Method and device for adjusting virtual-machine resources

Abstract

In an example of the present disclosure, a method for adjusting virtual machine resources is provided. A VIP for a virtual service is distributed, and a scheduling policy and virtual machines (VM) for the VIP may be configured. The VIP and the VMs corresponding to the VIP are configured on an underlying physical device. When status information of the VIP is received, a new VM may be added into the VMs corresponding to the VIP in response to the determination that the VIP is overloaded based on the status information of the VIP. The scheduling policy of the VIP may be used to distribute bearer services to the VMs corresponding to the VIP.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a method and device for adjusting resources of a virtual machine. Background technique [0002] Currently, cloud computing is a hot topic, especially the virtualization technology of cloud computing, which is being widely used. In cloud computing, storage virtualization, server computing resource virtualization, and network virtualization are key features of cloud computing. In particular, server virtualization in cloud computing is popular because it is simple and quick to implement, and does not need to rely on overall network transformation and the construction of a large cloud computing platform. In traditional enterprise traditional data centers, the problem of low server utilization has always existed, and server virtualization can just solve this problem. Therefore, many traditional enterprise data centers, in the process of transforming to cloud co...

Problems solved by technology

In traditional enterprise traditional data centers, the problem of low server utilization has always existed, and server virtualization can just solve this problem. Therefore, many traditional enterprise data centers, in the process of transforming to cloud computing, based on server virtualization Modernization is the easiest and most effective measure to implement

[0004] In this process, the virtualization transformation of the server and the deployment and operation of the LB forwarding device are separated from each other. The server administrator and the network administrator are independent of each other. The business load operation and the management of the server virtual machine resources are disconnected from each other. After a failure or overload, the network administrator cannot perceive the state in time, nor can it adjust the server resources in advance to ensure the normal operation of the business; The resources of the virtual machine server are insufficient, and there is still no effective means to adjust the resource configuration. It can only be coordinated with the server administrator manually, and it takes a lot of time to restore the application.

[0005] Therefore, it is inefficient to manually handle this method according to the failure situation, and once a failure occurs, the business system will recover slowly
