What is Microservice Communication?
Turkish: Mikroservis İletişimi
Microservice communication is how independent services exchange data and commands through REST, gRPC, events, or message queues.
What is Microservice Communication?
Microservice communication is the way independently deployed services request data, send commands, or publish events to one another. The chosen communication model directly affects latency, reliability, and operational complexity.
Communication Models
In synchronous communication, one service sends a REST or gRPC request to another service and waits for a response. This is easy to understand for simple queries, but it introduces timeout, retry, and cascading-latency risks. In asynchronous communication, a service publishes an event or sends work through a message queue, allowing the receiver to process it later even after a temporary outage.
Design Considerations
Service contracts, versioning, idempotency, correlation IDs, distributed tracing, circuit breakers, and backpressure are part of the communication design. Calling another service for every small operation can make the network the bottleneck. In some cases, local read models or event-based synchronization are healthier choices.
A microservice architecture only becomes manageable when service boundaries and communication rules are explicit.
