In recent years, Microsoft's market share of cloud spending has been making impressive gains. Its market share is now only ~11 percentage points behind Amazon. This chart shows the power of Microsoft Office 365.
"As spending on cloud services continues to rise inexorably, Amazon's worldwide market share increased by over a full percentage point to almost 34%. Google also saw a meaningful uptick in its market share during the quarter. Amazon, Microsoft and Google combined had a 65% share of the worldwide market in the quarter, up from 61% a year ago. In aggregate all other cloud providers have grown their revenues by over 150% since the beginning of 2018, though their collective market share has plunged from 49% to 35% as their growth rates remain far below the market leaders."
It will be exciting to see how the cloud market develops over the next years and if Microsoft
$MSFT will continue to gain market share.
