While it looks beautiful, this is kind of a silly infographic. The data has been collected from https://cloudability.com/, a company that helps you track multiple cloud costs. Why would you be using cloudability if you werent tracking multiple clouds? Thats the whole point of their product.

Cloudability is for much more than just clouds. It's for all the services around it e.g. UserVoice, ZenDesk, Pingdom etc.

Those "services" are delivered as "Software as a Service" (SaaS) aka "Cloud Software".
