AWS IAD 7505 Mason Data Center Manassas: Hyperscale Cloud Hub in Virginia
Status: Fully Operational Hyperscale Facility | Location: 7505 Mason King Ct, Manassas, VA 20109, United States
Project Overview
Amazon AWS IAD – 7505 Mason (site code IAD7) is a purpose-built hyperscale cloud data center strategically located on Mason King Court in Manassas, Prince William County, Virginia, within Northern Virginia's globally recognized "Data Center Alley," the world's largest concentration of hyperscale digital infrastructure. Serving as a foundational availability zone within the Amazon Web Services (AWS) US East (Northern Virginia / us-east-1) cloud region, the facility plays a critical role in delivering highly available, low-latency cloud infrastructure for enterprises, government agencies, financial institutions, technology companies, and digital service providers worldwide. Operating as part of the broader Mason Campus, alongside facilities at 7510 and 7610 Mason King Court, the approximately 109,406-square-foot data center contributes to a resilient, scalable cloud ecosystem supporting AWS's expanding portfolio of cloud services. The facility is engineered to accommodate high-density server deployments and provides advanced cloud compute, object storage, database services, networking, analytics, artificial intelligence (AI), machine learning, and high-performance computing (HPC) capabilities, enabling customers to run mission-critical workloads with exceptional scalability and reliability. Designed with resilient electrical and mechanical infrastructure, the building supports increasing rack power densities required for next-generation AI and GPU-intensive computing environments. Advanced high-efficiency evaporative dry cooling systems optimize thermal performance while minimizing energy and water consumption, supporting Amazon's long-term sustainability objectives. The facility is interconnected through dedicated dark fiber backhaul links and AWS's extensive regional fiber network, providing secure, high-bandwidth, and ultra-low-latency connectivity between multiple availability zones, cloud regions, internet exchange points, and major telecommunications carriers. Redundant utility feeds, uninterruptible power supply (UPS) systems, backup generators, enterprise-grade physical security, continuous environmental monitoring, and 24/7 operational management ensure maximum service availability and operational resilience. Operating under Amazon's commitment to matching its electricity consumption with 100% renewable energy, Amazon AWS IAD – 7505 Mason delivers a secure, scalable, energy-efficient, and future-ready hyperscale platform that supports the continued growth of cloud computing, artificial intelligence, and enterprise digital transformation within one of the world's most strategically important cloud infrastructure markets.
