Proper scale
Bookmarked Does this scale down? 📉 by Henrik Jernevad.
How come people never worry about whether it scales down to a low number? Why do people never ask “is this technology suitable for us since we only have 1000 users” or “is it appropriate for us to include this technology since we only have 10 developers”?
I think the pertinent question to ask is "is this solution the most efficient one for our current scale?" And something about having the flexibility to continue to maintain efficiency when the scale changes.
