From my perspective the corporate obsession with microservices is a natural evolution from their ongoing obsession with Agile. One of the biggest consequences of Agile adoption I’ve seen has been the expectation of working prototypes within the first few months of development, even for large projects. For architects this could mean honing in on solutions in weeks that we would have had months to settle on in the past. Microservices are attractive in this context because they buy us flexibility without holding up development. Once we’ve identified the services that we’ll need, we can get scrum teams off and running on those services while working alongside them to figure out how they all fit together. Few other architectures give us that kind of flexibility.
All this is to say that if your current silver bullet introduces a unique set of problems, you shouldn’t be surprised if the solutions to those problems start to also look like silver bullets.
This is how it went down with Agile at my company 10 years ago, and some process certifications and database technologies before that. Based on what I’m hearing from upper management microservice are probably next.
