Presumably this is a public OpenStack cloud? If so...

It's been a while since I worked at a public OpenStack cloud, but most
I would imagine will auto create a tenant network and router (if they
can afford the public IPv4s for the router :)) and then when a user
creates an instance it just ends up on that initial "default" tenant
network. This is usually left to the public cloud to implement during
their customer on-boarding process. That is assuming the public cloud
is allowing tenant "private" networks, which not all would do. There
are other models.

Now, a load balancer, if that is required, is different and bit harder
if you mean one that is managed by the OpenStack cloud, as opposed to
a user creating their own LB instance.

Perhaps what you are really thinking about is the simplicity of a more
"VPS" like interface, ala Digital Ocean (and now somewhat mimicked by
AWS with uh, LightSail I think). I've always thought it would perhaps
be a nice project in OpenStack to do a simple VPS style interface.

Thanks,
