One of the main reasons to design microservices is that they enforce strong module boundaries. However, the cons of microservices are so huge that it’s like chopping off your right hand to learn to write with the left one; there are more manageable (and less painful!) ways to achieve the same result.
Even since the microservices craze started, some cooler heads have prevailed. In particular, Oliver Drotbohm, a developer on the Spring framework, has been a long-time proponent of the moduliths alternative. The idea is to keep a monolith but design it around modules.
