Application cluster migrating method and migrating device based on service model

Abstract

The invention discloses an application cluster migrating method and migrating device based on a service model. According to the embodiment of the invention, the automated migration of all nodes and dependence of an application cluster are realized through the service model. Through analyzing a software mirror image on which each host machine depends, the host machine of a target data center is equipped with software mirror images on which the host machine depends in batch, the application cluster migrating speed is improved, and the downtime of cluster migration is reduced. The environmental parameter of a target application cluster is bound to a node configuration document template, the configuration file of the target cluster is generated, and thus the configuration file migrating efficiency of the application cluster is improved. The mirror image warehouse of the target data center is used as the mirror image agent of the target application cluster, a needed mirror image is obtained and cached from the mirror image warehouse of a source data center according to needs, and thus the mirror image installation of the application cluster is accelerated.

Description

technical field [0001] The invention relates to the field of cloud computing, in particular to a method and a migration device for application cluster migration based on a service model. Background technique [0002] A cloud application cluster refers to a group of servers that provide Internet or enterprise application services based on cloud computing resource pools. It usually includes multiple server container nodes, and each container node is composed of hardware resources and software stacks. Hardware resources include virtual computing, storage and network resources, usually provided by cloud resource pools in cloud data centers. The software stack of a container node consists of several layers of interdependent software, including operating system, platform software, and application software. According to whether the container node saves the runtime state, the container nodes of the application cluster can be divided into two types: one is the stateless container no...

AI Technical Summary

Problems solved by technology

[0005] 1. Redeploying application clusters: Redeploying application clusters involves cluster resource application, cluster software installation, cluster network configuration, migration of cluster data and configuration files, etc., many of which require manual intervention, which takes a long time and is error-prone;

[0006] 2. Migration of WAN virtual machines: With V2V migration, only the software and data of a single virtual machine can be automatically migrated, but the configuration files cannot be automatically migrated, and the network structure migration of the entire application cluster cannot be realized. Data center copy time is long

However, container technology only simplifies the software installation of a single container node, and does not solve the migration of container node configuration files and runtime data, nor does it solve the migration of the entire cluster topology and network configuration.
