Microservices Architecture
💡 Best for: Distributed systems with independent services.
✅ Key Concepts:

• Each microservice has its own database and handles a specific business capability.
• Services communicate via REST, gRPC, or messaging (Kafka, RabbitMQ).

📦 Example Microservices:
cpp
CopyEdit
com.example.reservation     // Reservation Service
com.example.flight          // Flight Management Service
com.example.payment         // Payment Processing Service
com.example.notification    // Notification Service (Kafka, Email, SMS)
🔹 Why use it?

• High scalability (each service can scale independently).
• Technology flexibility (different services can use different tech stacks).
• Resilient (if one service fails, others can continue).

🚨 Limitations:

• Complexity (distributed system challenges like network failures, data consistency).
• Requires DevOps skills (Kubernetes, Docker, CI/CD).
