METHOD, SYSTEM AND DEVICE FOR ELASTIC SCALING OF VIRTUAL RESOURCES IN CLOUD COMPUTING ENVIRONMENT

摘要

Embodiments of this application relate to the field of cloud computing technologies, and in particular, to a method for a virtual resource in a cloud computing environment and a device, to simplify and rapidly implement elastic scale-up. When a cloud management device scales up a new execution device, before the execution device is successfully scaled up, that is, before a data routing table of each execution device is updated, the cloud management device sends an IP address of the new execution device to a load balancer, so that the new execution device can receive a service request allocated by the load balancer. When the execution device processes the service request, if a data module is required to process a process, the execution device still allocates the data module according to a previous data routing table. Therefore, elastic scale-up of the execution device is rapidly implemented, so that the execution device can rapidly process a service request from an external network.
