Virtualizing from an Island?

I was recently on an island and it got me thinking of how would I move my company to the island. The company services people around the world, but would also service local to the island. Does virtualization really help me here? Why do I ask this, because an island is often prone to the vagaries of mother nature: Lava, Flooding, Typhoon, Hurricane, Earthquakes, humidity, desert, power fluctuations, etc. The list is pretty endless. 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?
