Yeah, I think it's a trade off. Certain services can be a no-brainer, but others will cause pain if your particular use case doesn't align precisely with the service's strengths and limitations.
DynamoDB vs RDS is a perfect example. Most of that boils down to the typical document store and lack of transactions challenges. God forbid you start with DynamoDB and then discover you really need a transnational unit of work, or you got your indexes wrong the first time around. If you didn't need the benefits of DynamoDB in the first place, you will be wishing you just went with a traditional RDBMS vs RDS to start with.
Lambda can be another mixed bag. It can be a PITA to troubleshoot, and their are a lot of gotchas like execution time limits, storage limits, cold start latency, and so on. But once you invested all the time getting everything setup, wired up...
