METHOD, DEVICE AND COMPUTER PROGRAM FOR DYNAMICALLY ALLOCATING RESOURCES OF A CLUSTER TO THE EXECUTION OF PROCESSES OF AN APPLICATION

摘要

The invention is aimed in particular at the dynamic allocation of at least one resource of a plurality of resources of a set of resources of a cluster, the resources of said plurality of resources being reserved for the execution of processes of an application. For these purposes, at least one virtual machine is created (305) in at least one resource of said plurality of resources, said at least one virtual machine offering characteristics similar to those of said at least one resource. When at least one currently executing process of said application, which process can be downscaled into at least one other process, is identified, at least one available resource comprising at least one unused virtual machine is identified from among said reserved resources. Said at least one process that can be downscaled is then downscaled (325), at least one process resulting from said downscaling being executed by an unused virtual machine of said at least one identified resource.
