Here's what I don't understand about the cloud. I'm assuming it is just a network of computers. If someone wanted to have their own functional social media network, why do they need, for example, Amazon? Do you need a host if you have your own network of servers?
I am thinking server is just another word for computer but I may be picturing this all wrong.
(hey ... you ... offa my cloud!")
But then I don't understand the business model to begin with. I hate getting targeted ads; I find it quite creepy. Frankly by the time you've bought into a cloud IMO you've already gone full Orwell. Or worse. "Please put me under surveillance, I don't want to miss any ads on tactical equipment or one easy trick to burning belly fat!"
