the update process on several frontend servers can be split into 2 modes: you can have an "incremental" update, in which the newer version of the application doesn't break the old one, and the "breaking" update, in which the newer version of the application breaks the old one.
in the first case, you can log into each one of the servers and update the app. in the second case, you need to log into each server, put the application in "maintenance mode", update each server, and then revoke the "maintenance mode" on each. there are SEVERAL ways to do it, some more elegant and intricated, some more simple and maintainable. Start with basics: prepare a makefile or a procedure that updates a single node, then execute it in a "foreach server" loop. It can be bash, python, go, whatever you're more comfortable with. Draw the procedure on a sheet of paper first (yes, it gets the deal done to unravel the necessary steps beforehand) and then implement each piece. I use fabric to handle the automation part wherever I can. Bash makefiles or powershell scripts where I can't.
