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.

Describe the role of message brokers in asynchronous communication.

How can microservices utilize both synchronous and asynchronous communication?
