From Modular Monolith to Microservices (Incremental Architecture Evolution)

Summary

This video demonstrates how to extract a module from a modular monolith into a dedicated service by elevating logical boundaries to physical ones. It highlights that well-defined public APIs within the monolith are crucial for this transition. The practical takeaway is that while the core communication pattern remains similar, the underlying technology for inter-module communication must shift from method calls to network calls like HTTP when moving to a distributed system.
