Windows Server 2019: Comparing Server Core & Desktop Experience (GUI)

Windows Server 2019: Comparing Server Core & Desktop Experience (GUI)

Does a modern business survive with only a cloud support for all of its activities? I bet not. Perhaps you need a more solid super computer that can help you on all of your duties like a server. But which one do you get? A Windows Server Core or a Windows Server with Desktop Experience?

Let’s find out in this blog as we discuss the general features of each server type from Microsoft.

What are servers?

Like I mentioned, a server is like having a super computer that’s more powerful than your average PC. It handles duties carried on in a network of computers so it needs to have high capacity and specifications for it to handle all of those tasks. Not only is it storing and sharing data across your business, so it needs to be capable of running multi-user applications in parallel.

Servers play a crucial role in any commercial setup because as your business expands, the things you do on your computer also grow. When it does, it can be harder to handle digital activities. This leads you to having the need to score a server where your resources can be stored, organized and shared from your PC to hardware devices like printers.

Your server will sit between the router and the rest of your network. It will provide support to digital activities and give your office a secure access to key resources. The good news is, it can be utilized by members of the network anywhere, anytime.

The benefits of having a server

The biggest benefit of having a server of your own is probably keeping everything centralized gives you more control over how your business – including its data – is handled. It’s easier to keep track of files and helps prevent data fragmentation, which happens when people work on separate, multiple copies of the same file. Servers also simplify the process of sharing tools, devices, settings and files – particularly if you’re spread over multiple locations.

Servers are designed for remote administration, so configuration and troubleshooting can often be handled without having to physically access the server or an employee’s computer. And speaking of employees, servers excel in multi-user setups, whereby each person has their own customized access to your business’s resources, ensuring they have what they need and no access to what they don’t. Multi-user setups are also handy if you need to share desks or office space – users simply sign into a computer to access their personalized setup, including apps and data.

Servers are also hugely flexible. As your business grows, they can be reconfigured to add extra functionality, such as customer relationship management software or a centralized email platform.

What type of server hardware should I get?

Servers can be cloud-based or physical. Here, I will cite the types of physical servers.

1. If you’re just starting out with a small business, then a tower server is a solid choice. This looks like a cabinet and is a self-contained server with everything housed in a single tower case, which requires no dedicated server room and can even be stashed under a desk if space is tight. Tower servers are particularly suited to smaller businesses with fewer than 25 clients or workstations.

this is a tower server2. The other principal type is a rack server. This is a more flexible – but more complicated – setup, whereby you stack multiple servers together in special racks, enabling you to build customized setups with different servers handling specific tasks if required. Rack servers are easy to upgrade and expand as circumstances demand.

this is how a rack server looks likeThe racks also accommodate all other required hardware, from storage to security and network appliances. Rack servers will usually require their own dedicated room and are best for larger businesses or those with a focus on information technology.

After deciding on the server hardware, you’re left with one more decision before you can enjoy solid support for your whole computer network – scoring a server OS.

A server operating system, also called a server OS, is an operating system specifically designed to run on servers, which are specialized computers that operate within a client/server architecture to serve the requests of client computers on the network.

Among the few server OS available in the market, Windows Server remains to be the most popular.

Microsoft Windows Server – Leading the Server OS

what is the difference between server core and server desktop experience guiMicrosoft’s Windows server is just one of the most preferred products to activate a server. Its latest version Windows Server 2019 is available in two forms: Server Core and Desktop Experience (GUI) .This article focuses on key aspects relating to those forms: Server Core and Desktop Experience. Both forms are available for either product edition:

  • Windows Server 2019 Standard
  • Windows Server 2019 Datacenter

But there are more products that use servers. Let’s list them down and see which servers they use:

  • Windows Server 2019 Standard (Server Core or Desktop Experience)
  • Windows Server 2019 Datacenter (Server Core or Desktop Experience)
  • Windows Server 2019 Essentials (Desktop Experience only)
  • Hyper-V Server 2019 — (Server Core only)

It can get confusing but there are requirements in Windows Server Essential that doesn’t fit Server Core and that goes the same for Hyper-V Server which works only with Hyper-V.

Going to the 2 server types, let’s now look into the experience of using Server Core and Server with Desktop Experience (GUI)

Server Core vs. Desktop GUI

To give you a quick overview, I came up with this infographics, presenting the availability of both servers for some features.

Windows Server 2019: Comparing Server Core & Desktop Experience (GUI)

  • Windows Server Desktop Experience (GUI – graphical user interface ) is the classic and well known form of Windows Server. It has been around since the iconic Windows NT. Desktop Experience obviously contains a GUI, rendering the machine comparatively user-friendly and easier to manage either remotely or locally.
  • Windows Server — Server Core, on the other hand,is a strapped down version of Windows Server. Generally speaking, it contains no GUI (but this does not always have to be the case.

