Right, from the revenue report: "Commercial cloud revenue grew 103%". This appears to be the largest section of growth reported, so it looks like Microsoft is doing pretty well in the cloud space.
Improving growth does mean either Microsoft's doing something right and/or the size of this market is increasing. But seeing a growth number this high means you should be very skeptical that cloud products will be able to carry the rest of Microsoft on their back going forward, or successfully challenge market leaders.
