The size of may be changed to the size of the container 431 corresponding to four CPU cores. Similarly, based on the resource usage of the container, the size of the container 332 allocated to the virtual machine 322 is the size of the container 432 corresponding to two CPU cores, and the container allocated to the virtual machine 323 ( The size of 333 may be changed to the size of the container 433 corresponding to one CPU core.

Referring to FIG. 4 , in the step 230 of porting a container according to the embodiment, the amount of the first resource used by the first container 432 allocated to the first virtual machine 422 (eg, acquiring two CPU cores), the amount of second resources not used by the second container 431 allocated to the second virtual machine 421 among the resources occupied by the second virtual machine 421 ( For example, acquiring two CPU cores), determining whether to transplant the first container 432 by comparing the amount of the first resource with the amount of the second resource, and according to the determination result, the container cluster may include the step of porting the first container 432 from the first virtual machine 422 to the second virtual machine 421 using

The determination of whether to transplant according to the embodiment may correspond to the determination of transplanting when the amount of the first resource and the amount of the second resource are the same, and when the amount of the first resource is greater than the amount of the second resource, the determination not to transplant This may be the case, and when the amount of the first resource is less than the amount of the second resource, it may be determined whether to transplant according to a predetermined criterion. For example, when referring to FIG. 4 , since the amount of the first resource and the amount of the second resource are equal to two CPU cores, the first container 432 is transferred from the first virtual machine 422 to the second virtual machine 421 . A decision to transplant can be made.

According to an embodiment, the porting of the first container from the first virtual machine to the second virtual machine deletes the first container from the first virtual machine, and a size corresponding to the amount of the first resource in the second virtual machine.

As a result of monitoring the resource usage of the container according to an embodiment, if there is no resource used by the container among the resources occupied by the virtual machine, it may be identified as the virtual machine 522 to which the container is not allocated. 5 and 6 , the container cluster 540 may be changed to a container cluster 640 in which a virtual machine to which a container is not allocated is removed by the step of releasing the virtual machine 240 . According to an embodiment, as the virtual machine 522 is released in the step of releasing the virtual machine 240 , the occupation of the computing resources occupied by the virtual machine 522 may be released. The computing resources 601 to 606 released by the virtual machine may be used by the physical machine or may be occupied by the new virtual machine when a new virtual machine is created.

Referring to FIGS. 8 and 9 , the virtual machine 823 of FIG. 8 does not have an allocated container, so the step 240 of releasing the virtual machine may be performed. The virtual machine 823 is removed from the container cluster 840 by the step 240 of releasing the virtual machine according to the embodiment, so that the container cluster 940 of FIG. 9 includes only virtual machines excluding the virtual machine 823 . It can be done, and the virtual machine 823 can be released. In this case, the computing resources 901 to 906 occupied by the virtual machine 823 may be released by the virtual machine and used by the physical machine, and may be occupied by the new virtual machine when a new virtual machine is created. .
