A TECHNIQUE FOR OPERATING A SYSTEM CONTROLLER OF A VIRTUALIZED APPLICATION CLUSTER

摘要

A technique for operating a system controller of a virtualized application cluster is presented. The cluster comprises one or multiple virtual machines. In a method embodiment the system controller receives, from outside the cluster, control information defining a function associated with a virtual machine. It further receives, from the virtual machine, a request message including an identifier of the virtual machine. The method also comprises determining, based on the identifier included in the request message, the function associated with the virtual machine and booting information associated with the function. The booting information is then sent in a response message to the virtual machine.
