Is there a Cloud over a set of Islands?

I was recently on an island and it got me thinking about whether a set of close islands can support a highly mobile cloud? If not what would be needed to make the Islands Cloud safer from the vagaries of Mother Nature, such as hurricanes, volcanoes, and earthquakes. Can a cloud provider be based on an island? or would it need to be on every island? Only the mainland?

  • Fast interconnects between its various locations
  • Redundancy in the form of building, functionality, etc.
  • Protections from all forms of disasters
  • Treaties

So how would you move a business to or from an Island? Is this where the Cloud becomes a mature component? If so how much cloud do you need?

VMsafe – Vendor Implementations at VMworld

With the advent of existing VMsafe products from Altor Networks, Reflex Systems, and ones on the horizon from Trend Micro and others in the security space, all administrators should have a clear understanding of how they work under the covers.  Where does VMsafe appear within the stack? Is VMsafe on the incoming physical NICs, within the vSwitch, portgroups, or before or after the vNIC? Can we expect the other aspects of VMsafe to be the same? While I was discussing VMsafe with the vendors, VMware was also going around and talking to all the VMsafe vendors for VMware TV shots.
