Amazon’s hidden data centers: AWS quietly operates more than 900 facilities across 50+ countries

New internal documents reveal that AWS quietly operates more than 900 data center facilities across 50+ countries, far beyond the handful of well-known mega-campuses in places like Northern Virginia and Oregon. Nearly half of AWS’s footprint is now hidden inside third-party colocation data centers, with over 440 sites providing fast, flexible capacity that allows Amazon to expand quietly and stay close to customers without waiting for large builds. This vast distributed network underpins the rapid rise of AI, which is driving unprecedented demand for compute, energy, and infrastructure. AWS is investing massively—more than $50 billion in early 2025 alone—and its colocation strategy makes its growth harder for competitors and regulators to track. But the expansion carries increasing environmental costs. Data centers consume huge amounts of electricity and water, and nearly half of U.S. facilities already sit in areas facing water stress. AI workloads intensify these pressures, and many centers rely on evaporative cooling that uses billions of liters of water each year. Although AWS promotes efficiency improvements, custom low-power chips, and a goal to be water-positive by 2030, critics point to unreported indirect water use and the strain on arid regions like Arizona and Chile. Oversight is becoming more difficult as AWS’s footprint spreads across hundreds of jurisdictions. Communities in the U.S. and Europe are pushing back, demanding more transparency about the environmental impact of cloud and AI infrastructure. According to Bloomberg, two-thirds of new U.S. data centers built since 2022 are in high water-stress regions, with just five states accounting for 72% of those projects. Overall, AWS’s hidden global network is powering the AI boom—but also intensifying environmental, regulatory, and community concerns.
