Interestingly I&#x27;ve hardly seen this &#x27;rewrite&#x27; vs &#x27;no rewrite&#x27; debate regarding to microservices, with all the talk about them.<p>In theory it shouldn&#x27;t be more work (as they are supposed to be so small) than some refactoring in your old (big) piece of software, and you can even rewrite it in a different language.
