Frustrated Ising Model

I've read in an article that the 1D Ising Model in a random field is a frustrated system. But what does it mean for the 1D RFIM to be frustrated?

The internet is very unhelpful. I'd appreciate it if someone could answer this for me.

Thanks.

Frustration usually means that there is an infinite degeneracy of the classical ground state. The random field effectively turns the system into that of a spin glass, where the interactions between spins will become effectively random. A spin glass has lots and lots of degenerate states, so I guess this is where the frustration comes in.
