Dynamic generation and maintenance method of heterogeneous cloud host

Abstract

The invention relates to the technical field of network security, and especially relates to a dynamic generation and maintenance method of a heterogeneous cloud host. The method comprises the following steps: 1) a heterogeneous cloud host node whose isomerism is embodied by the diversified physical facilities, virtual machines and software; 2) a mirror image library management system comprising creating diversified virtual machines and software mirror images; 3) dynamic deployment of a heterogeneous virtual machines and software: when the virtual machine or the software is instantiated, generating virtual machines or software of different versions according to physical nodes and application attributes, and deploying the virtual machines or software on the physical nodes; 4) dynamic virtual machine migration mechanism: a development operation and maintenance unit performs security posture estimation on the current virtual machine and its operation environment, and performs initiative migration on the virtual machine according to a strategy; and 5) a dynamic virtual machine and software cleaning mechanism: cleaning the online virtual machines according to the security posture or periodically. By adoption of the method, the anti-attack ability of a cloud data center is improved, and higher security requirements of users and providers for cloud services and infrastructure are satisfied.

Description

technical field [0001] The invention relates to the technical field of cyberspace security, in particular to a method for dynamically generating and maintaining heterogeneous cloud hosts. Background technique [0002] Cloud computing is a supercomputing that integrates large-scale scalable computing, storage, data, applications and other distributed computing resources for collaborative work based on virtualization technology and provides infrastructure, platforms, software and other services with the network as the carrier. model. In the cloud computing model, users no longer need to purchase hardware and deploy software, but only need to pay the corresponding fees, and can easily obtain the required computing and storage resources through the network. According to the latest Forbes report, the global cloud computing market is expected to reach $390 billion by 2020. Among the Fortune Global 50 companies, 48 ​​companies are related to cloud computing. The new model of clo...
