Information processing system, information processing method, and information processing apparatus to instruct generation and destruction of a plurality of application containers

An information processing system comprising a master apparatus configured to instruct generation and destruction of a plurality of application containers that operate in a plurality of node apparatuses, respectively, and a route control apparatus configured to control routing among the plurality of node apparatuses, wherein

• the master apparatus comprises a first processor configured to execute:
• receiving a first message requesting generation or destruction of an application container among the application containers that is in a first node apparatus among the plurality of node apparatuses;
• and
• transmitting, when receiving the first message, a second message showing that a configuration of the plurality of application containers has changed, to the route control apparatus;
• and
• the route control apparatus comprises a second processor configured to, when receiving the second message, execute generating route information, for each combination of node apparatuses among the plurality of node apparatuses in which application containers are present, comprising optimal communication routes among the plurality of application containers based on stored container information.
