Deployment with modern Java platforms/frameworks is simple. With Java EE you can create a runnable fat JAR just by running `mvn package` with WildFly Swarm. Spring Boot also has that capability and Payara Micro lets you deploy any existing WAR just by adding it as a command-line parameter.

Even a couple of years ago when this wasn't the case, it was still usually as simple as dropping your WAR in the autodeploy folder of your favourite app server (e.g. JBoss, WebLogic, GlassFish) - the main issue was that it was different for each app server even though it was (in theory) the same framework.

How do you deploy that to a server, let's say Digital Ocean? What kind of http server, proxies? Who/what starts and supervises the processes?

There are docker containers available for most of these. Spring Boot is made by Pivotal too, so has native CloudFoundry support if you want a PaaS. Docker is likely the most portable, but if you're happy writing an init.d start script or something you'd just need to call: java -jar /path/to/myapp.jar
