Design Microservices Architecture with Patterns and Principles - Microservices Communication Types - Synchronous or Asyn

The video tutorial explains the two main types of communication in microservices: synchronous and asynchronous. Synchronous communication involves the client waiting for a response from the server, typically using HTTP or GRPC protocols. Asynchronous communication, on the other hand, allows the client to send requests without waiting for a response, often using AMQP protocols and message broker systems like Kafka. The tutorial further explores asynchronous models, including one-to-one and one-to-many implementations, and discusses how microservices can use a combination of these communication styles to build efficient architectures.

What are the two main axes used to classify communication types in microservices?

• Direct and Indirect

• Synchronous and Asynchronous

• Static and Dynamic

• Linear and Non-linear

Which protocol is commonly used for synchronous communication in microservices?

• FTP

• SMTP

• HTTP

• AMQP

In synchronous communication, what happens to the client thread after sending a request?

• It sends another request

• It continues processing other tasks

• It waits for a response

• It terminates immediately

What is a key characteristic of asynchronous communication?

• The client does not block a thread

• The client waits for a response

• The client sends requests in batches

• The client uses HTTP protocol

Which protocol is popular for asynchronous communication?

• SMTP

• AMQP

• FTP

• HTTP

In a one-to-one queue model, how many producers and receivers are there?

• Multiple producers and multiple receivers

• One producer and multiple receivers

• Multiple producers and one receiver

• One producer and one receiver

What is the main advantage of using a one-to-many topic model in asynchronous communication?

• It allows for synchronous responses

• It supports multiple receivers for each message

• It requires less bandwidth

• It simplifies the client-server architecture
