I'm not sure if the idea is growing on me or what, but the notion of a data center on a ship doesn't sound as silly as it did the very first time I heard it. Back in January of this year IDS (International Data Security) introduced us to the idea of putting containers on ships that were due to be scrapped.
There is an update now on how the company is coming with the idea, and they also do a nice job of explaining how it is accomplished and some of what the value proposition is. I asked questions about the business model, security and fiber, and they have addressed those in the comments section.
Check out the update and answers here.
