Every day, we create more than 2.5 million terabytes of data. With the ever-increasing popularity of the Internet of Things (IoT), this data generation rate will grow even more.
Such huge volumes of data are stored in dedicated facilities called data centers. Although the earliest data centers were built in the 1940s, they became mainstream during the dot-com bubble of 1997-2000.
Current technologies, such as artificial intelligence and machine learning, have taken the wheel and driven us into a data-driven world. Today, we have more than 7 million data centers that handle small and industrial-scale operations.
In this overview article, we have mentioned the 12 largest data centers in the world by their size and capacity. They all are built in a large area and consume as much power as a mid-sized town.
Did you know global data centers consumed 416 TeraWatt-hour in 2016, about 40% more than the entire United Kingdom?
