A method and a device are disclosed for operating a data processing network which includes a plurality of geographically spaced-apart data centers and a large number of client computers, data being transmittable between each of the client computers and at least to one of the data centers, wherein one or more virtual servers is operateable in each of the data centers. According to at least one embodiment, access data is collected including information on geographical location of the client, geographical location of the virtual servers and the degree of utilization of the virtual servers. The access data collected is analyzed and, using the result of analysis, a migration plan, which is improved with respect to the mean latency, is created for the deployment of the virtual servers among the data centers. The virtual servers are migrated between the data centers in accordance with the migration plan.
