3. Technical selection

• Frontend: using Vue-Vben-Admin based on Vue，to code the page.
• Backend: using Gin to quickly build basic RESTful API. Ginis a web framework written in Go (Golang).
• Config: using cobra and viper to implement json config file。
• Virtualization: linux using libvirt-go to manage virtual machines , windows using hyper-v
