In the cloud vendor space (and really virtualization in general) local disk is practically non-existent. The vast majority of apps these days are stateless and generate very little IO, and even if they do generate IO, it's more than likely going to some kind of network share so that the VM can fail over. If the VM's data is on local disk, you can't migrate it to a new host if the host it's on dies (along with its local disks). Presuming the other responder is correct about there being 880GB/s of network cards (and that the units are correct at GB/s instead of Gb/s or Gbps), that should be more than plenty. At the largest CPUs, 192 cores would be 4.5 GB/s per core (2.3 GB/s if dual socket). That's more than enough; I see a lot of dual-socket servers with 24 or so total cores running on 10 Gbps or maybe bonded 10 Gbps. That's about 100 MB/s per core.
