This edition is designed for small companies with up to 25 users and 50 devices. Just like its predecessor, Windows Server 2016 Essentials, the 2019 edition allows for integration with Azure Site Recovery services. This feature is meant to help you maintain business continuity in the event of a hardware or other failure, when your virtual machine (VM) or its host goes down.

This functionality enables you to replicate the VMs in real-time mode to a backup repository in Azure. If a disaster strikes, you can failover to the replica and resume your business-critical operations.

The 2019 Essentials edition also makes it possible to integrate with Azure Virtual network. Moving an organization’s resources to the cloud can be a complicated issue. The right way is to allow enough time for this process and perform it step by step. Windows Server 2019 Essentials, in turn, makes the resources and processes that are running in Azure look as if they are located on your local network. This allows organizations to seamlessly move their resources to the cloud.
