San Antonio Data Centers
San Antonio's data center market stands apart among Texas Triangle metros for its concentration of federal cybersecurity and military intelligence work. Its dozens of operational facilities are anchored by Microsoft's Westover Hills data center campus, the Army Corps of Engineers' San Antonio operations, the Sixteenth Air Force cyber mission at Joint Base San Antonio-Lackland, and the National Security Agency (NSA) and US Cyber Command presence in Texas, alongside enterprise and colocation operators. Together they make San Antonio one of the most security-focused data center markets in the United States.
Water shapes the market. Microsoft and Army Corps data centers in San Antonio drew heavily on the city's water supply during Stage 3 drought restrictions (see Texas Water Supply and Stress). Closed-loop cooling and coordination between operators and the water utility support further growth, but water supply sets a ceiling on how far the market can expand.
