Answer 2

The basic idea is that you run a service on a whole farm of servers managed by someone else, so you don't have to care about maintenance.

This makes it way easier to scale things, since you just have adjust some number in the control panel and the cloud (just a fancy name for datacenter) will start your program on new servers / VMs.
