Lambda is often the way to go, but there are a couple tipping points where it becomes less appealing:

- When you start having to spend a lot of time working around its limitations. (As is the case with all managed services.)

- When the sum of its parts create a distributed system whose complexity costs you more in productivity than it gives back.

Performance limits will get better with time. The complexity cost is more difficult to predict. Hopefully it will improve as best-practices emerge and tooling gets better.
