Literally author is asking for something in the cloud which is abstracted away, fast, easy to use and easy to debug. This is not possible imho. There are always trade-offs. You can't get all of them for "free". e.g serverless services will be slower than your own setup, like always. Debugging, I'm not sure but I don't think it will be as easier as your own setup ever.
I don't know. What he's describing sounds very close to what I've been working on, all AWS Serverless with lambdas and SQS and DynamoDB, with config (CloudFormation) via code in BitBucket. I can launch a new lambda in less than a minute with a couple of aws-sam-cli commands, and get responses from curl in less than 2ms.
I mean, nothing's perfect, but AWS Serverless seems to be the closest thing I've ever seen to truly abstracting away everything but the actual code.
