📐 Applying SOLID Principles in Microservices

SOLID principles help developers build robust, maintainable, and scalable microservices. Here's how they apply:

1. Single Responsibility Principle (SRP) ✅

Each microservice should have one responsibility and reason to change.

2. Open/Closed Principle (OCP) 💡

Microservices should be open for extension but closed for modification. Use abstractions for future changes.

3. Liskov Substitution Principle (LSP) ✅

Derived classes or microservices should be substitutable without breaking system behavior.

4. Interface Segregation Principle (ISP) 💡

Expose only relevant endpoints/interfaces per service; avoid fat interfaces that force clients to depend on unused methods.

5. Dependency Inversion Principle (DIP) ✅

High-level modules should not depend on low-level modules directly; use abstractions for decoupling and flexibility.

Conclusion

Applying SOLID principles in microservices ensures your architecture remains clean, modular, and maintainable as the system grows.

🔄 Distributed Transactions Deep Dive

Welcome back to The Code Hut Distributed Systems series! In this post, we’ll dive deeper into distributed transactions, advanced Saga patterns, and techniques to maintain consistency across microservices. Why Distributed Transactions Are Tricky In a distributed system, each service typically manages its own database. Coordinating multiple services to commit or roll back changes atomically is challenging because: Network failures can occur Partial failures can leave inconsistent state Global locking is expensive and reduces availability 1. Saga Pattern Deep Dive The Saga pattern breaks a transaction into a series of smaller, independent steps with compensating actions if something fails. Choreography: Services emit events that trigger the next step. Orchestration: A central coordinator tells each service what action to take next. 2. Example: Orchestrated Saga in Java // Orchestrator triggers a series of service calls public class OrderSagaOrche...
