Today, we've been diving deep into the world of modern software architecture, exploring how microservices have become a strategic imperative for businesses seeking agility and rapid innovation. We discussed their evolution from traditional monolithic systems, emphasizing core principles like independent operation, loose coupling, and alignment with business capabilities. While microservices offer incredible benefits in scalability and resilience, we also explored their inherent challenges as distributed systems, from network latency to data consistency. Finally, we looked at practical approaches to breaking down applications, including patterns like "decompose by business capability," "by subdomain" using Domain-Driven Design, and the "Self-Contained System" approach, all while considering the importance of incremental migration strategies like the Strangler Fig pattern
