 Microservices vs Monolithic Architecture Here’s a clear side-by-side comparison between Microservices and Monolithic architectures — from a system design and engineering perspective: Aspect Monolithic Architecture Microservices Architecture Definition A single, tightly coupled codebase where all modules run as one unified application A collection of small, independent services that communicate over the network (e.g., HTTP, gRPC) Codebase Single repository/project Multiple repositories or modular projects per service Deployment Deployed as one unit (e.g., one WAR, JAR, EXE) Each service is deployed independently Scalability Vertical scaling (scale entire app) Horizontal scaling (scale services independently based on load) Technology Stack Generally a unified stack (e.g., Java/Spring, .NET)...

 Event-Driven Architecture (EDA) vs Event Sourcing Pattern vs  Domain-Driven Design (DDD)  Here’s a clear point-by-point comparison of Event-Driven Architecture (EDA) , Event Sourcing Pattern , and Domain-Driven Design (DDD) in a tabular format: Aspect Event-Driven Architecture (EDA) Event Sourcing Pattern Domain-Driven Design (DDD) Definition Architecture style where components communicate via events Pattern where state changes are stored as a sequence of events Software design approach focused on complex domain modeling Primary Purpose Loose coupling and asynchronous communication Ensure complete audit and ability to reconstruct state from events Align software with business domain and logic Data Storage Not the focus – events trigger actions, state stored in services Event store maintains append-onl...
