As the demand for data centers in Virginia has dramatically risen, so has the presence of Amazon Web Services (AWS) and Microsoft, in familiar locations such as Northern Virginia, as well as emerging, but lesser-known places like the town of Boydton, Virginia. Data center demand in Virginia is being fueled by an ever expanding need to provide additional compute, storage, and database capabilities to enterprises, both in Virginia and throughout the East Coast of the United States.

Amazon Web Services (AWS) operates data centers in Virginia, in the markets of Ashburn and Sterling (Loudoun), Manassas and Haymarket (Prince William), and Chantilly (Fairfax). While Microsoft has data centers in Virginia, in Boydton (Mecklenburg) and Leesburg (Loudoun), with more under construction.

Dgtl Infra provides an in-depth overview of Amazon Web Services (AWS) and Microsoft’s data centers in Virginia, including where they are located and the individual facility sizes. Additionally, we outline the ongoing and future development potential at select AWS and Microsoft sites to understand how their data center portfolios can scale further. Finally, Dgtl Infra reviews the cloud regions and availability zones of AWS and Microsoft in Virginia, which are supported by their data centers.

Microsoft Data Centers in Northern Virginia

Microsoft is rapidly expanding its data center presence in Northern Virginia, particularly, in the sub-markets of Leesburg (Loudoun County), Aldie (Loudoun County), Manassas (Prince William County), and Bristow (Prince William County).

Notably, Microsoft has established a self-imposed requirement for its data centers to be within 20 kilometers (12.5 miles) of existing data centers in their regional network. This means that for Microsoft to deliver Azure Cloud Services in Northern Virginia, the company needs to have data centers located within either Loudoun, Prince William, and/or Fairfax County.

Importantly, this 20-kilometer (12.5-mile) distance allows Microsoft to meet its service level agreements (SLAs) of latency, resiliency, and reliability to customers in the region.

Below we highlight Microsoft’s existing data center presence and ongoing development at its Northern Virginia sites in Leesburg, Aldie, Manassas, and Bristow.

Microsoft in Leesburg, Loudoun County, Virginia
