  • Computing system and computing system management method
    Patent number: 8732312
    Abstract: A computing system includes: a plurality of computing machines and a load balancer configured to allocate computing processing to the plurality of computing machines. In the computing system, the plurality of computing machines executes the computing processing, each of the plurality of computing machines includes an execution instruction unit that instructs to execute one of garbage collection (GC) and restart of the computing machine. The computing machine, in an active state in which the computing processing is allowed to be executed, switches a state of another standby computing machine to an active state when the active computing machine is instructed to execute one of the GC and the restart of the computing machine, and starts one of the GC and the restart of the computing machine after the switching is completed.
