Design And Implementation Of Chef-based Automatic Configuration System Of Cloud Environment

Along with the development of IT hardware and Cloud Computing technology,the technology of Virtual Cloud becomes increasingly matured.A variety of companies now embrace the Virtual Cloud technology in order to reduce costs comparing to maintaining the server.To sum up,the technology not only optimize the server resource but also rationalize the system architecture.However,the IT management team are face an exponentially increasing number of virtual servers to maintain even though the number of physical server is decreasing.Consequently,the frequent append and modification of server configuration raises the costs oppositely.Moreover,the IT management team are suffering from the low performance because of this trivial and repeating daily work.Therefore,it is essential for IT management team to release the human resource to significant tasks so as to improve the effectiveness and quality of their work.This thesis discusses the solution to the problems with IT management,for example,heavy quantity of work,too much manual and repeating work,failure of configuration validation,low accuracy,etc.This thesis primarily covers below tasks:(1)Design and implement a automatic configuration system of cloud as a substitution to the manual configuration and maintenance.(2)Create a new set of documentation templates for the automation system based on the company's IT management workflow and IT environment definition.(3)Create a new set of project templates for the automation system based on the company's IT management workflow and then generate the automatic configuration code from the automation system.(4)To further facilitate the daily IT management work,design a set of GUI to fulfil the common tasks,for example,configuration version control,code execution,etc.,from the user-friendly UI interface.The automatic configuration system of cloud has been put into practice and achieved the expectation.This system,which innovatively introduces the concept to generate the configuration code automatically,not only solves the problem of low productivity and accuracy due to the repeating daily work,but also copes with the high fault rate while manually automating the configuration code thereby fundamentally improves the generation of configuration code.
