It's pretty easy to start, you can still do exactly the same setup as you had just using exactly the same stuff (spin up a VM, install stuff, go). But then start using the cloud storage instead of disk, it takes minor code changes, etc. And go from there. However you pay a LOT more for the same performance. A rented bare metal server for £700 a year will cost you like £7000 on AWS or Azure to get the same sort of performance. The performance of the cheap servers in the £20-£50 range is absolutely abysmal. Unless you have a good reason to use cloud computing, like actually needing to ramp up, ramp down, or large storage needs, avoid it. Unless you just need to be able to put it on your CV.
