When I realize I have spent too much time coping wtih requests like drawing KM survival plot, or compare the relative expression of two genes or blah blah blah..., I think it's time to deploy some frequently used databases on the cloud. Since R Shiny is the most easy to use solution, I will try building a Shiny server on an Ali ECS.
Upon establishment of the server, I've encountered numerous errors. Fortunately, the server's log was recorded in /var/log/shiny-server/, so I can easily check them and patch up several dozens of dependencies and fix numerous server protocols. After ardous work, the Shiny server is finally up and running!
