A process is selected for movement from a current node to a new node, based on an inertia of the process. The inertia is a quantified measure of the impact resulting from the process being inaccessible while being moved. The inertia can take into account the number of current external connections to the process; the larger the number of current external connections is, the greater the inertia. The inertia can take into account the extent to which the process accepts external connections; the greater the extent to which the process accepts external connections is, the greater the inertia. The inertia can take into account the desired availability of the process; the greater the desired availability is, the greater the inertia. The inertia can take into account a specified quality of service of the process; the higher the specified quality of service is, the greater the inertia.
