One reason why companies would rather get fleeced by aws etc. is that hosting your own server is both troublesome and expensive. This isnt much of a problem if you live in the temperate region but it is a HUGE problem if you live near the equator. Temperator can easily rise up to 33 degrees centigrade and beyond and maintaining a server without round-the-clock cooling in an air-conditioned room is close to impossible(unless your server is a single raspberry pi). That's why people would rather pay for Iaas services, sometimes it is simply cheaper for someone else to host it.
