ArcelorMittal has named Microsoft Azure its primary cloud platform, deepening a partnership the steelmaker is using to rebuild its digital operations around artificial intelligence.
The company announced the expanded collaboration on Monday, casting it as the technical spine of a ‘Cloud First, Data Centric’ strategy that spans a business with steelmaking in 14 countries and a presence in around 60.
The agreement makes Azure the default home for ArcelorMittal’s data and applications, alongside Microsoft Fabric for data integration and Microsoft Purview for governance.
The steelmaker also plans to build on Microsoft Foundry, the platform Microsoft sells for developing and running AI models and agents.
The move arrives as the real cost of enterprise AI comes under fresh scrutiny, with large customers weighing the price of running models at scale against the efficiency they are promised. ArcelorMittal’s argument is that standardising on one cloud reduces its dependence on legacy systems and makes those gains easier to reach.
