Seconded, just got done with one of these. Literally 1200 separate lambdas, step functions, hundreds of kinesis streams, and sqs topics plus a smattering of ecs fargate tasks for when invariably something takes longer than the max lambda time. And oh god all the stupid supporting infrastructure to build layers. There primary app was Rails, you know what replaced all of it? Running the synchronous tasks on the app servers themselves, the async ones on Sidekiq and changing the max instances on the two ASGs. The only downside has been not being able to meme about how we're web scale anymore.
