Design Microservices Architecture with Patterns and Principles - Problem: Handle Millions of Events Across Microservices

What is the primary problem identified in the current architecture?

• Poor network connectivity

• Insufficient database storage

• Handling millions of events across microservices

• Lack of user interface design

Which pattern is used in the event-driven approach for order fulfillment?

• Observer Pattern

• Singleton Pattern

• Choreography-based SAGA Pattern

• Factory Pattern

What is a key consideration when multiple subsystems must process the same event?

• Real-time processing with minimum latency

• Data redundancy

• User authentication

• Network bandwidth

What is a major challenge in managing high-volume events in microservices?

• Decoupled communication for thousands of microservices

• Limited user access

• High cost of implementation

• Complex user interfaces

What solution is proposed for handling high-volume events in microservices?

• Centralized database architecture

• Client-server model

• Monolithic application design

• Event-driven architecture
