was due for the need of online and phone support just in case something came up and we could not solve it on our own. This happens …
Chose Red Hat Enterprise Linux (RHEL)
Linux has improved features and utilities over Unix. Scalability and ease of configuration management an improvement over Windows.
Windows Server
Chose Windows Server
I find Microsoft Windows Server is a much easier OS to deploy and administer. It does require more resources to run, requires more security updates and overall has a larger footprint. Rebooting the Windows Server takes a much longer time than RHEL for example. An administration …
Chose Windows Server
Windows Server is more cost-effective and skills are easier to find to support the products. The deployment and management of the product can be automated with Microsoft SCCM. In my opinion, Linux seems to be more secured but takes more time and effort to learn than Windows …
Chose Windows Server
These are just very different products. They can all have the same functionality but the specific product knowledge with Linux is much higher. This slows down troubleshooting and can leave you with limited options for high end support. There are absolutely good use cases for …

We have various servers or appliances that run on various flavors of Linux that do their jobs well, but we configure and manage them very lightly at the OS level. Most of the admin on these devices is sone inside the applications themselves. We don't shy away from new …
Chose Windows Server
For our purposes it came down to picking between Windows and Linux and at the end of the day we picked both. We use Windows for 80% of our server needs to run our Web, File, Print, DHCP, Internal DNS, Active Directory, SQL, Web and other windows based servers. We use linux …
Chose Windows Server
Windows Server is the only one that has an upfront cost for licensing before hardware is considered. Windows Server is generally better suited for multi-faceted approaches; however, for just backups, TrueNAS and Synology are cheaper and just as good. For standalone services …
Chose Windows Server
Windows runs some applications better and is easier for junior admins and non-technical users to administer and get started with. It obviously does not run everything better, so other operating systems are preferable in some situations. Compared to OSs like RHEL, they both have …
Chose Windows Server
When using a Linux system such as CentOS in a server situation to get certain features like Windows Server, it can take a lot of jerry-rigging and configuration to get the same results that can be set up with Windows Server in a lower amount of time.
Chose Windows Server
Windows Server is the most Enterprise/Business server around, easy to deploy and configure and to co-exist with other servers. Most if not every other server technology is usually very good for a very specific purpose but fail in the coexistence and integration when compared …
Chose Windows Server
A lot more industry-standard application support. Ease of use. Security patched happen more often.

Red Hat
Red Hat Enterprise Linux (RHEL) is best suited for its stability, fast reboot time, and minimal resource requirements which reduce overall cost. The patch time for Red Hat Enterprise Linux (RHEL) is also extremely fast which benefits application up time. For environments or applications that require many changes, for a Red Hat Enterprise Linux (RHEL) support person that is not well trained and experienced in Red Hat Enterprise Linux (RHEL), this can be challenging.

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.

Pros
Red Hat
  • Virtualization, like the operating system level task. I see this product is very good and it blends very well with the middleware components like all the JBoss and other things. And other than that, either you install it or a virtual machine or physical servers, it works seamlessly anywhere. And if you want to go further, like Red Hat OpenShift or those things also work very nice with it.

  • Backup of workstations & itself - reliably, consistently, with Bare-Metal Restore and deduplication
  • File management and Security on a per file/folder/user basis is simple and fully done through an easy GUI
  • DNS, DHCP server functions are easy to configure using the built-in GUI

  • 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
Red Hat
  • In the LEAP process. The upgrading process, which I'm hearing, like I said it before, prior that I was on rail seven, eight, and nine. Trying to get all of that to rail nine and stay current. The LEAP process from seven to eight is a little bit less than desired. I've talked to some people that from once you get on eight from eight to nine to nine to 10 is a breeze. So I'm looking forward to that.

  • 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.

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.

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.

The Red Hat Enterprise Linux (RHEL) distro is the simplest enterprise version of Red Hat that is enterprise supported and when you deploy as many VMs as we do, it is vital to have that enterprise support. On top of the enterprise support, having access to a commercially supported backbone for updates and upgrades is a huge plus.

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.

Red Hat support has really come a long way in the last 10 years, The general support is great, and the specialized product support teams are extremely knowledgeable about their specific products. Response time is good and you never need to escalate.

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.

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.

Alternatives Considered
Red Hat
So we in our company have used Ubuntu as well. Sometimes we have to use that because a certain application installer requires that we use that operating system, but we really don't prefer it just because it doesn't come with the same Add-on features that make Red Hat Enterprise Linux (RHEL) really great, like Red Hat Insights or Red Hat satellite, things like that. They come package with it. So that would be the main one. I've also used things like FreeBSD, but I think that's just too old at this point to care.

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.
