“In Orchestration, we rely on a central system to control and call other Microservices to complete a task. In Choreography, each Microservice works like a State Machine and reacts based on the input from other parts. Orchestration is a tightly coupled approach for integrating Microservices. Whereas, Choreography is a loose coupling approach. Choreography based systems are more flexible and easy to change than Orchestration based systems. Orchestration is often implemented by synchronous calls. Choreography is implemented by asynchronous calls. The synchronous calls are much simpler compared to asynchronous communication.”
