how to approach transforming a monolithic to microservices?

1 Answers

- Align the team knowledge and management method: Microservices architectures require a high coordination of knowledge and skills and need organizations that allow this coordination. - Divide and conquer: Either split the presentation layer from the business logic and data access layers or extract a module from existing monolithic app. A strangler application is a good approach to start with. - Test, and try again: One of the benefits of microservices is it's easier for incremental improvement, building a CI/CD solution along with it will save you time for testing and perfect it.
