Microsoft Azure is the cloud computing platform through which Microsoft sells compute, storage, networking, database, and AI services to businesses and developers worldwide, underpinned by one of the two or three largest self-built data center footprints on the planet. As of 2025, Azure operates dozens of geographic “regions” (each typically made up of multiple physical data centers) across the Americas, Europe, the Middle East, Africa, and Asia Pacific, with new regions such as Austria and Belgium announced in 2025. What sets Azure apart today is its rapid build-out of purpose-built AI “Fairwater” superfactories — starting with a Mount Pleasant, Wisconsin campus that Microsoft has called home to the world’s most powerful supercomputer, and a second Fairwater site near Atlanta, Georgia, the two of which are directly networked together to train frontier AI models such as those used by OpenAI. According to Synergy Research Group, Microsoft holds roughly 21-25% of the global cloud infrastructure market as of 2026, trailing only AWS, and is consistently identified alongside Amazon and Google as one of the handful of true hyperscalers, each maintaining data centers across dozens of markets on every populated continent.

Microsoft Azure AI Data Centers
Microsoft's flagship AI infrastructure is its "Fairwater" program: a first campus in Mount Pleasant, Wisconsin that went fully operational in mid-2026, and a second in Fayetteville, Georgia (near Atlanta) that came online in October 2025. Both use a distinctive two-story building design with closed-loop liquid cooling to pack in dense racks of NVIDIA GB200/GB300 Blackwell GPUs, with the Atlanta site supporting racks around 140kW and rows over 1,300kW. The two campuses are linked by a dedicated fiber "AI WAN" so their GPU fleets can act as a single distributed supercomputer, described by Microsoft as the world's first planet-scale "AI superfactory," with OpenAI reported as among the largest users of the Atlanta site's capacity.

Common Questions
Does Microsoft Azure have dedicated AI/GPU data centers?
Yes. Microsoft's "Fairwater" program consists of purpose-built AI datacenters, the first in Mount Pleasant, Wisconsin and the second near Atlanta, Georgia (in Fayetteville, on land owned by QTS), both using two-story building designs, closed-loop liquid cooling, and hundreds of thousands of NVIDIA Blackwell-generation GPUs, and the two sites are linked by a dedicated fiber "AI WAN" to function as a single distributed AI superfactory.
Is Microsoft Azure a hyperscaler?
Yes. Synergy Research Group and other industry analysts consistently name Microsoft, alongside Amazon and Google, as one of the world's leading hyperscale operators, with Microsoft accounting for a large share of global hyperscale data center capacity and holding roughly a quarter of the global cloud infrastructure market as of early 2026.
Where is Microsoft's largest known AI data center campus?
The Mount Pleasant, Wisconsin "Fairwater" campus, built on land originally set aside for a Foxconn manufacturing plant, was Microsoft's first Fairwater AI datacenter and became fully operational in June 2026, with Microsoft describing Wisconsin as now home to the world's most powerful supercomputer.
Does Microsoft Azure sell colocation space to customers?
No. Azure sells cloud infrastructure and platform services that customers consume remotely; Microsoft builds and operates its own data centers (and leases some space from operators like QTS) strictly to run its own cloud and AI services, rather than renting rack or cage space to third parties.
Does Microsoft Azure offer cloud services?
Yes — we've identified 28 facilities where Microsoft Azure may offer cloud services. Please contact Microsoft Azure directly to confirm current availability and terms.
