Design Microservices Architecture with Patterns and Principles - Problem: Service-to-Service Communications Chain Querie

The video tutorial discusses the challenges of inter-service communication in microservices, focusing on the chain query problem that arises when multiple microservices are involved in HTTP calls, leading to increased latency and performance issues. The tutorial explores synchronous solutions, particularly the service aggregator pattern, to address these challenges in the context of an e-commerce application.

What is the main problem identified in inter-service communication for microservices?

• Chain queries between services

• High development cost

• Data redundancy

• Lack of security

How do chain queries affect the performance of a microservices-based application?

• They increase latency

• They enhance security

• They reduce latency

• They improve data consistency

Which of the following is NOT a consequence of increased latency due to chain queries?

• Improved scalability

• Decreased performance

• Reduced availability

• Increased resource usage

What is one synchronous solution to address the chain query problem in microservices?

• Implementing a service mesh

• Increasing server capacity

• Using asynchronous messaging

• Developing aggregator microservices

What pattern is suggested to handle aggregate query operations in microservices?

• Service mesh pattern

• Service aggregator pattern

• Event sourcing pattern

• Circuit breaker pattern
