Design Microservices Architecture with Patterns and Principles - API Gateway Pattern

The video tutorial explains the API Gateway pattern, which serves as a single entry point for client applications, managing routing to internal microservices and handling cross-cutting concerns like authentication and rate limiting. It compares the API Gateway to the Facade pattern in Object-Oriented design, highlighting its role as a reverse proxy. The tutorial emphasizes the importance of avoiding a single point of failure by splitting the API Gateway into multiple services based on business boundaries. It concludes with a caution against using a single API Gateway for all microservices, recommending segregation to manage complexity effectively.
