Design your Cloud Microservices Apps the DDD way (Hexagonal Architecture)

This write-up discusses the use of domain-driven design & SOLID principles in designing the structure of Microservices, with a focus on clean architecture practices for cloud-native applications. The author highlights the practices currently in use & presents possible solutions in alignment with DDD, SOLID principles, & the Hexagonal architecture. The aim is to make the code robust, maintainable, understandable & extendable by keeping all the business logic & models in a single place & everything else dependent on it. By inverting dependencies, the code becomes more extensible, with added features while avoiding the ripple effect due to coupling. This article is a must-read for Microservices enthusiasts looking to optimize their code structure.
