UPDATE MANAGEMENT SYSTEM AND UPDATE MANAGEMENT METHOD

摘要

In an update management system including a plurality of servers executing a communication service, a server not connected to a network in which a new version of an application is operated is generated in parallel with a server in which an old version of the application is operated, and old and new correspondence data between an old version server and a new version server is generated and used to execute switching from the old version server to the new version server in a flow on the network and to execute switching-back to the old version server by referring to the old and new correspondence data at the time of occurrence of fault in a new version.

主权项

1: An update management system, comprising:
a virtualization resource management node that manages each of virtualization resources including a physical server in which a virtual server executing a communication service is generated, and generates a new version virtual server based on an instruction to generate the new version virtual server; a service monitor that monitors the communication service executed by the virtual server; and a virtual communication function management node that instructs the virtualization resource management node to generate the new version virtual server, generates old and new correspondence data indicating correspondence between the new version virtual server and an old version virtual server, and notifies the service monitor that there is startup of the new version virtual server based on the old and new correspondence data, wherein the virtual communication function management node instructs the virtualization resource management node to perform network switching from the old version virtual server to the new version virtual server, and the virtualization resource management node executes network switching to the new version virtual server based on an instruction for the network switching.
