Design Microservices Architecture with Patterns and Principles - Service-to-Service Communications Chain Queries

The video discusses the challenges of service communication in microservices, particularly when multiple HTTP calls are involved, leading to increased latency and reduced performance. It uses the example of placing an order to illustrate these issues. The video suggests two solutions: using asynchronous communication with message brokers and employing service aggregator patterns. These approaches aim to improve system performance, scalability, and availability by reducing the dependency on synchronous HTTP requests.

What is a potential issue when making multiple HTTP calls to microservices?

• Improved system performance

• Unmanageable project complexity

• Decreased latency

• Increased manageability

What is a consequence of using synchronous messaging patterns in microservices?

• Reduced system availability

• Enhanced performance

• Improved scalability

• Decreased latency

What is a potential risk if a middle service is down during synchronous communication?

• Reduced latency

• Increased system availability

• Improved client response time

• Unacceptable high latency

What is one proposed solution to handle communication challenges in microservices?

• Increasing the number of HTTP calls

• Using synchronous messaging patterns

• Implementing message broker systems

• Reducing the number of microservices

What is the role of a service aggregator pattern in microservices?

• To eliminate the need for message brokers

• To increase the number of HTTP requests

• To aggregate query operations in one gateway

• To decrease system latency
