The missing details
Surveys like this may make it sound as if everyone is moving to the cloud. But the survey questions are usually phrased in a way that if you run just one insignificant thing (out of dozens) in the cloud, you have to tick the "Yes, we use the cloud" box. Then the outcome is portrayed as a big win for the cloud, even if actual usage would be minimal.
Which is why I don't participate in cloud surveys as the outcome doesn't reflect reality in my opinion.
