Microsoft plans to spend billions building 50 to 100 new data centres annually with expectations to expand its Microsoft Azure data centre presence into 10 new countries by the end of this year. The public cloud and software giant unveiled its aggressive data centre built-out plan during the launch of Microsoft’s new immersive data centre virtual tour experience, which provides a free online tour of a simulated Microsoft data centre that details the company’s investments in security, sustainability, reliability and innovation such as its successful undersea data centre experiment. Although the Redmond, Wash.-based company didn’t unveil the locations of all its new planned data centres, Microsoft recently announced plans to spend US$1 billion over the next five years in Malaysia to build several data centre regions. Microsoft is also building new data centres everywhere from Fulton County, Georgia, and San Antonio, Texas, to Israel as it continues to expand its Microsoft Azure cloud offerings across the globe.
