Abstract

An information processing system includes one or more virtual machines, a container scaling apparatus, a virtual-machine scaling apparatus, a calculating unit, and a reflecting unit. The container scaling apparatus performs autoscaling of a container that runs on the one or more virtual machines. The virtual-machine scaling apparatus performs autoscaling of the virtual machines in accordance with a difference in a necessary number of virtual machines and a number of virtual machines that are currently running. The calculating unit calculates, from a necessary number of containers calculated by the container scaling apparatus, a number of virtual machines that is necessary to cause the necessary number of containers to run thereon. The reflecting unit reflects the number calculated by the calculating unit to the necessary number of virtual machines to be used by the virtual-machine scaling apparatus.

Claims

1. An information processing system comprising:

one or more virtual machines; and

a hardware processor and a memory, the hardware processor configured to operate as;

a container scaling apparatus that performs autoscaling of a container that runs on the one or more virtual machines;

a virtual-machine scaling apparatus that performs autoscaling of the virtual machines in accordance with a difference in a necessary number of virtual machines and a number of virtual machines that are currently running;

a calculating unit that calculates, from a necessary number of containers calculated by the container scaling apparatus, a number of virtual machines that is necessary to cause the necessary number of containers to run thereon; and

a reflecting unit that communicates the number calculated by the calculating unit as the necessary number of virtual machines to be used by the virtual-machine scaling apparatus,

wherein the calculating unit calculates the necessary number of virtual machines by multiplying, by a buffer ratio of greater than 1, a number obtained by multiplying, by the necessary number of containers, a resource use ratio indicating a ratio of resources to be used by one of the containers to resources of one of the virtual machines.

2. An autoscaling association apparatus comprising:

a hardware processor and a memory, the hardware processor configured to operate as;

a calculating unit that calculates, from a necessary number of containers calculated by a container scaling apparatus, a number of virtual machines that is necessary to cause the necessary number of containers to run thereon; and

a reflecting unit that communicates the number calculated by the calculating unit as a necessary number of virtual machines to be used by a virtual-machine scaling apparatus that performs autoscaling of the virtual machines in accordance with a difference between the necessary number of virtual machines and a number of virtual machines that are currently running,

wherein the calculating unit calculates the necessary number of virtual machines by multiplying, by a buffer ratio of greater than 1, a number obtained by multiplying, by the necessary number of containers, a resource use ratio indicating a ratio of resources to be used by one of the containers to resources of one of the virtual machines.

3. The autoscaling association apparatus according to claim 2, wherein the calculating unit calculates the necessary number of virtual machines by using a resource use ratio and the necessary number of containers, the resource use ratio indicating a ratio of resources to be used by one of the containers to resources of one of the virtual machines.

4. A non-transitory computer readable medium storing a program causing a computer to execute a process for autoscaling association, the process comprising:

calculating, from a necessary number of containers calculated by a container scaling apparatus, a number of virtual machines that is necessary to cause the necessary number of containers to run thereon; and

reflecting the number obtained through the calculating to a necessary number of virtual machines to be used by a virtual-machine scaling apparatus that performs autoscaling of the virtual machines in accordance with a difference between the necessary number of virtual machines and a number of virtual machines that are currently running,

wherein the calculating of the necessary number of virtual machines occurs by multiplying, by a buffer ratio of greater than 1, a number obtained by multiplying, by the necessary number of containers, a resource use ratio indicating a ratio of resources to be used by one of the containers to resources of one of the virtual machines.
