One of the core value propositions of AWS is to take advantage of the various services to scale more easily with more linear costs than you would be able to otherwise. Writing and maintaining code that sets up and configures S3, SQS, SNS, DynamoDB, and Lambda is a non-zero cost, but if it then reduces the amount of code I have to write and maintain to "write the application," that's often a good thing. These services are typically solving the hard and/or tedious parts of the application, so it's actually quite valuable to just focus on developing the core differentiating points of the application instead of solving / maintaining highly available object storage or message queues.
