Service meshes play an important role in the communication and coordination of microservices. Service meshes are used to coordinate the communication and coordination among microservices, allowing them to work together to form a larger application. 

A service mesh provides to manage communications between the individual services in a microservice-based system.

 The service mesh decouples the network logic from the application or business logic of each microservice so that it can be implemented and managed consistently across the whole system.
