The Veeam Cloud Connect infrastructure configured at the SP side is hidden from tenants. Tenants know only about cloud repositories and/or cloud hosts and can work with them as with locally deployed backup repositories and target hosts. Veeam backup servers on tenants’ side do not communicate with cloud repositories and cloud hosts directly. Data communication and transfer in the cloud is carried out via cloud gateways.
The cloud gateway is a network appliance that resides on the SP side. The cloud gateway acts as communication point in the cloud: it routes commands and traffic between the SP, tenants and cloud repository.
The cloud gateway is a Microsoft Windows server running the Cloud Gateway Service — a Microsoft Windows service responsible for establishing a connection between the SP Veeam backup server, tenants’ Veeam backup servers and cloud repository.
To deploy a cloud gateway, the SP must assign the cloud gateway role to a necessary server in the SP backup infrastructure. The SP can configure a dedicated cloud gateway or install this role on the SP Veeam backup server. If traffic between the SP and tenants is significant, it is recommended that the SP deploys a dedicated cloud gateway to reduce the workload on the SP Veeam backup server.
The server performing the role of a cloud gateway must meet the following requirements:
The cloud gateway can be a physical or virtual machine.
The cloud gateway must run Microsoft Windows OS
