Example Embodiment

[0048] The following describes in further detail the container dynamic migration method based on the minimum migration amount of the present invention with reference to the accompanying drawings of the specification and specific embodiments.

[0049] The design scheme of the present invention emphasizes reducing unnecessary container migration during the migration process.

[0050] figure 1 Shown is the dynamic migration model of containers. The dynamic migration of containers is roughly divided into two stages. One is the pre-deployment and the selection of containers to be migrated. The other is the specific migration process, which involves network migration, storage migration and State (memory, CPU, I / O) migration. Among them, the monitoring module controls the entire migration process. It determines who is responsible for the initialization of the migration, the start of the migration, and the target location of the migration. The container migration decision module is respon...

Abstract

The invention discloses a container dynamic migration method and system based on a minimum migration quantity and designs a dynamic container migration model. The invention aims to provide a containerdynamic migration optimization method based on the minimum migration quantity. According to the method, by fitting increase speeds of containers in a source server, the containers for dynamic migration are selected according to the principle of selecting the containers with high migration increase speeds and high occupation rates. In this way, the migration quantity is reduced under the conditionof guaranteeing cluster load balance, and therefore the utilization rate of resources is increased.

Description

technical field [0001] Aiming at the problem of unbalanced cluster load on a container-based distributed cloud computing platform, the present invention designs a container dynamic migration method based on the minimum migration amount, and designs a dynamic container migration model. The invention belongs to the field of load balancing of containerized cloud computing platforms. Background technique [0002] With the continuous development of cloud computing big data platforms, containerized cloud computing platforms are gradually becoming a major trend and have been continuously developed. The traditional method of cloud computing virtualization is to virtualize a physical machine into multiple logical computers, and each logical computer can run a different operating system. However, in the traditional way, the cost of operation and maintenance and management is high, and the configuration is messy. In addition, the virtual machine cluster will connect multiple systems,...
