Microservices Architecture: Designing Scalable and Resilient Systems

This article explains microservices from an engineering-first perspective, focusing on why they exist, how they work, and where they fail. It covers core principles, service communication, data ownership, deployment, resilience patterns, and observability. Emphasis is placed on real trade-offs, helping readers understand when microservices are the right choice—and when a well-designed monolith is smarter.
