Introduction
Windows Server 2019 is an operating system created by Microsoft and created to run on servers. Servers are specialized computers that usually operate within the client-server network; servers handle requests from the clients on the network. The use of a server operating system can allow other applications to run on the server’s hardware, and this can help fill different server job functions, such as a mail server or print server.
Microsoft Windows Server 2019Â is based on the popular Windows Server 2016, and aims to reduce business risk and enhance security through the multiple layers of security and protection embedded in the operating system. One of the difference from the previous versions is the addition of hyper-converged infrastructure (HCI) and Hybrid capabilities with Azure (which provides a number of cloud services like virtual computing, analytics, storage and networking).
Microsoft Windows Server 2019 is available in 3 editions, standard, datacenter and essentials. Choosing the right edition is extremely important so you don’t end up buying something which is either incapable of fulfilling your wants, or has unnecessary features which will add to your costs.
Every business has different needs and budget. Read on to know the major differences between the Windows Server 2019 Standard and Datacenter editions.
Windows Server 2019 Standard
Windows Server Standard 2019 is suitable for small and medium businesses, that does not have high virtualisation needs. This edition allows you to use up to 2 Virtual Machines with 1 Hyper-V host for each license. If you want to add 2 more virtual machines, you have to license all the cores in the server again.
Windows Server 2019 Standard enables you to modernize apps quickly, and download them faster, while enhancing the support system. However, this edition allows you to use only Windows containers, but you can use an unlimited number of such containers.
The Standard edition also lacks Host Guardian Hyper-V Support and thus does not ensure that the hoster knows about the Hyper-V hosts. Also, it does not allow you to manage the keys required to start shielded virtual machines.
This Windows Server 2019 Standard edition is also equipped with a Storage Replication; limited to 1 partnership and 1 resource group. It allows the customers to replicate a single volume of data up to 2 TB.
You can activate this edition as a guest only if you are hosted on the Datacenter edition. Also, the Standard edition lacks features like Software-defined Networking (which is responsible for enabling you to manage your network efficiently and monitor and improve its performance) and Storage Spaces Direct (responsible for creating a highly-available software-defined storage at a lower cost through the use of industry-standard servers along with local-attached drives).
Windows Server 2019 Datacenter
The Windows Server Datacenter edition offers the widest range of capabilities and features without a large number of licensing limitations. It allows you to use an unlimited number of virtual machines, with 1 Hyper-V host for each license.
This edition is suitable for businesses demanding advances storage and virtualization, and who have more demanding Information technology needs. It allows you to use all types of containers and does not set any limit to the number of containers that you can use.
The Datacenter edition is equipped with unique product features. One of them is the Host Guardian Hyper-V Support. This enables you to run a trusted software and manage the keys required to start up shielded virtual machines. This also ensures that the enterprise or hosting company is aware of the Hyper-V hosts.
The Windows Server 2019 Datacenter edition also has Storage Replica with no limits on the amount of data or number of volumes. This allows you to replicate or back up all your data for disaster recovery, and ensure smooth functioning of your website.
You can activate this edition either as a guest or as a host. This edition also has the feature of Software-defined networking, which allows you to program the network in a centrally-controlled manner. It also enables you to monitor and improve the network holistically, notwithstanding the network technology.
Another feature is Storage Spaces Direct, which gives incomparable performance and efficiency when it comes to storage of data. It uses industry-standard, highly-available servers to store your data in local-attached drives. All this comes at a price cheaper than the traditional NAS or SAN arrays.
Another advantage of the Datacenter edition is that you can virtualize an unlimited number of Windows Server instances within the physical Windows Server machine.

Super fast. some what simple. Gives you all the links of what to install plus your key. As soon as i purchased it gave me my key instantly. My key unfortunately was already claimed. So need a replacement. easy process as well to troubleshoot. Probably something they should fix in their system to not give out codes that have been used max times. Other than that, You have windows in less than 5 minutes!

The first title I purchased I was very skeptical but I needed it for school but could not afford retail price. I was blown away at the ease of use and credibility of the company, so I decided to purchase another title for business. It was the same stellar service at a very reasonable price. Thank you so much, I am a customer for a long while.
