The problem with statement like "this looks too complex" is that it lacks substance and is used as a stick to beat people with, and often has alternative meanings.

To combat this, you need to justify the complaint.

In the case of lambda, I think being tied into an ecosystem of things that you can't run locally is a net loss, but Amazon has done a terrific job at making a bunch of people not super comfortable with compute, see just running a share-nothing process as the way to bridge the gap, like PHP never existed.

Same thing happens with IT orgs that end up owning cloud. You get azure, regardless of whether you want such a thing.
