I think that leveraging external services and APIs are a KEY THING here - it enables you to focus just on your business logic, and FaaS enables you further to not even manage the server your code is running on.
Regarding monitoring - at Epsagon (epsagon.com), we are focusing on automatic end-to-end monitoring of the ENTIRE architecture, rather than of a single Lambda - which we found out is the main challenge in serverless today. Feel free to contact us and try it out our beta.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
