Amazon Web Services — Northern Virginia Hyperscale Campus

Amazon Web Services’ Northern Virginia cluster, centered in Ashburn, is the world’s largest data center market concentration. AWS operates dozens of facilities in the region across multiple availability zones (us-east-1), collectively totaling an estimated 1.5+ GW of IT load. This cluster is the primary home of AWS’s AI and machine learning services: SageMaker, Bedrock (which hosts Anthropic’s Claude, Meta’s Llama, and other foundational models), Rekognition, and AWS Trainium/Inferentia chip deployments. The US-East-1 region is AWS’s oldest and most infrastructure-dense, and hosts default deployments for many enterprise AI workloads. Loudoun County, the core of this cluster, has nicknamed itself the “Data Center Capital of the World.” Water usage for cooling has prompted county-level data center moratoriums.
