Design Microservices Architecture with Patterns and Principles - Problem: Client Apps Have Different UI Requirements

The video discusses the challenges faced in designing an ecommerce application using microservices, particularly in meeting different UI requirements for web and mobile clients. The current architecture requires complex client-side logic to format data, leading to maintenance difficulties and high resource usage. The solution proposed is the Back End for Front End (BFF) pattern, which moves some frontend logic to an intermediate API gateway layer, simplifying client-side code and improving data representation.

Explain how the BFF API gateway layer functions in the context of the ecommerce application.

What are the benefits of implementing the BFF pattern in the ecommerce architecture?
