Ask HN: Is serverless worth it in some cases?
6 by codegeek | 8 comments on Hacker News.
I know serverless etc. gets flak from a lot of us (for genuine reasons) and in many cases, you are better off with servers. However, there must be cases when it does make sense. What would those be ? The idea is def. exciting that I can put an API behind something like Lambda and may be an API gateway and boom, it can scale infinitely. Is anyone truly getting good ROI from serverless ? Would love to hear positive use cases and benefits.
