The CSC survey gives some indication that cloud services don’t actually save many businesses very much money, and in some cases they boost costs because they require companies to add new staff with the relevant cloud expertise. But on the other hand, there are some very prominent counterexamples, like Netflix, which claim that using Amazon’s public cloud saves the company a ton of money.
So what’s going on here? Is renting transistors in the cloud cheaper than owning them, or is it more expensive? And if cloud is cheaper for some users and not for others, then why is that the case? Finally, how does the private cloud fit into this picture, and does it pose any threat to the seemingly unlimited growth potential of Amazon?
