 | **Component** | **Requirement** | **Details** |
 | --- | --- | --- |
 | **Azure** | An Azure subscription and an Azure network. | Replicated data from on-premises physical machines is stored in Azure managed disks. Azure VMs are created with the replicated data when you run a failover from on-premises to Azure. The Azure VMs connect to the Azure virtual network when they're created. |
+| **Configuration server machine** | A single on-premises machine. We recommend that you run it as a VMware VM that can be deployed from a downloaded OVF template.<br/><br/> The machine runs all on-premises Site Recovery components, which include the configuration server, process server, and master target server. | **Configuration server**: Coordinates communications between on-premises and Azure, and manages data replication.<br/><br/> **Process server**: Installed by default on the configuration server. It receives replication data; optimizes it with caching, compression, and encryption; and sends it to Azure Storage. The process server also installs Azure Site Recovery Mobility Service on VMs you want to replicate, and performs automatic discovery of on-premises machines. As your deployment grows, you can add additional, separate process servers to handle larger volumes of replication traffic.<br/><br/> **Master target server**: Installed by default on the configuration server. It handles replication data during failback from Azure. For large deployments, you can add an additional, separate master target server for failback. |
 | **Process server** | Installed by default together with the configuration server. | Acts as a replication gateway. Receives replication data, optimizes it with caching, compression, and encryption, and sends it to Azure storage.<br/><br/> The process server also installs the Mobility service on servers you want to replicate.<br/><br/> As your deployment grows, you can add additional, separate process servers to handle larger volumes of replication traffic. |
 | **Master target server** | Installed by default together with the configuration server. | Handles replication data during fail back from Azure.<br/><br/> For large deployments, you can add an additional, separate master target server for failback. |
 | **Replicated servers** | The Mobility service is installed on each server you replicate. | We recommend you allow automatic installation from the process server. Or, you can install the service manually, or use an automated deployment method such as Configuration Manager. |
