Microsoft’s Strategic Investment in Subsea Cables Explained

Microsoft, a technology giant known for always being at the forefront of innovation, recently revealed its plans for a global data infrastructure boost. On Monday, the company announced an ambitious strategy to enhance its data centres’ interconnectivity using underwater fibre optic cables.

In an effort to propel the speed, capacity, and latency of data delivery to its customers globally, the corporation has reached agreements with Hibernia and Aqua Comms. According to these deals, Microsoft will invest in separate subsea cables with both companies, which will extend its data center infrastructure from North America to Ireland, eventually reaching the United Kingdom.

Adding to its strategic moves, the tech giant also declared its involvement in a consortium of major Asian telecom operators, including China Mobile, China Telecom, China Unicom, Chunghwa Telecom, and KT Corporation. This cooperation sees TE SubCom serving as the cable supplier. As an active participant, Microsoft will construct its first-ever physical landing station on U.S soil, bridging North America and Asia. This venture, known as the New Cross Pacific (NCP) Cable Network, is set to expedite data connections, assist Microsoft in competitively pricing cloud services, promote job creation, and stimulate local economies.

By expanding investments in subsea cables, Microsoft aims to provide customers with unparalleled access to scalable and highly reliable data, regardless of their location.

Microsoft’s cloud services are gathering momentum, with the user count for its 365 subscription service now exceeding the 10 million mark. Microsoft joins a cadre of tech heavyweights, including Facebook and Google, who are making notable investments in subsea cables. On the African continent, MainOne and Glo in Nigeria, alongside South Africa, are also enriching their infrastructure through similar investments.