Server Powered by Server Core

The classic advantages of Server Core include lower consumption of CPU, RAM and disk space. There is also less vulnerability but more resistance to cyber attack as it contains a smaller attack surface and less code. Less is installed with Server Core by default, and much can be added on a per-need basis. Some roles and functions, however, are not supported.

There are less updates and less patches which means there are also less reboots.

Server Core makes it easy to turn off Windows Update by setting updates to manual via Sconfig. And since it is designed to be managed remotely, the fact that it’s local management is complex, is less of an issue. With that said, remote management remains more complex and consuming with Server Core.

This Server OS can be looked at as more with less, i.e. less resources are consumed by the OS and more resources are available for the user and applications. However, there’s a price for that.

You will love that the Server Core can receive an “upgrade” in the shape of GUI-based tools. This allowsit to be locally managed in a user-friendly manner.

Overall, Server Core gives more resources but it also takes more hard work for managing it. In addition, some applications are not supported and cannot be installed on it, regardless. You thought that installing a PDF reader is easy? Let’s see you doing that with Server Core. Server Core is not designed to accomplish such tasks, though it would make it somewhat harder to accomplish any task.

Server with Desktop Experience (GUI)

Perhaps one of the good things with Server Core, is that it lets you appreciate Windows Desktop Experience once again. Suddenly the standard Windows GUI may be seen in a different light, as if it is less trivial or something.

Like I mentioned, Desktop Experience is the classic and well known form of Windows Server. It is much more user-friendly and easier to manage. The well known Server Manager dashboard appears upon login as in previous versions of Windows Server. Compared with Server Core command line, the dashboard is much of a relief.

The GUI of Windows Server 2019 is similar to Windows 10 version 1809 (aka Windows 2019 Enterprise LTSC). However, the default configuration and settings of Windows Server lean more toward security and privacy, in contrast with Windows 10.

Desktop Experience comes with more features and capabilities preinstalled by default. In one hand that’s great as more things are available at the palm of the and, rather than require multiple steps to accomplish.

On the other hand, this methodology also renders Desktop Experience a heavier machine, which consumes more resources, operates slower, while at the same time being more vulnerable to cyber attacks. Desktop Experience, providing more, also requires more patches and restarts.

Overall, Windows Server gives less resources but requires less maintenance and hard work. Therefore, if the prime focus is on CPU and resources utilization then Server Core takes the lead. However, that would also require the knowledge to managing Server Core as well as the required infrastructure or settings.

Limitations and Incompatibilities

Generally speaking, Windows Server with Desktop Experience can do anything that Server Core can, though Server Core is expected to perform better whichever tasks it is capable of accomplishing. The same does not hold true the other way around. Server Core lacks compatibility with variety of applications and features, thus it cannot fully substitute the good old Windows Server with Desktop Experience. Mainly, Core fails to be compatible with applications which require a GUI.

The following applications are incompatible with Server Core:

  • Microsoft Server Virtual Machine Manager 2019
  • System Center Data Protection Manager 2019
  • Sharepoint Server 2019
  • Project Server 2019

According to Microsoft, the following capabilities are not supported as well: Windows Tiff IFilter, Internet Printing Client, RAS Connection Manager Kit, Simple TCP/IP Services, TFTP Client, Windows Search Service, XPS Viewer, and much more.

Features On Demand

Windows Server 2019 Features On Demand is available for Server Core only. Generally speaking, Windows Server 2019 Features On Demand (FOD) is a pack of tools or features which Microsoft offers for free, though they are not integrated with the Windows installation. Rather, they are available as an extension, i.e. they shall be installed in separate from Windows setup.

Final Words

The decision whether to install Windows Server 2019 Core Server or Desktop Experience (GUI) must be made beforehand, as once the product is installed, it cannot be converted between Core Server and Desktop Experience.

Server Core is not as “pretty”. It is not user-friendly and not meant to be managed locally but rather from remote, via proprietary remote management solutions. Even with such tools, it requires more effort to be managed, and moreover, setting such tools might take some effort to begin with.

Setting up Windows Admin Center for instance, requires transferring the installation file to Server Core, which can be done via PowerShell on the VM host, and then executing the setup file via CMD. This is not impossible, but if you are not so familiar with such a practice, then there would be a quite learning curve. In contrast, setting up WAC on a Desktop Experience, would be something in the line of clicking the familiar next> I agree> Finish prompts.

Server Core does not support many apps, regardless. You’d probably not want to run Google Chrome on a server. In the case of Server Core, you couldn’t even if you wanted. However, you may wish to run Hyper-V manager locally, which Server Core won’t let you just as well.

On the other hand, Server Core consumes less resources and requires less updates and restarts. It is also less vulnerable. For the hard work you put into it, it returns with more availability of resources. Where exactly does the line of productivity cross, is a subjective and depends on the user and infrastructure. But for sure now you know what server OS to buy.
