I like the explanation of cloud terminology by @jcfarris in his interview on Screaming in the Cloud . AWS has accounts because it grew out of Amazon retail and that's what you used to buy underwear. GCP has projects because of their developer first mentality. Azure has subscriptions because their focus is on how they'll charge you. https://www.lastweekinaws.com/podcast/screaming-in-the-cloud/Solving-for-Cloud-Security-at-Scale-with-Chris-Farris/
