Running some of the world's largest data warehouses is no easy task, and now Mark Zuckerberg is revealing the high-tech technology behind how they do it.

With more than 1.13 billion daily active users (as of September 2016) it comes as no surprise that Facebook is the third-busiest site on the internet. All that traffic results in a lot of data, in fact, Facebook processes more than 600 TB of information a day which requires an incredible network of warehouses which store upwards of 300 PB of Hive data.

Everyday Facebook is expanding as users uploads millions of pictures and videos. The introduction of 360-degree videos in addition to the 1 million websites and hundreds of thousands of applications which Facebook services requires the company to store the data within massive data warehouses.

Currently, the constant increase of traffic requires the data centers to be expanded. As of now, Facebook is in the plans of constructing two immense warehouses of  307,000 square feet 487,000-square feet respectively.

Perhaps the most interesting of which is the Luleå data center located in Sweden. The center is just over 100 km south of the Arctic Circle, making the climate extremely cold all year round. Typically the temperature sits no higher than 10°C (about 50 °F). Fortunately, the cold air is ideal for cooling down the servers. Instead of utilizing large air conditioners, the Luleå center simply pumps the outside air in.

Twelve local hydroelectric plants generate the electricity from nearby rivers, a necessity to operate the warehouse. The strategic placement enables the entire system to remain 10% more efficient while simultaneously using 40% less power when compared to traditional data centers. Surprisingly, despite the massive savings, the complex is the size of six football fields.

Contradictory to the name, everything that is stored on the 'cloud' is actually directed to a data warehouse similar to Facebook's. Every picture, like, and candy crush request makes its way into a server where it is stored for eternity- or at least until someone shuts it off.
