-TIP: You will learn to code, coordinate and orchestrate a swarm of self-acting nodes.
+networkd is a small and lean service to configure network interfaces, designed mostly for server use cases in a world with hotplugged and virtualized networking. Its configuration is similar in spirit and abstraction level to ifupdown, but you don't need any extra packages to configure bridges, bonds, vlan etc. It is not very suitable for managing WLANs yet; NetworkManager is still much more appropriate for such Desktop use cases.
