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 functions of API Gateways, such as handling cross-cutting concerns like authentication, authorization, and logging. The tutorial also covers routing and aggregation of requests, and discusses design considerations and patterns for API Gateways, including gateway routing, aggregation, and offloading patterns.

What is the primary role of an API Gateway?

• To store data for microservices

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

• To directly connect clients to databases

• To replace microservices

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

• Protocol translation

• Data storage

• Load balancing

• Authentication

How do API Gateways handle cross-cutting concerns?

• By delegating them to the client

• By centralizing them within the gateway

• By embedding them into each microservice

• By ignoring them

What is one advantage of API Gateways in terms of microservice requests?

• They eliminate the need for microservices

• They slow down the response time

• They aggregate multiple requests into one response

• They increase the number of requests

Which pattern is NOT associated with API Gateways?

• Gateway caching pattern

• Gateway routing pattern

• Gateway aggregation pattern

• Gateway offloading pattern
