Server selection device, server selection method, and server selection program
If it is determined that the performance requirements with respect to a server have throughput equal to or greater than a first threshold value or have latency equal to or smaller than a second threshold value, then a server selection device selects a bare metal. If the performance requirements do not have the throughput equal to or greater than the first threshold value and do not have the latency equal to or smaller than the second threshold value, when the functional requirements with respect to the server need the OS either to be an OS other than a predetermined OS, the server selection device selects a virtual machine; and, when the functional requirements with respect to the server neither need the OS to be an OS other than a predetermined OS, the server selection device selects a container.
