There's more...

There is an ACI plugin for vCenter:

The plugin allows you to manage the ACI fabric from within the vSphere web client. You can create, modify, and delete tenants, application profiles, EPGs, contracts, VRFs, and bridge domains instead of switching between the different applications. You can install the plugin by visiting https://<APIC IP>/vcplugin.

The next step is to associate the vCenter domain with our tenant.
