The two I see on a regular basis is Storage and Network through SRIOV. The other one that is coming up in discussions more and more is GPGPU resources. I know amazon offers this but TBH I'm ignorant as to how they provide this functionality, whether the device is provided by pass-through or whether it's accessed in some other means.
