🏗️ Modern Architecture Patterns — From DDD to Event-Driven Systems
Modern systems rely on microservices and APIs to deliver flexibility, scalability, and fault isolation. Understanding the patterns behind service communication and integration is essential for designing robust distributed architectures. 🌍 1. Principles of Microservices 🧩 Microservices decompose a system into independent, deployable components that communicate through APIs or events. 🚀 Single Responsibility: Each service focuses on one domain area (e.g., Orders, Payments). ⚡ Autonomous Deployment: Teams can deploy independently. 🔁 Resilience & Scalability: Isolated failures and fine-grained scaling. 2. API Communication Patterns 🌐 Microservices can communicate synchronously via REST/gRPC or asynchronously via events. 🌍 REST: HTTP-based, stateless, simple to use. ⚙️ gRPC: High-performance binary protocol (Protobuf), great for internal service-to-service calls. 📬 Event-driven: Asynchronous messaging decouples producers and consumers. // ...
