Design Microservices Architecture with Patterns and Principles - Service Aggregator Pattern - Microservices Communicatio

The video tutorial explains the service aggregator pattern, which minimizes service-to-service communication by receiving a request from a client or API gateway, dispatching it to multiple backend microservices, and combining the results into a single response. This pattern reduces communication overhead and centralizes logic, making it useful in e-commerce applications. An example of its implementation is the Add Item Aggregator microservice, which orchestrates operations involving product, shopping cart, and pricing services. The pattern reduces direct dependencies among microservices, leading to reduced coupling and improved architecture.
