When deploying an on-premises resource location for a Citrix Cloud-managed Site, a Citrix Administrator should configure the Virtual Delivery Agent…

In a Citrix Cloud architecture, the control plane (including Delivery Controllers) resides in Citrix Cloud, while workload resources (VDAs) are in a resource location (e.g., on-premises). The Citrix Cloud Connector is a component installed in the on-premises resource location that acts as a secure communication channel to the control plane. For a VDA to register with the Site, it must be configured with the addresses of the Cloud Connectors within its local resource location. The VDA communicates with these on-premises Cloud Connectors, which then proxy the registration and all subsequent communication to the Delivery Controllers in Citrix Cloud.

A. Delivery Controller, Citrix Cloud: VDAs in a resource location do not communicate directly with the Delivery Controllers in Citrix Cloud. All communication is proxied through the Cloud Connectors.

B. Cloud Connector, Citrix Cloud: The Cloud Connector component is, by design, installed within the customer's resource location (on-premises or public cloud), not within the Citrix Cloud infrastructure itself.

C. Delivery Controller, on-premises: This describes a traditional, customer-managed Citrix Virtual Apps and Desktops deployment. In a Citrix Cloud-managed Site, the Delivery Controllers are hosted in Citrix Cloud.

1. Citrix Product Documentation, Citrix DaaS, "VDA registration with Cloud Connectors": "To register with Citrix Cloud, the VDA must know the address of at least one Cloud Connector in the resource location... During VDA installation, you can specify the addresses of Cloud Connectors." This confirms VDAs are configured to communicate with Cloud Connectors in the resource location.

2. Citrix Tech Zone, Reference Architecture, "Citrix DaaS": In the "Resource Location" section, the architectural diagrams consistently show VDAs communicating with Cloud Connectors within the same resource location boundary. The document states, "The Cloud Connector authenticates and encrypts all communication between Citrix Cloud and the resource location." This highlights the Connector's role as the local communication proxy.

3. Citrix Product Documentation, Citrix DaaS, "Install VDAs", Step 7. Controllers: "Select Let the Machine Creation Services do it or Do it manually. If you select Do it manually, enter the FQDN of a Cloud Connector." This installation step explicitly requires the address of the on-premises Cloud Connector for VDA registration.
