If you have the problem for which microservices are the better solution (as you describe in your example), great! But I have seen people try to build a solution using microservices "because this is the way to go". But this often trades the problems of commits and unit verification for problems of architecture. It can take a lot of work and skill to design a robust architecture using microservices and architectural bugs and failures can be a lot harder to debug, understand and resolve. Pick your poison.
