Design Microservices Architecture with Patterns and Principles - Microservices Synchronous Communications and Best Pract

The video tutorial discusses synchronous communication in microservices, focusing on HTTP and GRPC protocols. It explains the design of APIs using these protocols, emphasizing the importance of well-defined API design for both external and internal communications. The tutorial also covers different communication protocols like REST, GRPC, GraphQL, and WebSocket, highlighting their use cases and benefits in microservices architecture.

Which protocol is primarily used for synchronous communication in microservices?

• SMTP

• HTTP

• SNMP

• FTP

What is the main advantage of using GRPC for internal microservice communication?

• It offers better performance than REST.

• It is easier to implement than REST.

• It allows for real-time communication.

• It is more secure than REST.

Why is REST preferred for external communication in microservices?

• It allows for explicit visibility of payloads.

• It is faster than GRPC.

• It supports binary data formats.

• It is the only protocol supported by microservices.

What is a key focus when designing APIs for microservices?

• Avoiding the use of REST.

• Ensuring they are well-defined.

• Making them as complex as possible.

• Using only one type of protocol.

In the context of microservices, what is the role of GraphQL?

• To enhance security features.

• To replace HTTP protocols.

• To provide a flexible data query language.

• To handle real-time communication.
