A lot was said good about serverless, and I was a big proponent of going ”all in”, but now as CTO of small startup I am careful with it.

From my experience of 4 years with serverless in AWS following problems have been identified:

- Difficult to debug

- Difficult to collect logs - Lambda@Edge

- Slow cold starts

- Frontend and NodeJS bundling are problematic - size limits, slow and unpredictable problems

- Pricing are difficult to estimate

- Careful planning needed for network and architecture - how lambdas work together

- Workflow orchestration might be needed

What is serverless good for?

- Queue processing

- Event processing

- Internal infrastructure code
