Research And Implementation Of Virtual Machine Cluster Management System In Cloud Environment

At present,cloud computing applications are everywhere,showing a trend of penetration from the Internet to traditional industries.With its large-scale physical facilities,cloud computing has powerful computing and storage capabilities,so that users do not have to be limited by geographical restrictions and terminal performance restrictions.They can use various network-connectable terminals to obtain cloud services at any location.Users only need to use the Resources without having to understand resource entities,thereby effectively simplifying the use of application services.Based on cloud computing technology,many enterprises and units have deployed their own cloud platforms to provide cloud services internally or externally.As the scale of virtual machine terminals connected to cloud platforms becomes larger,it is easy to manage the entire virtual machine terminal cluster from a single point A system bottleneck occurs and the reliability of the entire system is low.Therefore,it is necessary to design and implement a terminal management and control system that can operate terminal clusters in batches.It is necessary to avoid system bottlenecks and the system reliability to be strong.Aiming at the management and control of virtual machine terminal clusters,the thesis designs and implements a virtual machine terminal cluster management and control system.In order to avoid system bottlenecks in single-point management,a proxy terminal is used as an intermediate layer to assist the management terminal to control the entire terminal cluster;the Raft election algorithm is introduced and improved,so that the proxy terminal always performs as a better terminal,and avoids abnormal performance of the proxy terminal The performance of the entire system is reduced;breakpoint resume transmission technology is added during file transfer to avoid repeated file transfers and speed up file transfers.A performance display interface is added to the system to check the performance of the online terminal in real time,avoiding performing heavy tasks when the overall performance of the terminal is poor.The whole system is divided into five modules: terminal management,file transmission,command transmission,remote control and performance display.Each module is independent of each other,but coordinated with each other to complete the corresponding functions.It realizes the management and control of the virtual machineterminal cluster connected to the system,and performs batch file transfer,command transfer,remote desktop control and other operations.The system uses a proxy terminal as an intermediate layer,so that the management terminal indirectly manages and controls the work terminal,reduces the burden on the management terminal,and can play a good performance in the face of large-scale terminal clusters.Finally,a virtual machine cluster environment was set up to test all the functions covered by the system.The test results show that all functions have been implemented normally.This system can perform batch operations on terminal clusters,or directly operate target terminals through remote control.You can also view the performance of online terminals,which can effectively manage and control terminal clusters,improve work efficiency,and have higher use.value.
