Yes, absolutely. Monitoring and debugging remains a challenge in serverless because for one
you can't ssh into a running lambda. Fortunately, the serverless landscape is maturing: services such as AWS X-Ray, Iopipe, Dashbird, and a few others have emerged to help solve the visibility problem: they help you see inside your lambda functions.

As serverless continues to grow and mature, I expect we'll see more solutions in this space.
Thank you for reading!


Great read!

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 (, 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.
