Method and system for differentiating QoS in inter-microservice communication

A method of differentiating quality of service (QOS) in inter-microservice communication, the method comprising:

• generating a QoS-aware path for guaranteeing quality of service between a sending microservice and a receiving microservice before execution of inter-microservice communication;
• registering information on the QoS-aware path between the sending and receiving microservices;
• in response to determining that guaranteeing the quality of service of a message received from the sending microservice is necessary, identifying the QoS-aware path between the sending microservice and the receiving microservice from the registered information on the QoS-aware path;
• and
• processing the inter-microservice communication to allow the message to be transferred to the receiving microservice through the identified QoS-aware path.

An apparatus for ensuring quality of service (QOS) between microservices, the apparatus comprising:

• a communication processing unit;
• a service registration unit operatively connected to the communication processing unit;
• and
• a network processing unit operatively connected with the service registration unit,
• wherein the network processing unit:
• upon a request from the communication processing unit, generates a QoS-aware path to ensure QoS between a sending microservice and a receiving microservice before execution of inter-microservice communication;
• registers information on the QoS-aware path between the sending and receiving microservices;
• and
• when guaranteeing the quality of service of a message received from the sending microservice is necessary, identifies the QoS-aware path between the sending microservice and the receiving microservice from the registered information on the QoS-aware path, and processes inter-microservice communication to allow the message to be transferred to the receiving microservice through the identified QoS-aware path.
