vCloud Director Extender Components

vCloud Director Extender includes multiple components that you must install and configure in a specific order. You use the management interface of each of the vCloud Director Extender appliances - Cloud Service Setup UI at https://vCD_Extender_Cloud_Appliance_IP/ui/mgmt/ and OnPrem Setup UI at https://vCD_Extender_OnPrem_Appliance_IP/ui/mgmt - to install and configure the vCloud Director Extender software.

You use the vCloud Director Extender OVA file to deploy the vCloud Director Extender Cloud Appliance and the vCloud Director Extender On-Premise Appliance. You use the Cloud Service Setup UI and the OnPrem Setup UI to install and configure the remaining vCloud Director Extender components.

Table 1. Service Provider Components

Component	Description
vCloud Director Extender Cloud Appliance that hosts the CX Cloud Service	You deploy the vCloud Director Extender Cloud Appliance in the service provider cloud environment by using the vCloud Director Extender OVA. The vCloud Director Extender Cloud Appliance hosts the CX Cloud Service and the Cloud Service Setup UI that you use for configuring the vCloud Director Extender cloud components.
Replication Manager	You deploy the Replication Manager in the service provider cloud environment. Replication Manager manages the Replicator and is responsible for configuring the Replicator hosts and staging the replication workflow.
Replicator	Replicator, also known as the Replicator, is a replication and recovery engine used for the virtual machines migration. Runs both on-premise and on a cloud provider side and takes care of the data transfer and monitoring.
NSX (NSX Manager and NSX Edge service gateways)	NSX is the network virtualization platform used in the service provider environment. For more information, see NSX Installation Guide.

Note:

During vCloud Director Extender configuration operations, the Cloud Service Setup UI deploys a dedicated VM for each component . A vCloud Director Extender installation consists of a minimum of four VMs, including at least one Replicator host per resource vCenter Server. Depending on the load, you might add additional Replicator instances for a resource vCenter Server. For more information, see Add a New Replicator.

Table 2. Tenant Components

Component	Description
vCloud Director Extender On-Premise Appliance	The vCloud Director Extender On-Premise Appliance registers as the vCloud Director Extender plug-in to the on-premise vSphere Web Client.
Replicator	The Replicator is the replication and recovery engine used for VM migration. The Replicator runs both on-premise and on a cloud provider side and takes care of the data transfer and monitoring.
NSX (NSX Manager and NSX Edge service gateways)	NSX is an optional component for the tenant environment. If NSX is deployed in the on-premise environment, you can extend both on-premise VLAN and VxLAN networks to a cloud VxLAN network. If NSX is not deployed in the tenant environment, vCloud Director Extender deploys an NSX for vSphere Standalone Edge - Client 6.3.0 that is included in the vCloud Director Extender OVA file. For such environments, you can only extend a VLAN on-premise network to VxLAN network in the cloud.
