Amazon did not detail its total data center power consumption, but from October 2024 to October 2025 it added a total of 3.8GW. "To put that in perspective, we're now double the power capacity that AWS was in 2022, and we are on track to double again by 2027," CEO Andy Jassy said at the time.<br>Its cloud business operated a total of 56.839 million square feet (5.28m sqm) of data center and office space in 2025, according to its 10-K filing. That represents a 16 percent increase over 2024.<br>About half of that space is owned by the company, with the rest leased. Its data centers consumed 2.5bn gallons of water in 2025, the company revealed last month.<br>While Amazon's total footprint is unknown, for context, the UK government found that the country had approximately 1.6GW of data center capacity in 2024. Data center capital Virginia has as much as 8GW in capacity, JLL Research found, with another 4GW underway.<br>As for Amazon's rivals, exact figures are also undisclosed. Microsoft stood up 1GW of data center capacity in what it calls FY2026 Q2, but that is actually the same timeframe as Amazon's Q4. In its FY2025, Microsoft brought online a total of 2GW.<br>Despite growing competition from neoclouds, Amazon Web Services remains the world's largest cloud provider, with Synergy Research reporting a 28 percent global market share for the business. Microsoft was second, with 21 percent, while Google came in at 14 percent.
