Avi Load Balancer allows upto 5 NSX-T clouds to be created.
Each NSX-T cloud can be either created for the same NSX-T manager or for different NSX-T managers. If different NSX-T managers are pointing to the same vCenter, then only one SE image per vCenter will be created.
If there are multiple NSX-T managers pointing to respective different vCenters then the SE image will be created in the respective content libraries.
The cleanup of the SE image happens only after the last NSX-T cloud pointing to the SE image is removed.
The NSX-T cloud(s) thus created can be used to create a virtual service.
A single cloud does not support both VLAN-backed and Overlay-backed networking for data plane connectivity. To use both types of networks, create separate clouds for VLAN and Overlay networks.
