Software-defined networking: SDN is a short form of Software Defined Networking. It is a popular Server Windows 2019 Datacenter feature that distributes data and workloads on different locations and server networks. You can use some new features on SDN, including decrypted networks, Firewall auditing, virtual networking peering, and Egress metering. Virtual network peering helps to connect two virtual networks without any interruption. Encrypted networks let you encrypt the Virtual network traffic among all virtual machines. While this function works, you have seen the option “Encryption enabled”  

Storage Space Direct: Storage spaces direct works as a solution for software-defined storage and lets you divide and share the storage resources among the converged and hyper-converged IT infrastructure. You can face a lot of improvement features on the new update, like Native support for persistent memory, Windows admin center, performance history, Drive latency outlier detection, and more productive features. The build-in history helps you measure the performance of memory, network, storage, and server components. Besides, Windows Admin Center organizes the Storage space directly with an inbuilt dashboard. You can easily use the open, close, and create some easy clicks on the dashboard. 

Network Controller: Network Controller is the foundation of software-defined networking. It is an automatic method that plays a scalable role on the server. Besides, the network controller monitors, configures, manages, and troubleshoots the virtual network infrastructure. Also, the network controller helps a lot to determine all the devices connected to the network and services. Furthermore, you get a variety of new features under the network controller features, including virtual network management, Firewall management, Software load balance management, Gateway management, and Virtual appliance chaining. You can use a network controller to manage virtual networks, firewalls, software load balancers, etc. 

Unlimited Container: A container is a group of application packs and technology on the Windows server 2019 Datacenter that help run different operating systems applications such as Windows and Linux. You can run different OS-based applications separately on the Datacenter edition of Windows Server 2019. Besides, you can use native applications and any programming language on the server container. The container works both on-premises and cloud base. The whole process of the container is also called the container ecosystem. You get unlimited containers on Datacenter editions of the server.

Host Guardian Hyper-V Support: Host Guardian is the solution that oversure the HYper-V host by allowing only trusted virtual machines to run on them. The feature is run by combining different technologies like active directory, Trusted Platform Module(TPM), and virtualization-based security. The Hyper-V-supported feature is useful for detecting untrusted actions like public and hybrid clouds. The new Windows server Host Guardian service now runs on the Hyper-V Network Encryption. Besides, the Host Guardian Service supports Virtual trusted platform modules that protect data and configuration.
