Java web server build, what to do with TomCat?

Question

Java

There is a spherical web server that can do different goodies at the request of the client. During the development of this server, everything works with the help of TomCat.
The question is, if I want to run this spherical server, so to speak, in a "live" environment, then ... how? What is needed? Where? and where to read, of course.
Upd. As a result, I would like to get the installation with one button \ command. + installation will be on Debian OC
I hope that I have more or less clearly outlined the essence of the issue.

Answer 1

Deploy Tomcat on your "live server" and deploy your application there.

Answer 2

deploy to tomcat - the last century)
screw spring boot and build a thick war-ku with "embedded" tomcat as an option
then the whole launch will be reduced to
./myapp.war
