The construction of huge underwater data centers may sound like a novel by Julie Verne, but in our case it is something Microsoft is trying to do. 
The company's plan is called Project Natick, and its website states its purpose: "To understand the benefits and difficulties of developing underwater data centers around the world."
Why to build submarine data centers? Customer's approach to better service is the main reason.
Given that so many major cities are coastal, and datacenter buildings are in the middle of nowhere, building submarine centers could improve the performance of services such as Netflix for millions of city dwellers.
In addition, server hosting in an underwater building virtually eliminates the possibility of overheating damage.
And finally, Microsoft says it can map submarine data centers with electric generators or turbines using the tide to move, which could help meet growing energy needs.
The first prototype called Leona Philpot was tested last autumn about a kilometer off the coast of California, 30 feet (about 10 meters) under the water.
The test was done on a single datacenter located in a steel capsule, covered with sensors that watched pressure, humidity, and other factors that helped engineers learn more about the possible challenges they will face in the future.
In December, following a series of successful tests, technicians sent the test results back to Microsoft's headquarters in Redmond for analysis.
Microsoft believes it can install 90 underwater data centers faster than it can build terrestrial.
