Networking isn't really controlled by systemd but by NetworkManager. I usually just yum remove NetworkManager* and then everything works just as it did in CentOS 6.
Note: NetworkManager is in CentOS6 too, and is part of the default workstation install. The NM in CentOS7 is a bit more polished than the NM in CentOS6, but it is configured in the same way, using files in /etc/sysconfig/network-scripts/ (using the ifcfg-rh NetworkManager plugin). In both cases, you can remove NM and use the 'network' service instead.
You can disable NetworkManager for now in CentOS-7 and use the network service .. but in reality I am not sure how long that is going to be 100% true. In fact, things like dnsmsq and even libvirt/qemu are becoming much harder to configure to work via the network service and are pre-configured to work with NetworkManager. (Don't yell at me, not my decision :D)
I have decided it is likely better to bite the bullet and learn how to use and configure Network Manager if you are going to do anything other than very simple things with your network .. at least on CentOS-7 or higher (ie, Fedora > 18, etc.).
Again, one CAN still use the network service .. but most documentation available now assumes instead that Network Manager is being used.
systemd-networkd is becoming increasingly capable and popular though so NetworkManager might not actually stay around for too long.
Saying the same differently: systemd gradually takes over everything ;-(
