With cloud computing you get someone (or at least some entity) to blame when things go wrong which apparently has some value too. Also, if you don’t need a lot of resources cloud can be cheaper than setting up whole infrastructure by yourself, but that has a ton of variables. Plus with cloud there’s often option for colocation/high availability/ddos protection and other stuff around which can be pretty expensive to build yourself.
Obviously if you try to shoehorn your current modrate sized esx/hyper-v/whatever environment to the cloud as is, that’s going to be expensive.
