Design Microservices Architecture with Patterns and Principles - Design and Evaluate: Microservices Architecture with AP

The video tutorial covers microservice architecture with a focus on API Gateway design. It discusses communication patterns, including HTTP, GraphQL, gRPC, and WebSocket, and explores various API Gateway patterns like routing, aggregation, and offloading. The implementation of an API Gateway in an ecommerce application is detailed, highlighting its role in handling client requests and providing abstraction over backend microservices. The tutorial evaluates the benefits and drawbacks of using a single API Gateway, such as reduced network traffic and potential bottlenecks. Best practices for API Gateway usage, including splitting it into multiple services, are also discussed.

Which of the following is NOT a communication protocol mentioned in the introduction section?

• gRPC

• GraphQL

• SOAP

• HTTP-based APIs

What is one of the main roles of an API Gateway in a microservice architecture?

• To replace microservices with monolithic architecture

• To directly connect clients to each microservice

• To store data for microservices

• To handle client requests and provide a single entry point

How does the API Gateway reduce communication between client and backend microservices?

• By eliminating the need for client requests

• By aggregating multiple microservices into a single client request

• By directly connecting clients to databases

• By caching all client requests

What is a potential drawback of using a single API Gateway?

• It simplifies the architecture

• It can become a single point of failure

• It enhances security

• It reduces network traffic

What is a recommended best practice for managing API Gateways?

• Combining API Gateway with monolithic architecture

• Using a single API Gateway for all services

• Splitting the API Gateway into multiple smaller services

• Avoiding the use of API Gateways
