Answer from AI
Interaction between microservices in a modern application is usually implemented in the following ways:
-
HTTP/REST API — the most common method, where microservices communicate via HTTP protocol using RESTful interfaces. Easy to implement and debug.
-
gRPC — a high-performance remote procedure call protocol that uses Protocol Buffers for serialization. Suitable for internal microservice communication.
-
Messages through brokers (Message Brokers) — asynchronous interaction via message queues (RabbitMQ, Kafka, Redis Streams). Allows unloading services and increasing fault tolerance.
-
Event-driven architecture — microservices exchange events, reacting to each other's state changes.
-
GraphQL — sometimes used to aggregate data from multiple microservices in a single request.
The choice of method depends on requirements for performance, reliability, and system complexity.
