I’ve been pretty invested in helping organizations with their cloud-native journeys for the last five years. Modernizing and improving a team (and eventually an organization’s) velocity to deliver software-based technology is heavily influenced by it’s people, process and eventual technology decisions. A microservices approach may be appropriate when the culmination of an application’s architecture has become a bottleneck (as a result of the various people/process/tech factors) for making changes and “going faster”, but it’s not the only approach.
Microservices is not THE “utopian application architecture”. I’ve written in the past how I didn’t think many teams would be able to pull it off, how there are “hard parts” to getting it working, and even heads up about some technology that might be beneficial to your efforts in the long run. FWIW I even wrote a book on the topic.
