I know one place that did all of their transactional payment flow through lambdas. There were about 20 lambdas in the critical auth path, and they regularly hit the AWS per-global-account limits.
Another place did all their image processing via lambdas, about fifty of them. They literally used lambdas and REST calls where anyone sane would have done it in one process with library calls. It cost them tens of thousands of dollars a month to do basic image processing that should have cost about $100 or so.
