Design Microservices Architecture with Patterns and Principles - Main Features of API Gateway Pattern

The video tutorial explains the API Gateway pattern, highlighting its benefits such as reverse proxy and routing, abstraction of internal operations, request aggregation, and handling cross-cutting concerns. API Gateway acts as a reverse proxy, routing client requests to internal microservices, and provides abstraction, reducing the need for client updates when backend changes occur. It aggregates multiple service requests into a single client request, minimizing communication overhead. Additionally, it centralizes cross-cutting functionalities like authentication, authorization, and load balancing, enhancing system resilience and efficiency.
