We've tried node.js as a managed VM a few times before this. One of the biggest pains is logging. Despite documentation implying that JSON logs are supported (can't find this anymore, maybe it was removed), we still haven't been able to get GCP to read JSON logs. You lose out on all of the nice filtering and request grouping provided by the GCP log viewer.

The issue is here[0] and it would seem they still haven't addressed it a year later.
