Where Lambda bit us is when you need to have compute for longer than 15 minutes which happens when processing large documents. You can split the individual operations on whatever your atomic unit of thing is (eg pages) but the split/merge steps are what kills you. The moment you have to step out of all Lambda the simplicity breaks down and making serverfull/serveless work together is more complex than just going all serverfull. The other painfully annoying thing is when you need state and storage (ie websockets) but maybe that's better now. I know for sure that EFS is still painful.
