The supplied cloud proxy provides an OVA that contains the credentials and protocols needed to create a connection between a cloud account in VMware Cloud Assembly and an associated on-premises endpoint in vCenter.

vCenter-based cloud accounts require that a cloud proxy be deployed to a source vCenter for data collection and communication between the cloud account and an on-premises endpoint.

These cloud account types include vCenter Server, NSX-V, NSX-T, and VMware Cloud on AWS.

Amazon Web Services and Microsoft Azure cloud accounts do not require the cloud proxy.
