Object migration in non-monolithic distributed applications

Object migration is usually applied to optimize distributed monolithic systems. We investigate the effects of using object migration in cooperative systems which consist of autonomous, independently developed components. We show that the use of migration policies which are set up with only one component in mind can have detrimental effects on the overall performance. To avoid this without changing the internal structure of the components, we introduce two novel approaches: transient placement and reduction of attachment-transitiveness. The effects of these modifications are evaluated by simulation.
