Design Microservices Architecture with Patterns and Principles - Problem: Inter-Service Communication Makes Heavy Load o

The video tutorial addresses issues with the current architecture and explores designing synchronous APIs for microservices, focusing on public and backend APIs. It highlights the importance of network performance in backend APIs and discusses inter-service communication challenges. A use case involving shopping cart microservices is presented to illustrate these concepts. Best practices, such as using REST APIs for public communication and GRPC for inter-service communication, are recommended. The tutorial concludes with a discussion on GRPC's scalability and technology-agnostic nature.

What is the primary focus when designing synchronous APIs for microservices?

• Using JSON for all communications

• Identifying architecture problems

• Improving network performance

• Ensuring all APIs are public

Which protocol is recommended for public APIs to ensure easy client communication?

• GRPC

• SOAP

• FTP

• RESTful APIs

Why is JSON preferred for public API communication?

• It is faster than other formats

• It requires less bandwidth

• It is human-readable and easy to check

• It is binary and compact

What is a major challenge of inter-service communication in backend APIs?

• Lack of security

• High network traffic

• Incompatibility with REST

• Difficulty in serialization

Which protocol is suggested for efficient inter-service communication?

• HTTP

• SMTP

• FTP

• GRPC
