Very few people are aware of the magnitude of the business represented by data centers. They are the backbone of the digital world, home to the cloud, artificial intelligence (AI), our applications, and even the financial services we use every day. And behind them lies a multi-billion-dollar investment that explains why companies like NVIDIA have become stock market giants.
Between now and 2029, an estimated $3.3 trillion will be invested in the construction of new data centers worldwide. To give you an idea of the magnitude, we're talking about an expenditure that exceeds the GDP of many developed countries.
Of this colossal investment, approximately half is allocated to physical infrastructure: buildings, cooling systems, security, and power supply. The other half goes to hardware, where NVIDIA is the main player. Their specialized AI computers dominate the market, and each computing rack can cost up to $4 million. And not just one is installed, but thousands per center.
The factor driving this boom is artificial intelligence. Companies of all sizes, from startups to multinationals, need to train models and process huge volumes of data. Interestingly, small companies with AI experience are now able to compete with much larger companies that are slower to adapt.
According to a recent BBC report, the UK alone plans to build 100 new data centers in the coming years. This trend is repeated in the United States, Europe, Asia, and Latin America: an almost frenetic growth driven by the unstoppable demand for AI and digital services.
Every day, AI platforms receive hundreds of millions of requests. This implies huge variations in electricity consumption, which poses a huge challenge for energy companies.
A key debate arises here: what should be prioritized, energy for homes or energy for data centers? The same is true for water. These digital giants require huge amounts of water to cool their servers. And it would be absurd to reach a scenario where there is not enough water for people while there is plenty to cool computers.
The data center boom is impressive, but it is not without risks. Their energy and environmental footprint is increasingly being questioned, and a balance between technological innovation and sustainability will need to be found.
The big question is how long this exponential growth will last. Are we facing a healthy cycle or a bubble? For now, the reality is clear: demand is unstoppable. Every time we use a chatbot, request directions on Google Maps, or store photos in the cloud, we are contributing to this digital fever.
Data centers are, ultimately, the new gold mine of the 21st century. And as in all "gold rushes," there will be spectacular winners and also risks that we don't yet know how to manage.
