Problems solved by technology

[0003] However, due to the migration of computing nodes one by one, the maintenance time is long; although method 2 performs batch maintenance after concurrent migration, the number of computing nodes to be migrated at one time is a fixed value manually set, which is not flexible enough and There is still room for further improvement in migration efficiency

Embodiment 1

[0104] Such as figure 1 As shown, the embodiment of the present invention provides a flow chart of a method for migrating computing nodes. The execution subject of the method is the management node in the computing cluster. The method includes the following steps:

[0105] Step 101, obtaining the current load ranking of each computing node in the computing cluster;

[0106] The computing cluster is used to manage multiple computing nodes, and the computing cluster consists of a management node and several computing nodes. Among them, the management node is used to manage the several computing nodes, and distribute the received task requests to relatively idle computing nodes according to a certain load balancing strategy. The task requests are sent by the management node to the computing nodes so that the computing nodes can process them This task request. A computing node may also be called a host, and in a cloud computing environment, a computing node allocates virtual com...

Embodiment 2

[0209] An embodiment of the present invention provides a device for migrating computing nodes, which can be a management node in a computing cluster, such as Figure 9 As shown, the apparatus includes: an obtaining module 901 , a first determining module 902 , a first simulated migration module 903 , a second determining module 904 , a third determining module 905 , and a concurrent migration module 906 .

[0210] Obtaining module 901, configured to obtain the current load ranking of each computing node in the computing cluster;

[0211] Wherein, the obtaining module 901 is specifically configured to: obtain the current load of each computing node in the computing cluster, sort according to the current load of each computing node, and obtain the current load ranking of each computing node.

[0212] The load of the computing node is the load of the virtual machine managed by the computing node. The load of each virtual machine managed by the computing node includes: the sum of...

Abstract

The invention discloses a method and an apparatus for migrating computing nodes, relates technical fields of communication networks, and can perform flexible concurrent migration to computing nodes according to the load conditions of the computing nodes in a cluster. The embodiments of the present invention, through obtaining the current load order of the computing nodes in the cluster, and determining the load in the load order is not zero and the computing node with the minimum load is the computing node the first analog migration to be performed currently; performing analog migration on the virtual machine managed by the computing node the first analog migration to be performed to the aimed computing node of the first analog migration, and determining the computing nodes has a smaller original load than the load of the computing node the first analog migration to be performed currently are the first batch of computing nodes to be concurrent migration, and then performing a first concurrent migration to the first batch of computing nodes to be concurrent migration. The scheme of the embodiment of the invention is suitable for computing node migration.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a method and device for migrating computing nodes. Background technique [0002] Cloud computing in the field of communication network technology is a computing model that provides dynamically scalable virtualized resources in the form of services through the Internet. When upgrading or repairing the cloud computing system, it is necessary to relocate the virtual machine in the empty computing node first, that is, migrate the virtual machine managed by the computing node to other computing nodes, and maintain the computing node when the load of the computing node is zero. Work such as upgrades or repairs. The maintenance of computing nodes can adopt the following two technical solutions: Option 1, in a computing cluster, remove the computing nodes in the computing cluster one by one, and then upgrade or repair each computing node one by one after relocation; Se...
