I think the complexity aspect is a fair criticism of Lambda. The way I look at it is that, as a developer, I want all the advantages of serverless (per ms billing, scaling up instantly, scaling down to 0, etc) while not having to worry about the function level nuances of tooling and deploying. Having struggled with scaling large systems in a past life, I personally lean more towards taking on the burden of tooling instead.
