Microsoft has played down the weakness of its cloud computing division in its latest results, saying that nearly three-quarters of its cloud customers are using more than one product on offer. Third-quarter revenue in its intelligent cloud business grew just 3 percent to $6.1 billion, despite revenue from Azure more than doubling year-over-year. Investors were disappointed and its share price fell when it announced earnings on April 21. But Azure is just one part of the cloud business which also includes its Office 365 apps and its customer relationship management software Dynamics. Jason Zander, corporate vice-president of Microsoft's Azure team, said that many of its customers are choosing to use several of its cloud products.

"If you look at the cloud segment, we're actually getting triple digit revenue growth, we have about 85 percent of the Fortune 500 using the Microsoft cloud. Keep in mind our cloud efforts are Office 365, as well as Azure and Dynamics," Zander told CNBC in a TV interview. "So we have over 74 percent using more than one of those services. So our uptake is going incredibly well from that perspective and this is rarely a good time for us to be pushing for market share and getting more and more customers on board."
