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 are the potential issues with synchronous messaging patterns in microservices?

How does increasing the number of HTTP requests affect system performance?

What happens if a step in the service call chain fails?
