AWS Serverless Microservices with Patterns and Best Practices - Microservices Communications

The video tutorial covers microservice communication types, focusing on synchronous and asynchronous methods. It explains the challenges of distributed systems and the importance of choosing the right communication protocol, such as HTTP, GRPC, or AMQP. Synchronous communication involves blocking client threads until a response is received, while asynchronous communication allows non-blocking operations using message brokers like Kafka and RabbitMQ. The tutorial also discusses different asynchronous models, including one-to-one and one-to-many, and highlights tools like AWS EventBridge for implementation.

What is a key challenge when transitioning to a microservice-based application?

• Increasing the size of each service

• Implementing a monolithic architecture

• Changing the communication mechanism

• Reducing the number of services

In synchronous communication, what happens after a client sends a request?

• The server sends a response without waiting

• The client waits for a response, blocking its thread

• The client continues its task immediately

• The client sends multiple requests simultaneously

Which protocol is commonly used for synchronous communication?

• AMQP

• HTTP

• FTP

• SMTP

How does asynchronous communication differ from synchronous communication?

• The server blocks the client thread

• The client waits for a response

• The client uses HTTP protocols

• The client does not wait for a response

What is a characteristic of one-to-many asynchronous communication?

• A single producer and single receiver

• Multiple producers and a single receiver

• A single producer and no receivers

• Multiple receivers for each request
