The problem starts here: What is your tech stack for the app? The complexity will depend on that. I fiddle around with web development using Wt(https://webtoolkit.eu https://webtoolkit.eu) because I am comfortable with C++. For the deployment part of that project, it is just updating the Linux based OS on the hosting server with required libraries and setting up a reverse proxy. The rest just works. Here is the Wt reference guide: https://www.webtoolkit.eu/wt/doc/reference/html https://www.webtoolkit.eu/wt/doc/reference/html The only hard part is knowing C++ :) There is no complex script to run or gazillion amounts of not required "modules" to download etc. All the dependencies are already provided by the Linux distros.
