AWS Lambda Silent Crash – A Platform Failure, Not an Application Bug [pdf]

AWS has a clear policy of not providing support for user application code. I’ve never worked at a company that had enterprise level support with a dedicated TAM. It might be different there.

However if it is worth anything I did work at AWS for 3.5 years (AWS ProServe). I knew almost immediately what the issue was as soon as I read the article and knew it was documented and expected behavior.

Having worked with Lambda since it was announced over 10 years ago, it was also clear to me. However, I can also understand if one was new to it and read zero documentation about its execution model, they might be confused. I'd expect someone with experience to ask "am I really the first person to encounter this 'obvious bug'?" though.
