In this chapter, we discussed different factors that can be used to identify and isolate microservices at a high level. We also discussed the various characteristics of a good service. Talking about DDD, we saw what its importance is in the context of microservices.
Further, we analyzed how we can correctly achieve vertical isolation of microservices through various parameters in detail. While we tried to draw upon our previous understanding of the challenges posed by a monolithic application and its solution in microservices, we saw that we can use factors such as module interdependency, technology utilization, and team structure to identify seams and perform the transition from a monolithic architecture to microservices in an organized manner.
It became apparent that the database can pose a clear challenge in the process. However, we identified how we can still perform this with a simple strategy and the possible approaches to do this. We then discussed that with the foreign keys...
