Design Microservices Architecture with Patterns and Principles - gRPC: High Performance Remote Procedure Calls

gRPC is an open-source remote procedure call system developed by Google, designed for high-performance service connections in distributed systems. It uses HTTP/2 for binary message transport and relies on Protocol Buffers to define service contracts, enabling cross-platform client and server bindings. gRPC is ideal for microservices and connecting mobile or browser clients to backend services. It allows developers to create efficient, language-independent services, simplifying service interactions and communication infrastructure setup.

What protocol does GRPC use to transport binary messages?

• HTTP/2

• SMTP

• HTTP/1.1

• FTP

What is the primary role of Protocol Buffers in GRPC?

• To encrypt messages

• To define service contracts

• To manage databases

• To handle user authentication

Which of the following is a feature of Protocol Buffers?

• It only supports Java

• It generates cross-platform bindings

• It is used for frontend development

• It is a database management tool

In which architecture is GRPC commonly used?

• Monolithic architecture

• Microservice architecture

• Client-server architecture

• Peer-to-peer architecture

How does GRPC simplify service interactions?

• By using a single programming language

• By requiring manual setup for each service

• By automatically generating communication code

• By eliminating the need for service contracts
