Can you list the main methods of interaction between microservices?

The main methods of interaction between microservices include:

• HTTP/REST API — the most common way, where services communicate via HTTP requests using REST architecture.
• gRPC — a high-performance remote procedure call protocol that uses Protocol Buffers for serialization.
• Message Brokers — message exchange through queue systems like RabbitMQ, Kafka, enabling asynchronous interaction.
• GraphQL — allows clients to request exactly the data they need, often used to aggregate data from multiple microservices.

An example of a simple HTTP request in Python using the requests library:

import requests
response = requests.get('http://microservice/api/data')
if response.status_code == 200:
    data = response.json()
    print(data)
