What these trends mean
1) AWS is growing faster than Amazon overall
In 2025, AWS revenue grew 20% year over year, compared with Amazon’s consolidated net sales growth of 12%. In practical terms, that means AWS contributed a growing share of Amazon’s total revenue base.
2) AWS remains Amazon’s biggest profit engine
AWS operating income was $45.6B in 2025, up from $39.8B in 2024. Even though AWS is a smaller share of Amazon’s total sales than retail, it often contributes a disproportionately large share of operating profit.
3) The infrastructure footprint keeps expanding
AWS’s current footprint spans 39 Regions and 123 Availability Zones, with additional Regions and AZs announced. This matters because Regions and AZs are the building blocks for lower latency, data residency, and high-availability architecture.
