But how big are your microservices ? How many did you build ? A monolith that has hundreds of commits is very worth separating it. But do you break it on 10, 100, 1000 microservices ? We have a case where we have 20 people managing 40 microservices. Way too granular. In the general literature there is not good consensus finding boundaries and rightsizing. Many authors just duck the question.
