Bulk loader location

Is part of Dgraph Binary.

Anywhere, at least the versions should be the same.

The Bulk is an offline tool. But it needs a Zero group to lease UIDs. All Alphas should be shutdown. For bulk. But for Live Loader, you need the whole cluster running. And the Live also needs to lease UIDs from the Zero group. And write the data in the Alpha groups.

Not sure what you mean. But you can run Dgraph’s binary anywhere. But it needs to reach the cluster from outside if the case. And also have the same version of the cluster.
