Synchronous communication
Microservices communicate in various ways, each serving different needs based on the system’s architecture and requirements. Here, we will explore synchronous communication, a foundational aspect of microservices architecture, where services interact directly and expect an immediate response. It is characterized by its request-response nature, making it suitable for scenarios requiring instant feedback and real-time data exchange.
Synchronous communication often leads to tighter coupling between services. Each service needs to know the endpoint of the service it communicates with, creating a direct dependency.
A key advantage of synchronous communication is the ability to provide immediate feedback. This is crucial for operations requiring real-time confirmation or data retrieval.
RESTful APIs and GraphQL are typical examples of synchronous communication with microservices. GraphQL allows clients to request specific data, which is suitable...
