Microsoft Plumbs Ocean’s Depths to Test Underwater Data Center - The New York Times

Sunk cost

"Such a radical idea could run into stumbling blocks, including environmental concerns and unforeseen technical issues. But the Microsoft researchers believe that by mass producing the capsules, they could shorten the deployment time of new data centers from the two years it now takes on land to just 90 days, offering a huge cost advantage.

The underwater server containers could also help make web services work faster. Much of the world’s population now lives in urban centers close to oceans but far away from data centers usually built in out-of-the-way places with lots of room. The ability to place computing power near users lowers the delay, or latency, people experience, which is a big issue for web users."
