Thank you for response, Kisan! I agree that a lot of information produced by seller is a marketing trick. It should be — Amazon is a commercial company. However, server-less architecture, which is the modern way to say “I have no idea what a server is”, helps businesses to shift focus towards business needs from technical details, e.g. provisioning servers and setting up infrastructure. Form my perspective, Lambda is a good way to deploy and use code right now even if there is no infrastructure at all. And it really could be used for free in some cases.
