Microsoft (Azure UK)
Microsoft serves the UK through two Azure cloud regions, UK South in London and UK West in Cardiff, the infrastructure behind Azure, Microsoft 365 and Copilot for UK customers. It mixes leased capacity in third-party data centres with its own facilities, and has committed large sums to expand UK AI infrastructure. For buyers, the question is less which buildings it owns than where its cloud regions and AI demand concentrate.
