2908 questions of the kind that actually get asked — in interviews, in architecture review boards, and by the person who has to run the thing at 3 AM. Every answer states the trade-off rather than the slogan, and says when the obvious choice is the wrong one.

5 questions in Serverless vs Containers.

  1. Serverless vs Containers advanced

    A grocery-delivery marketplace moves its order-status API from long-running containers to per-request functions to stop paying for idle capacity overnight; traffic swings about 20x between trough and the evening peak. What did the team buy, and when does the bill arrive?

  5. Serverless vs Containers advanced

    An image-derivative pipeline runs as functions: about 270 million invocations a month at roughly 1.8 seconds and 2 GB of memory each, costing about 16000 dollars a month at 2026 per-invocation prices. The team wants to move it to a container fleet on one-year reserved capacity. Give the sequence, say where output can diverge, and name the point of no return.
