The most important benefit of microservices is that allows development teams to work and deploy independently of each other. For example, instead of having 100 developers working on a single app, you have 12 teams of 8 working on one microservices each. But you have to be careful how you structure your teams, since that is going to drive the overall design of the system. (See Conwayś law) In real life many companies break their apps in too many small microservices and you end up with a "distributed ball of mud". Which is way worst than the original monolith.
