13 Largest Data Centers In The World In 2024 [By Size]

Every day, we create more than 350 million terabytes of data. This includes newly generated, copied, and consumed data. With the ever-increasing popularity of the Internet of Things (IoT), this data generation rate will grow even more.

Where is all this data stored? 

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. This proliferation of data has enabled significant advancements in fields ranging from finance and healthcare to transportation and entertainment, reshaping how we live, work, and interface with the world. 

Today, we have more than 8,500 data centers that handle small and industrial-scale operations.

In this article, we have mentioned the 13 largest data centers in the world by their size and capacity. They are all built in a large area and consume as much power as a mid-size town.

We have also considered other crucial factors like power usage, number of servers, storage capacity, and complexity of the cooling and power management systems. These factors collectively give us a holistic view of the data center’s scale and capability. 

Did you know global data centers consumed 416 TeraWatt-hour in 2016, about 40% more than the entire United Kingdom?
