Container dynamic migration method and system based on minimum migration quantity

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,...

[0007] (2) Uncertainty of workload: In actual cloud computing services, at different times and different servers, there may be a large demand for a resource in a short period of time, that is, a container on a certain server CPU occupancy will suddenly increase

Although the Docker container has the advantages of convenient migration and dynamics, these characteristics will also bring some problems at the same time. Docker has a high degree of flexibility. It can package anything into a container and execute it in the server. The size of these containers may vary. There are thousands of differences, and the content will also be different. Some programs contained in containers may quickly generate a lot of random data, so the container size will vary greatly
