A method in a network of interconnected computer systems includes generating a Quality of Service (QoS) requirements document between a client and a first server for execution of a service in the first server, initiating execution of the service in the first server in response to a client request, and migrating execution of the service from the first server to a service in a second server if the first server cannot guarantee requirements specified in the QoS requirements document.
