What network protocols are used for microservice interaction in your architecture?

The following network protocols are often used for microservices interaction in architecture:

• HTTP/HTTPS — the most common protocol for REST APIs, easy to use and supported by all languages.
• gRPC — a protocol based on HTTP/2 with support for binary serialization, providing high performance and strict typing.
• AMQP (e.g., RabbitMQ) — a protocol for message exchange through brokers, used for asynchronous interaction.
• MQTT — a lightweight messaging protocol, often used in IoT.

The choice depends on performance requirements, reliability, and the type of interaction (synchronous or asynchronous).
