Resource dynamic allocation device, resource dynamic allocation program, resource dynamic allocation system, and resource dynamic allocation method

A non-transitory computer-readable storage medium storing

• a resource dynamic allocation program causing a computer to execute processing comprising:
• acquiring a multithreaded application process initialized at a time of activation, a thread which is included in the multithreaded application process and to which a possible physical resource on a physical server is allocated, and allocation information of the physical resource allocated to the thread;
• and
• freezing all threads of the initialized multithreaded application process and freezing the thread or unfreezing the thread in accordance with any one of transfer traffic, a resource load, and a load of the multithreaded application process.

A resource dynamic allocation system comprising:

• a resource dynamic allocation device that dynamically allocates a resource;
• and
• a controller that determines scale-in and scale-out of the resource, wherein
• the resource dynamic allocation device includes a processor and a memory storing instructions that, when executed by the processor, cause the resource dynamic allocation device to perform operations of:
• a thread ID acquisitor that acquires a multithreaded application process initialized at a time of activation, a thread which is included in the multithreaded application process and to which a possible physical resource on a physical server is allocated, and allocation information of the physical resource allocated to the thread, and
• a resource recorder/allocator that freezes all threads of the initialized multithreaded application process and freezes the thread or unfreezes the thread in accordance with any one of transfer traffic, a resource load, and a load of the multithreaded application process.
