A week ago I was writing about the latency and bandwidth challenges of long-distance vMotion and why it rarely makes sense to use it in disaster avoidance scenarios (for a real disaster avoidance story, read this post ... and note no vMotion was used to get out of harm’s way). The article I wrote for SearchNetworking tackles an idea that is an order of magnitude more ridiculous: using vMotion to migrate virtual machines around the world to bring them close to the users (follow-the-sun workload mobility). I wonder which islands you’d have to use to cross the Pacific in 10ms RTT hops supported by vMotion?
