Information processing apparatus, information processing system, and method of controlling information processing apparatus

An information processing system comprising a plurality of information processing apparatuses, wherein one or more of the information processing apparatuses including:

• a logic circuit provided with a processing function that performs processing of a microservice and a communication interface that is coupled to a network;
• a service mesh functional circuit that realizes a service mesh;
• and
• a pseudo application that is coupled to the logic circuit via the service mesh functional circuit and that does not have a microservice processing function,
• wherein the logic circuit starts, based on reception of request data for a data plane communication from a first other information processing apparatus by the communication interface, processing of a service that uses the request data by the processing function, generates a pseudo request for a control plane communication, transmits the generated pseudo request to the pseudo application, and transmits a processing completion notification to the pseudo application based on completion of the processing of the service by the processing function,
• the pseudo application transmits a pseudo response to the logic circuit based on reception of the processing completion notification after reception of the pseudo request,
• when detecting the pseudo response transmitted from the pseudo application to the logic circuit, the service mesh functional circuit rewrites destination information included in the pseudo response and transfers the pseudo response in which the destination information has been rewritten to the logic circuit, and
• the logic circuit generates, based on reception of the pseudo response that includes the rewritten destination information, request data for a next data plane communication while including the rewritten destination information in data after the processing of the service, and transmits the generated request data from the communication interface to a second other information processing apparatus.

A method of controlling an information processing apparatus that employs a microservice architecture and includes a logic circuit provided with a processing function that performs processing of a microservice and a communication interface that is coupled to a network, a service mesh functional circuit that realizes a service mesh, and a pseudo application that is coupled to the logic circuit via the service mesh functional circuit and that does not have a microservice processing function, wherein the method comprising:

• the logic circuit starts, based on reception of request data for a data plane communication from a first other information processing apparatus by the communication interface, processing of a service that uses the request data by the processing function, generates a pseudo request for a control plane communication, transmits the generated pseudo request to the pseudo application, and transmits a processing completion notification to the pseudo application based on completion of the processing of the service by the processing function;
• the pseudo application transmits a pseudo response to the logic circuit based on reception of the processing completion notification after reception of the pseudo request;
• when detecting the pseudo response transmitted from the pseudo application to the logic circuit, the service mesh functional circuit rewrites destination information included in the pseudo response and transfers the pseudo response in which the destination information has been rewritten to the logic circuit;
• and
• the logic circuit generates, based on reception of the pseudo response that includes the rewritten destination information, request data for a next data plane communication while including the rewritten destination information in data after the processing of the service, and transmits the generated request data from the communication interface to a second other information processing apparatus.
