San Antonio Data Centers

San Antonio's data center market is structurally distinctive among Texas Triangle metros precisely because of the metro's federal cybersecurity and military intelligence concentration. The metroplex hosts approximately 30-40 operational data center facilities anchored by Microsoft's massive Westover Hills datacenter campus, the Army Corps of Engineers' San Antonio operations, the broader 24th Air Force / Sixteenth Air Force cybersecurity substrate at Joint Base San Antonio (Lackland), the National Security Agency / Cyber Command Texas substrate, plus continued continued enterprise and colocation operator concentration. Microsoft's Westover Hills concentration plus continued continued military-and-intelligence cyber operator concentration positions San Antonio as one of the most security-focused US data center substrates.

San Antonio's specific data center substrate position requires acknowledging the structurally distinctive water-stress context. During 2023-2024 Stage 3 restrictions, Microsoft and Army Corps San Antonio data centers consumed 463 million gallons of water. Continued continued closed-loop cooling adoption plus continued operator-water-utility coordination supports continued operator concentration but represents a fundamental supply ceiling.
