Design Microservices Architecture with Patterns and Principles - The Solution - API Gateway Patterns

The video tutorial explains the role of API Gateways as a single entry point between client applications and internal microservices. It highlights the key functions of API Gateways, such as handling cross-cutting concerns like authentication, authorization, and rate limiting. The tutorial emphasizes the importance of centralized management and routing, and introduces design considerations and patterns like gateway routing, aggregation, and offloading.

What is the primary role of an API Gateway?

• To function as a standalone application

• To replace all microservices

• To serve as a single point of entry for client applications

• To act as a database for microservices

Which of the following is NOT a function of an API Gateway?

• Load balancing

• Authentication

• Protocol translation

• Data storage

How do API Gateways handle cross-cutting concerns?

• By ignoring them

• By delegating them to the client

• By centralizing them within the gateway

• By integrating them into each microservice

What is one of the benefits of API Gateway routing?

• It allows for the aggregation of multiple microservice requests

• It increases the number of microservices

• It reduces the need for security measures

• It eliminates the need for client applications

Which pattern is NOT associated with API Gateways?

• Gateway routing pattern

• Gateway aggregation pattern

• Gateway encryption pattern

• Gateway offloading pattern
