The thinking on efficiency vs scalability is largely influenced by the US tech company meta where founders give up equity so they don't have to worry about profitability for a very long time.

In that case, it is preferred to burn piles of cash on AWS instead of potentially needing to sacrifice revenue because you can't scale quickly enough.

An architecture that is not scalable is considered a failure whereas one that is complex and inefficient is much more tolerated (as long as it can scale out) ... at least until the funding dries up or Wall Street activists get involved.
