The main features that we are using are active directory, domain, and DNS.
They can simplify the utilization and control of the system when you have a lot of setups. They provided something called Windows Center or Control Center in version 2019. It's a free tool that comes with the Windows Server. You can install it on your desktop and use it.
This tool simplifies the control and monitoring of all servers. If I have 200 servers, I don't need to log in to each one to configure it. I can manage them from this tool. However, this tool needs quite a lot of improvements. It's difficult to use, and they need to improve it.
I have been using this solution since 1990. Currently, we are using the latest version. We have the cloud and on-premises deployments.
The initial setup was straightforward. It took around 15 minutes. Usually, on the server, we don't do the physical installation. When we install initially, we install an image. You just create an image, and that's it. After that, we don't need to do an installation.
There are only two options in the market: Windows and Linux. It depends on your application. If you have an application that requires Windows, you go with Windows Server. Otherwise, you go for Linux. There are not enough choices to choose from and decide.
They had an issue in version 2016 related to the slowness of update management, but they already solved it in version 2019. It was impacting batch management. The time that Windows required was a lot, but it was fixed in version 2019. That was the only issue we faced in Windows Server. Other than that, it's fine.
I would advise on the version, not on the solution itself, that is, whether to use Windows Server or not. If Windows Server is a required solution, you have to take it. It's not an option. However, I would advise to not use version 2016.
I would rate Windows Server a ten out of ten. If your application is required on Windows, it's not comparable to any other solution. If an application can work with Windows or Linux, for sure, I'm going with Linux.
