The most effective methods for data exchange between microservices are:
-
HTTP REST API — a simple and widely used method, suitable for synchronous interaction. Uses JSON or XML for data transfer.
-
gRPC — a high-performance protocol supporting binary format and contract description via protobuf. Suitable for microservices requiring low latency.
-
Messaging through brokers (RabbitMQ, Kafka) — asynchronous exchange, increases resilience and scalability. Microservices publish and subscribe to events.
-
GraphQL — allows clients to request only the necessary data, reducing redundancy.
The choice depends on requirements for latency, reliability, and system complexity. Often, synchronous (REST/gRPC) and asynchronous (messaging) approaches are combined.
