Designing scalable microservices architecture involves defining clear service boundaries, establishing inter-service communication patterns, and implementing resilience strategies. This ensures distributed systems scale independently while maintaining robust performance and reliable communication.

Event-driven architecture uses message queues and event streams for asynchronous processing in distributed systems. You need it when decoupling services to achieve higher scalability, resilience, and real-time data propagation across independent backend components.

The best way to design API contracts is by clearly defining endpoints, request/response schemas, and versioning strategies. Expertly crafted RESTful, GraphQL, and gRPC APIs ensure clear communication between services and maintainable integrations.

Managing distributed transactions and security in backend systems requires applying distributed transaction patterns and security best practices. This ensures data consistency across microservices and protects API endpoints from unauthorized access.

You should not use microservices when application complexity is low, as distributed systems introduce overhead in inter-service communication, observability, and deployment. A monolithic backend architecture is often better for simple, tightly coupled functional requirements.
