a redundancy group is configured with the plurality of virtual machines or containers which serve as the storage controllers located on different nodes,

a processing as a storage controller is taken over by the virtual machine or container which becomes the storage controller in the same redundancy group, when a failure occurs in the one node of the plurality of nodes,

comparing, via the management unit, the upper limit of the CPU amount of the node where the virtual machine or container which takes over the processing is placed with the total value of the first CPU amount, the second CPU amount, and the third CPU amount, and deploys the virtual machine or container which runs the application on the node when the total value of the CPU amount falls within the upper limit of the CPU amount of the node, and deploying the virtual machine or container which runs the application on the node on another node when the total value exceeds the upper limit.

3. The resource allocation method according to claim 2 , wherein

when there is no node to be an allocation destination of a virtual machine or volume based on the use state of the computer resource, any of the virtual machine, the container, the volume, or the storage controller on a first node of the plurality of nodes is migrated to a second node, so that the first node is set as the allocation destination of the virtual machine or the volume.

4. The resource allocation method according to claim 1 , wherein the

use state of the computer resource includes at least one of:

a use state of a storage capacity configured by the storage device in each of the nodes;

a use state of a CPU in each of the nodes;

a use state of memory in each of the nodes; and

a use state of a network bandwidth.

5. A resource allocation system which determines allocation of at least one of a virtual machine, a container, or a volume in a system of a hyperconverged infrastructure environment, the resource allocation system comprising:

a plurality of nodes, each node comprising:

at least one of a virtual machine and a container serving as a storage controller which operates a storage operating system (OS) and controls an input/output (I/O) for reading and writing of data to and from a volume serving as a data storage area;

a computer resource comprising:

a CPU configured to process data,

a memory; and

a storage device configured to store a program, control information and the data,

wherein at least one node of the plurality of nodes comprises a management unit,

wherein a fourth node of the plurality of nodes includes a first storage controller, a first volume, and a first drive, in which the first storage controller processes an JO request for the volume from the virtual machine and writes data to the first drive,

wherein a fifth node of the plurality of nodes includes a second storage controller, a second volume, and a second drive, in which the second storage controller operates as a redundancy destination storage controller of the first storage controller, receives redundant data from the first storage controller, and writes redundant data to the second drive,

wherein each of the plurality of nodes manages a computer resource configured to write the redundant data in addition to a use state of the computer resource shared by the virtual machine and the storage controller operating on each of the nodes, and

wherein, when a failure occurs in the node on which the virtual machine or container that operates the application and the virtual machine or the container that operates as the storage controller processing the JO from the virtual machine or container, each node if the plurality of nodes calculates a first CPU amount used by a virtual machine or container, which operates as a newly created or moved candidate application,

wherein each node calculates a second CPU amount used by the virtual machine or container which operates as the storage controller, based on the IO amount and redundancy scheme of the virtual machine or the container running as the application,

wherein each node of the plurality of nodes calculates a third CPU amount used by the virtual machine or container of the existing application, and

wherein the management unit determines, based on the first CPU amount, the second CPU amount, and the third CPU amount use state, a node having the calculated storage area capacity of the storage device and a CPU amount equal to the sum of the first CPU amount, the second CPU amount, and the third CPU amount as an allocation destination node of a virtual machine, a container, or a volume without exceeding an upper limit of the computer resource of the allocation destination node.
