Generally vlan and flat networks are "provider" network types while vxlan is 
tunnel network and don't require any configuration from Your provider/DC.
Provider networks can be also "external" networks so can provide access to the 
"internet" for Your cloud. Tunnel networks are isolated and can't have direct 
access to the external world.

See where Assaf explained different types of networks pretty well.
