How is data exchanged between microservices in your project?

Data exchange between microservices is usually carried out through:

• HTTP/REST API — the most common method, where services communicate via the HTTP protocol, exchanging JSON or XML.
• Message Queues — for example, RabbitMQ, Kafka, where services publish and subscribe to events, ensuring asynchronous communication.
• gRPC — a high-performance protocol using protocol buffers for data serialization.

In my project, REST API is most often used for synchronous requests and Kafka for event-driven communication, which helps to unload services and increase fault tolerance.
