| With the rapid development of computer technology,people are suffering all kinds of security problems while entering the information stage:important information is frequently stolen,network is invaded illegally or system crashed.How to monitor bad information on Internet is a long-term research and developed issue in the field of information security.As the development of network and the technology of computer, the traditional monitoring technologies'shortcoming is more obviously,and it is difficult to meet the people's need for information security.The cloud monitoring system based cloud security uses cloud to integrate resources and monitors node computers on Internet.This monitoring system has a tremendous superiority and broad development prospects.Therefore, studying the principle and the form of cloud computing and deeply analyzing on cloud platform is necessary,and then a more mature cloud monitoring system is built to open up the application of cloud security. The following several aspect work has been done:The definition,technology structure,service mode and configuration mode are given. It also talks about popular cloud platform currently, analyzing their own merit and shortcomings.Especially analyzing the Amazon cloud platform and its key techology in detail;a more mature cloud monitoring system is built,which is based on B/S structure.The system divides four parts in function view:data monitoring, threshold value setting,? parameter collecting and node controlling.Before realizing this system,architecture and monitoring flow are explained.Realization thought and part codes in above four parts are given.In the end, evaluating performance in the form of data;It looks to the future and developing trend of cloud computing and analyzes its current shortcomings. In a word,this is a good quest for the principle of cloud computing?and cloud security,and it provides basis to study principle and advanced application further. |
