- This architecture binds us to AWS. Have we estimated the engineering effort to remain cloud-agnostic in case we need to move to Azure next year?
- I see we're using Postgres. Have we considered how we’ll handle horizontal sharding if our user base grows by 1000x in Q4?
- This synchronous API call introduces tight coupling. Shouldn't this be an event-driven architecture to handle back-pressure?
All sound like things that are easy to ask, sound prudent to management, but are impossibly expensive to answer or implement for a feature that just needs to ship.
