Pros
Primary pro is Infrastructure-less. Let us consider story of Pinterest company . It start up company used Amazon EC2(Elastic cloud) and hosted their application . Amazon EC2 is brilliant architecture which can be expanded the CPU usage of servers on traffic increase. Now you can see that Pin Interest did not worry about server setup , software resources and employees for handling those. it just concentrated on their main business to server the users rather than focusing of infrastructure.
Pinterest pays about $52 an hour to Amazon during peak hours of the day, and about $15 during the night when traffic on the app is less (most of its customers are in the US).
