I suppose VXLAN makes a lot of sense in cases where either the network
provider does not support MPLS, or the infrastructure owner prefers to
handle his own overlay over IP, without needing to complicate their
lives by purchasing an overlay service from another provider.

If, however, a network already operates an MPLS network, EVPN could be a
simple(r) way of re-using existing infrastructure.

That said, I'd probably consider VXLAN if I want VM's to natively
participate in a Layer 2 domain, without needing to necessarily involve
the network.
