Company Subsea Cloud, which wants to build commercial data centers offshore, is progressing towards its physical launch. The company plans to erect a pod near Port Angeles, Washington state.

It will be followed by two other projects in the "Jules Verne" pod, a 6m (20ft) shipping container submerged around nine meters underwater, able to accommodate 800 servers. With this goal at hand, physical security breaches of a Subsea Cloud appear to be nearly impossible.

"You can't do it with divers. So you're going to need some very disruptive equipment. You can't do it with a submarine; they don't go deep enough. So you'll need a remote-operated vehicle (ROV), which is very trackable. It takes care of a lot of the physical side of security, and I'm finding that many military industries want to use these for their physical security."

This company appears to be starting shallow water tests, similar to Microsoft's Natick series of experiments, which turned into a two-year trial off the coast of Scotland in 2018.

While Microsoft's series of tests, and Beijing Highlander's commercial data centers, use pressure vessels, Subsea Cloud uses a shipping container, with internal and external pressure equalized.

"As subsea engineers, we've designed ours to be versatile while maintaining its design integrity," Reynolds told us earlier this year. "The data center pods will work in shallow depths just as they will at deeper depths. The design ensures that the pressure inside the housing equals the pressure outside at any depth – we make no changes to accommodate different depths because we don't have to."

"Data center space rental is similar to leasing an office space. Our leasable spaces provide our tenants' network connections, stable power supply, cooling, and security systems," she said. "We ensure the 'facility' is capable of providing the required IT services while being underwater: We build, deploy and maintain subsea data centers. We monitor the asset, and we attend to it. We are responsible for the hardware insofar as its environment, including permitting and physical maintenance."

The article's post suggests that the company already deployed a data center for a client, but one that was resistant to service "This is the case with our first deployment, which was for tactical, transitional purposes and which we could not maintain due to the nature of their environment and use case."
