Cloud application processing method, cloud application deployment method, related apparatus and system

摘要

A cloud application processing method, a cloud application deployment method, a related apparatus, and a cloud service system are provided. A cloud service provider server may include: a determining unit, configured to determine that a working state of a first virtual machine satisfies a condition for adding a virtual machine; an emergency unit, configured to: determine, according to a determining result of the determining unit, and an emergency policy corresponding to a first application running on the first virtual machine, a second application that has an emergency relationship with the first application, and instruct a second virtual machine on which the second application is hosted to run the first application deployed on the second virtual machine; a creation unit, configured to: create a third virtual machine according to the determining result of the determining unit, and deploy and start the first application on the third virtual machine; and a stop unit, configured to: after the first application is started on the third virtual machine, instruct the second virtual machine to stop running the first application. The solutions provided in embodiments of the present invention help improve a utilization rate of virtual machine resources.
