Mirror image storage and distribution system for virtual machines

Abstract

The invention provides a mirror image storage and distribution system for virtual machines. The mirror image storage and distribution system comprises cluster management servers, local object storage servers, DHT-MAP mapping servers and QEMU block drivers, wherein the local object storage servers, the DHT-MAP mapping servers and the QEMU block drivers run on test computers of a distributed cloud computing platform. By the adoption of the mirror image storage and distribution system, batch and fast deployment of distributed cross-region virtual machines can be achieved, and the defects that the period is long, dynamic extension can not be achieved and usability is low when a traditional system and method are used for deploying the virtual machines can be overcome.

Description

technical field [0001] The invention relates to a system in the technical field of cloud computing, in particular to a system for storing and distributing virtual machine images. Background technique [0002] The rapid development of cloud computing, the continuous expansion of the scale of cloud infrastructure, and the increasingly diverse types of services carried by cloud platforms have put forward higher requirements for batch and rapid deployment of virtual machines in a distributed environment. On the one hand, a large number of enterprises continue to migrate traditional business to the cloud platform, and the expansion of existing infrastructure is affected by various factors such as energy consumption costs, and private cloud deployment gradually presents geographically distributed characteristics; on the other hand, more and more More enterprises and users choose to place applications and data in public cloud and hybrid cloud, and cloud providers also vigorously pr...

AI Technical Summary

Problems solved by technology

Its disadvantage is that due to the lack of redundant storage for each template, when the same type of virtual machines are deployed in batches, frequent data transmission will greatly increase the load on the storage node, especially when transferring across geographical domains

[0007] Therefore, it is necessary to propose a virtual machine image storage distribution system and method in a distributed cloud computing environment to realize batch and rapid deployment of distributed cross-regional virtual machines, and to solve the problem of long deployment period of traditional systems and methods and the inability to dynamically deploy virtual machines. Insufficient expansion, low usability, etc.
