Indeed. It's easier to change a monolithic stack while you're still discovering the actual architectural requirements of the particular problem you're solving.

Indeed. It's easier to change a monolithic stack while you're still discovering the actual architectural requirements of the particular problem you're solving. As you get a better understanding of how you need to handle things, where the performance bottlenecks are, etc., you can start breaking out pieces that would benefit from being isolated. It's extremely unlikely that in the short term (first year(s)) of the application being used that the engineering would benefit from a micro services architecture.
