It's been the case for a good while now. Microsoft's strong financial results are heavily reliant on the cloud side of its business, and the most recent quarterly results are no exception. Of the total $52.9 billion revenue recorded, 22.1 was from the segment 'Intelligent Cloud' - the highest Q3 figure so far, which translated to $9.5 billion of operating income.
Satya Nadella, Microsoft chairman and chief executive officer commented on the results: “The world's most advanced AI models are coming together with the world's most universal user interface - natural language - to create a new era of computing," adding: "Across the Microsoft Cloud, we are the platform of choice to help customers get the most value out of their digital spend and innovate for this next generation of AI.”
