Design Microservices Architecture with Patterns and Principles - gRPC Usage in Microservices Communication

The video tutorial explains the use of GRPC in microservice communications, focusing on a shopping cart example. It highlights the need for synchronous communication for immediate responses and describes the roles of GRPC client and server components. The tutorial also covers the implementation of backend microservices, such as product and discount services, using GRPC. It emphasizes the importance of configuring GRPC endpoints for HTTP2 and compares synchronous and asynchronous communication patterns, recommending GRPC for high-performance direct communication.

What is the primary reason for using synchronous communication in the shopping cart microservice example?

• To enable offline processing

• To reduce server load

• To provide immediate responses

• To simplify the codebase

In the context of GRPC, what role does the shopping cart microservice play?

• It functions as a GRPC client

• It serves as a load balancer

• It acts as a GRPC server

• It operates as a database

Which protocol is essential for configuring GRPC endpoints?

• SMTP

• FTP

• HTTP/2

• HTTP/1.1

Why is GRPC considered a high-performance communication protocol?

• It uses HTTP/1.1

• It is based on HTTP/2 and Protocol Buffers

• It relies on XML

• It is compatible with all browsers

What is the main advantage of using GRPC for direct synchronous communication in microservices?

• It provides high performance and immediate responses

• It is easier to implement than REST

• It requires less bandwidth

• It supports asynchronous communication
