I have a simple nodejs server that all it does is receive requests to add/modify/delete data from a mongodb database (hosted by mongodb) and returns a response.
Can I rely on functions for something such simple yet important? Will the functions be able to handle any traffic scalably? ex (10k input outputs/second?)
If yes, where can I get started to learn how to convert my app into functions with NodeJS?

Indeed this sounds like a good use-case for a serverless function. The main thing that I would recommend considering is the current limitations here:
Functions have the following limits:
The maximum execution duration is 30 seconds each for initialization and function execution.
The maximum size of input parameters is 1 MB.
The maximum size of result responses is 1 MB.
The maximum size of artifacts is 48 MB.
Memory is limited from 128 MB – 1 GB, defaulting to 256 MB.
If you fit withing those limits, then you should give it a try!
Regarding the getting started guides, I would recommend starting with the following guide:
Then after that, here are some sample NodeJS functions that you could also take a look at to get you up to speed:
Hope that this helps!
