It's a little more difficult to figure out how much revenue Microsoft generates from cloud computing. In its fiscal 2016 Q4 report, the company said that its "Intelligent Cloud" revenue increased 5 percent to reach $6.7 billion. That makes it seem like Microsoft does more cloud business than Amazon, except that Microsoft includes its very substantial server revenues along with its Azure cloud computing service in the Intelligent Cloud category. The company has previously said that its Azure business is on a $10 billion annual run rate, or around $2.5 billion in revenue per quarter. Most market analysts put it in the number two spot behind Amazon.
In addition to its Azure IaaS and PaaS offerings, Microsoft also has several SaaS offerings, including its Office 365 products, the online versions of its Dynamics line of enterprise software and its online developer tools.
Although it hasn't always been considered one of the "big three" cloud computing vendors, IBM's cloud business has been coming on strong. In its most recent quarterly report, IBM said that its "cloud-as-a-service revenue was up 50 percent," and had an annual run rate of $6.7 billion.
IBM's most visible cloud service is its Bluemix PaaS, which is aimed primarily at enterprise development teams. The company also a lot of enterprise software on a SaaS basis, and it sells cloud infrastructure, cloud management tools and cloud managed services.
