Microsoft and Facebook have agreed to jointly build a subsea cable across the Atlantic to meet demands for their growing online services. Microsoft had announced a similar initiative last year to connects its data centres around the world. This new partnership with Facebook dubbed MAREA is expected to begin in August and is expected to be completed in October 2017. The cable is expected to carry 160 terabits of data per second according to a statement by both companies.
Google had struck an agreement with five companies in Asia for a similar initiative connecting the United States and Japan. Underwater data centres are expected to be powered by renewable energy at affordable rates because of the eventual lower cost of cooling. This is what Microsoft’s Project Natick is all about with a successful test of a data centre on the seafloor for four months.
